< 2025-12-02 >
- Increased the number of entries that can be registered in the Modbus RTU Master list.
< 2025-09-18 >
- Fixed a problem where a file saved with MP STUDIO V2.1.7 or earlier could not be read in the latest version when the communication setting mode was Modbus RTU or Cubloc Modbus RTU.
< 2025-09-08 >
< 2025-08-26 >
- Improved the noise rejection algorithm on the MPA-48A48R(T) and MPA-64A64R(T). (A software change following a hardware change in the output section.)
- MPA-48A48R(T) and MPA-64A64R(T) products made on or after 26 August 2025 cannot be used with MP STUDIO versions earlier than V2.4.8.
< 2025-07-17 >
- The MNET family was added, and the related MNET function blocks were added with it.
- MNET is a product family controlled over the Modbus RTU or LS Industrial Systems Cnet protocol without programming,
- and it can also be programmed. It is the existing MPA family with a DIP switch added for changing the baud rate and slave address.
< 2025-07-01 >
- Fixed a problem where the P52 output was weak on MPA products when a Y module was added.
< 2025-05-09 >
- Added support for using an encoder through the I2C communication port on the MPA family as well.
- It can be used as channel 2 in the ENCODER function block.
- A 4.7k pull-up is built in, so open-collector type encoders and similar devices can be connected.
- Note that this uses the I2C communication port, so I2C communication is unavailable while this function is in use.
- From V2.4.3 the MPS family can also use the encoder and high-speed counter functions through the I2C port.
- Fixed a problem where the used-memory information was recorded incorrectly when word memory was used as bits (D0.15).
< 2025-04-30 >
- Added support on the MPS-8A8R, MPS-16A8R and MPS-16A8R8T for connecting one encoder channel to the SDA and SCL pins of the I2C communication port.
- It can be used as channel 0 in the ENCODER function block.
- A 4.7k pull-up is built in, so open-collector type encoders and similar devices can be connected.
- Note that this uses the I2C communication port, so I2C communication is unavailable while this function is in use.
< 2025-04-29 >
- Added support on the MPS-8A4R(T)-S, MPS-8A8R(T)-S and MPS-16A16R for connecting one high-speed counter or encoder channel to the SDA and SCL pins of the I2C communication port.
- It can be used as channel 1 in the ENCODER function block or the HCNT (high-speed counter) function block.
- A 4.7k pull-up is built in, so open-collector type encoders and similar devices can be connected.
- Note that this uses the I2C communication port, so I2C communication is unavailable while this function is in use.
< 2025-04-23 >
- Added the SQRT (square root) function block.
- The SQRT function block must use the real-number memory area only. ( ex. SQRT IN: R0 , OUT: R1 )
< 2025-03-18 >
- The compile algorithm was changed.
< 2024-10-24 >

- Added a time-delay function to the Modbus RTU Master. (After a response is received from the slave device, the next data is sent once the delay in ms has elapsed.)
- Made it possible to open the website, the MP STUDIO user manual and the hardware manual as links from within MP STUDIO.
< 2024-07-15 >
- Increased the default IBUS Master timeout from 100 ms to 1000 ms.

< 2023-12-14 >
- Fixed a bug that occurred when the ENMOV function block was used as a double word.
< 2023-10-24 >
- Changed full screen so that it no longer covers the taskbar. (Following feedback from customers who found it inconvenient.)
- Changed wire-break detection for ADC2 on the MPA family: a break was previously judged at 0.5 mA or less, and is now judged at 1.8 mA or less.
< 2023-08-11 >
- Added the PT312 function block. PT312 reads the value of an NTC temperature sensor with a B value of 4537K.
( It can measure temperatures from 0 to 130 ℃. PT312 does not appear in the function block toolbox; you can create it by typing PT312 in the function block input box. )
- The NTEMP function block algorithm was revised.
- Added the AFILTER (analog filter) function block. The analog filter weights the input value to suppress abrupt
changes. Its parameters are IN: the analog input value, WEIGHT: the weighting ( 0.0 to 0.99 ), OUT: the filtered value.
The closer the weighting is to 0, the less filtering is applied and the faster the analog value changes.
The closer the weighting is to 1, the more filtering is applied and the slower the analog value changes.
- Changed pasting so that function blocks can no longer overlap.
- Fixed a problem on the MPA family where selecting F also selected K.

- Fixed a bug in the monitoring function over Ethernet.
< 2023-04-11 >
- Added one channel each of MODBUS RTU MASTER to every MPS and MPA product.
You can register and use the function under MP STUDIO -> Settings -> Modbus RTU Master.

< 2023-04-10 >
- Changed the maximum number of logic lines from 1,999 to 9,999.
< 2023-03-28 >
- Doubled the number of I/O points that FORCE I/O can control. (MPA-48A48R, MPA-64A64R)

- Removed the delay after the CLCD Location function block runs, from 20 ms -> 0 ms.
- Reduced the delay after the CCLS (CLCD Clear Display) function block runs, from 2,000 us -> 1255 us.
< 2023-03-08 >
- The memory size and addresses of Force I/O changed, so on products ordered before 27 March 2023 every output may initially turn On.
For that reason we recommend performing this version update with no load connected. Running Clear under MP STUDIO -> Run -> Force I/O and then applying Force cancels all forced I/O.
Alternatively, please run an EEPROM initialisation.
- The MPA-48A48R(T) and MPA-64A64R(T) devices were added. They are scheduled for release.

- Changed the PID_PWM function block so that the MV value becomes 0 when its execution condition turns OFF.
- Changed the Duty and Width of the PWM and DAC function blocks so that real-number memory can be used.
- Changed the Modbus RTU slave communication protocol so that real-number memory can be used. (It uses Modbus addresses in the 5000 range. R0: 5000, R1: 5001, R3: 5002.)
- With the Cubloc Modbus RTU and LS Industrial Systems Cnet protocols, double-word memory is used to handle real numbers. ( Use the MOV function block, for example MOV : 12.34 -> DD0 or MOV R0 -> DD0. )
- R memory can be used with the Cnet protocol. ( Use R0, R1 and so on. )
- Changed the firmware download so that the program download also runs automatically afterwards.

< 2021-11-17 >
- The IBUS communication port protocol service starts.
IBUS is a protocol developed by us at ILOGICS and is used for communication between our own products.
Several SLAVE products can be connected to a MASTER product. (It can be used on only one of the communication ports.)
Please refer to the examples in the MP STUDIO/Example/3. IBUS/ folder.
<MASTER>
On the MASTER product, set the communication port that the SLAVE products connect to into IBUS mode in the port settings, and
you can use the digital input port #P(slave ID).(0~31) on NO contacts and so on for the SLAVE product. Ex) #P1.0
You can use the digital output port #P(slave ID).(32~63) on coil contacts and so on for the SLAVE product. Ex)P1.32
You can read the D0~D19 memory of the SLAVE product using ##X(slave ID).(0~19). Ex)##X2.0 (this reads the analog inputs)
You can send values to D20~D31 on the SLAVE product using ##Y(Slave ID).(0~11). Ex)##Y3.0 (this commands the analog outputs)
<SLAVE>
On the SLAVE product, set the port that connects to the MASTER product into IBS mode in the communication port settings and download.
To send the analog inputs of the SLAVE product to the MASTER, use the ADC function block to store them in D0~D19.
On the MASTER you can then read and use the ADC values with ##X(slave ID).(0~19).
To use the analog outputs of the SLAVE product, enter a value into ##Y(slave ID).(0~11) on the MASTER; this changes
D20~D31 on the SLAVE, and you then use those values with the DAC function block.
- The RF family products MRF-8A8R (Master / Slave), MRF-16A Master and MRF-16R Slave were added.
- Because of an internal structural change to the MPA family, customers who purchased MPA products on or after 1 September 2021 must use version 1.7.7 or later.
- Added the FDPWM function block. It outputs pulses at a specified frequency and duty.

- Increased the encoder inputs on the MPA family from 1 channel to 2 channels.
(Previously: P0:A , P1:B) -> (Now: channel 0 P0:A P2:B, channel 1 P1:A P3:B)
- Improved the product so that programs can be downloaded over all channels: serial communication 1 (RS-232), serial communication 2 (RS-485) and serial communication 3 (UART).
(This is possible only on products purchased on or after 5 July 2021, and the "Download Mode" checkbox must be ticked for that channel in the communication port settings; it is ticked when the product ships.)
(For details please refer to the MP STUDIO user manual.)
- Added a checkbox for setting download mode on serial communication channel 1. (Modbus or CNET communication and program download mode can be used at the same time.)
- When the download port is set to "ETHERNET", you can connect with the "Connect" shortcut icon to the right of the monitoring shortcut icon at the top of MP STUDIO, and then download and monitor
- Changed so that a DDNS name can be entered as the ETHERNET download IP.
- Added the high-speed counter function on the P0 and P1 input ports of MPA products.
(P0: high-speed counter channel 0, P1: high-speed counter channel 1, Max 7 kHz)
- Added the encoder input function on the P0 and P1 input ports of MPA products.
(P0: A, P1: B)
[ MP STUDIO V1.6.3 ]

- Added the MIN function block : D0 D100 5 -> stores the smallest of D0, D1, D2, D3 and D4 in D100
- Added the SUM function block : D0 D100 3 -> adds D0, D1 and D2 together and stores the result in D100
- Added the AVE function block : D0 D100 3 -> adds D0, D1 and D2, divides by 3 and stores the average in D100
- Added the MUX function block : D0 D100 3 -> stores the value of D3, the third memory location from D0, in D100

- Added the CTUD (counter up/down) function block
- Added the INC_I function block
- Added the DEC_I function block
- The FORCE I/O function was added.
Selecting Force I/O from the menu lets you force digital inputs ON/OFF without an actual input signal, so that the program behaves as if they were ON/OFF, and
lets you force digital outputs ON/OFF regardless of the program. (Note that this cannot be used on the MPS-8A4R-R2 and MPS-16A8R-R2.)
- The EEPROM initialisation function was added.
Selecting EEPROM initialisation from the menu lets you reset all data stored in the EEPROM to 0. Initialisation takes about 30
seconds, and MP STUDIO freezes during initialisation to prevent malfunction.

- Fixed a bug where symbol comments were not saved.
- The MPS-8A8R I/O numbers were changed.
- Some bugs were fixed.
- The transmit/receive buffer sizes of serial communication channels 1, 2 and 3 can now be changed under Settings -> Data memory.
When communicating with a touch display or similar device, increase the buffer size if many packets are transmitted or received at once.
- Added the ADC2 function block (ADC2 is the command for accepting a 1~5 V or 4~20 mA input)
- The MPS-16A8R8T digital input/output port names were changed.
( Ticking the "Use previous IO version" checkbox under Settings -> Data memory lets you keep the previous digital input/output port names )
- Added MPS and MPA category selection to the device selection window
- Added the MPA-32A16R(T) and MPA-32A32R(T) to the device selection window
- Added a receive timeout on communication channel 2 (RS485)
(The buffer is cleared if no further data arrives within 7 ms of receiving data)
- Added exception handling for errors during symbol configuration
- Added the FINI, FDATA and FINT function blocks for controlling an FND 7-segment display.
- They can be used on the MPS-8A4R, MPS-16A8R, MPS-8A8R and MPS-16A8R8T.
- On the MPS-8A8R and MPS-16A8R8T, using the FND function requires the protection resistor to be removed, so please be sure to
tell us that you will use an FND when you order.
- The shortcut icons were redesigned.
- Supports the CNET (LINK) protocol of LS Industrial Systems' Master-K and XBC.
MPS products can now be connected over communication to a wide range of HMIs.
- Added the ability to see and open recently opened program files from the Project menu tab.
- Symbols defined in the symbol table are now sorted automatically by memory type.
- Added links in the Help menu tab for opening the software and hardware manuals.
- The default data memory scheme was changed from the DW0 memory scheme to the D0 memory scheme.
Ticking the byte address scheme under Settings -> Data memory settings lets you keep using the previous DW0 memory
scheme as before.
- Added a Library function block for using the DS3231 RTC module.
- Added a Library function block for using a character LCD (PCF8574 module).
- For details please refer to the MP STUDIO manual and our blog.
- Changed program printing so that horizontal function blocks are printed.
- Changed so that no keyboard input is accepted in the function name of a horizontal function block.
- Fixed a bug in 1.4.0 where Ctrl+Enter did not work for creating a vertical function block.
[ MP STUDIO V1.4.0 ]
- The function block in the toolbox on the left was changed from the vertical function block shortcut to the horizontal function block shortcut.
The previous vertical function block is available with CTRL+ENTER.
- Removed "Undo, Redo, Copy, Delete, Paste" from the shortcut icons at the top.
They were removed because the bit contacts on the right are awkward to use at low resolutions, and because Undo, Redo and
similar commands use shortcut keys common to most software. They remain available as before
from the Edit menu at the top.
[ MP STUDIO V1.3E ]
Added bit commands to the toolbox on the left.
[ MP STUDIO V1.3D ]
- Fixed the error in version V1.3C of the MPS-16A8R(T)-R2
[ MP STUDIO V1.3C ]
- Fixed a problem where P10~P16 on the MPS-16A8R(T)-R2 were not recognised under the latest memory scheme.
[ MP STUDIO V1.3B ]
- Improved the error handling algorithm for Modbus RTU and Cubloc Modbus RTU.
[ MP STUDIO V1.3A ]
- The MPS-16A8R(T) device was added. (Product registration is currently pending.)
It is based on the MPS-16A8R(T)-R2 with bidirectional photocouplers on the digital inputs, allowing bidirectional input, and
adds 4 channels of analog input, 1 I2C channel, 1 RS485 channel and 1 UART channel.
- Fixed a bug with negative temperatures in NTEMP.
[ MP STUDIO V1.2 ]
- The horizontal function block feature was added.
[ MP STUDIO V1.2 ]
1. Horizontal function blocks were added, like those in LS Industrial Systems' Master-K (XGB).
The manual is still being updated; you can use them with the "[" key on the keyboard.
Ex) type [ and then ADD 1 2 D0 in the input box, and D0 becomes 3.
2. Auxiliary bit contacts for counters and timers were added.
When the up counter CTU uses C0 memory, the C0 auxiliary bit contact can be used
on an NO or NC contact.
For the On Delay Timer TON, when T0 memory is used, the T0 auxiliary bit contact can be used
on an NO or NC contact.
3. An up counter now keeps counting past its set value instead of stopping there.
4. When the MPS-8A4R(T)-R2 or MPS-16A8R(T)-R2 device was selected, the memory usage reverted to the previous scheme;
it now keeps the latest memory scheme. When a previously saved file is loaded, the previous memory scheme is used.
[ MP STUDIO V1.0A ]
1. The version numbering was changed to the V1.0 scheme.
2. The data memory address scheme was changed. (When a previously saved file is loaded, the previous memory scheme can be used. Alternatively, ticking the previous-memory-scheme tab in the data memory settings lets you use the previous scheme.)
3. Comparison contacts were added.
4. The Cubloc Modbus RTU communication protocol is supported.
5. Word and double-word user-defined memory were added.
6. Fixed a problem that caused errors during symbol configuration.
1. Fixed a case where opening certain saved files raised an error
2. The scheme for word values in the Modbus address map was changed.
3. Changed comments written as //comment so that the colour changes and they are shown on one line.
4. Changed the symbol table so that selecting several cells and pressing DEL clears all of the selected cells.
2019.06.13 Updata V0.0.6D
1. The design was changed.
2019.06.10 Updata V0.0.6C
1. Added the ability to use internal bits under a user-defined name with #MemoryName.
You can define a contact name such as #모터 on a coil contact and refer to #모터 on an N.O contact.
You can write anything after the "#" and use it as internal bit memory.
2. Changed so that a separate bit memory no longer has to be defined for rising/falling edge detection contacts.
:P: and :N: edge detection contacts previously required an internal bit memory such as M00 to be defined;
this is no longer necessary.
