MNET Series is a family of communication slave products whose digital I/O, analog I/O, temperature sensor inputs, and high-speed pulse I/O can be controlled from a master device such as a PC, HMI, or PLC using Modbus or LS Industrial Systems Cnet.
The CPU module includes DIP switches for setting the baud rate and slave address.
Supports 1 RS-232 channel, 1 RS-485 channel, and 1 UART channel.
This product does not accept downloaded user programs. Select Modbus RTU Slave or LS Industrial Systems Cnet Slave when ordering.
8A, 16A, 32A, etc. is the number of digital inputs.R is the number of relay outputs.T is the number of transistor outputs.8A8R is a model with 8 digital inputs and 8 relay outputs.8A8T is a model with 8 digital inputs and 8 transistor outputs.| Model | Communication Protocol | Digital inputs | Relay outputs | Transistor outputs | RS-232 | RS-485 | UART |
|---|---|---|---|---|---|---|---|
| MNET-8A8R | Modbus RTU LS Industrial Systems Cnet | 8 | 8 | 0 | 1 | 1 | 1 |
| MNET-8A8T | Modbus RTU LS Industrial Systems Cnet | 8 | 0 | 8 | 1 | 1 | 1 |
| MNET-16A16R | Modbus RTU LS Industrial Systems Cnet | 16 | 16 | 0 | 1 | 1 | 1 |
| MNET-32A32R | Modbus RTU LS Industrial Systems Cnet | 32 | 32 | 0 | 1 | 1 | 1 |
Optional modules provide analog I/O, temperature sensor inputs, and high-speed pulse I/O.
Use the addresses for the communication protocol selected when ordering. The table shows each model's base digital input and output addresses.

| Relay outputs | 32–63 | P0032–P0063 |
The following optional modules can be added to the product configuration. The product is assembled and shipped in the selected configuration.
Users cannot add or remove I/O modules or optional modules.
| Code | Function | Points per module | Maximum configuration |
|---|---|---|---|
| X | Analog inputs | 4 points | Up to 5 units, 20 points |
| F | PT100Ω temperature sensor input | 4 points | Up to 5 units, 20 points |
| Y | Analog outputs | 3 points | Up to 4 units, 12 points |
| K | High-speed pulse outputs | 6 points | Up to 2 units, 12 points |
The combined total of analog inputs and PT100Ω temperature sensor inputs cannot exceed 20 points.
The combined total of analog outputs and high-speed pulse outputs cannot exceed 12 points.
Products with optional modules are custom-built, so exchanges or refunds may be difficult.
