MPINO STUDIO 2 Phase 4-1 · Timer Box Functions
These commands create a completion state from an input condition and elapsed time.
This ladder screen shows TON connected to a contact condition.
1. Common Rules
The TON family uses a 10 ms tick; the TAON family uses a 100 ms tick. A number is a tick count, and time literals such as 1h30m, 10s, and 500ms are accepted. Use T for a 16-bit timer and DT for a 32-bit timer. A bit contact for the timer address reads its done state. Initialize a retentive timer with a ladder RESET coil, not box-function RST.
① Entering 1m10s shows its conversion to 70 seconds and 7000 ticks above the input.
2. TON and TAON
TON
On Delay Timer
Accumulates time while the input is ON and turns the done state ON at the set value. When the input turns OFF, the current and done states reset to zero.
Syntax: TON T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition ON | T0=0 | TON T0 100 | 1 s later → T0=100, T0 done contact=ON |
TAON
On Delay Timer · 100ms
Provides the same on-delay behavior as TON with a 100 ms tick.
Syntax: TAON T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition ON | T0=0 | TAON T0 100 | 10 s later → T0=100, T0 done contact=ON |
3. TOFF and TAOFF
TOFF
Off Delay Timer
Turns the done state ON immediately with the input. After the input turns OFF, the done state turns OFF when the set time has elapsed.
Syntax: TOFF T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition ON → OFF | T0 done contact=ON | TOFF T0 100 | 1 s later → T0 done contact=OFF |
TAOFF
Off Delay Timer · 100ms
Provides the same off-delay behavior as TOFF with a 100 ms tick.
Syntax: TAOFF T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition ON → OFF | T0 done contact=ON | TAOFF T0 100 | 10 s later → T0 done contact=OFF |
4. TPL and TAPL
TPL
Pulse Timer
Turns the done state ON when the input changes to ON. It turns OFF when the input turns OFF or the set time expires, whichever happens first.
Syntax: TPL T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition turns ON once | T0=0 | TPL T0 100 | 0 s → T0 done contact=ON; 1 s later → OFF |
TAPL
Pulse Timer · 100ms
Provides the same input-held pulse behavior as TPL with a 100 ms tick.
Syntax: TAPL T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition turns ON once | T0=0 | TAPL T0 100 | 0 s → T0 done contact=ON; 10 s later → OFF |
5. TMON and TAMON
TMON
Monostable / One-shot Timer
Starts one pulse when the input turns ON and holds the done state ON for the set time. Input changes and retriggers are ignored during that pulse.
Syntax: TMON T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition turns ON once | T0=0 | TMON T0 100 | 0 s → T0 done contact=ON; 1 s later → OFF |
TAMON
Monostable Timer · 100ms
Provides the same one-shot pulse behavior as TMON with a 100 ms tick.
Syntax: TAMON T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition turns ON once | T0=0 | TAMON T0 100 | 0 s → T0 done contact=ON; 10 s later → OFF |
6. TMR and TAMR
TMR
Retentive Timer
Accumulates time while the input is ON. When it turns OFF, the current and done states are retained; counting resumes from that value on the next ON. Use a ladder RESET coil to initialize it.
Syntax: TMR T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition ON | T0=40 | TMR T0 100 | 0.6 seconds (60 ticks) → T0=100, T0 done contact=ON |
TAMR
Retentive Timer · 100ms
Provides the same retentive behavior as TMR with a 100 ms tick. Use a ladder RESET coil to initialize it.
Syntax: TAMR T0 100
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition ON | T0=40 | TAMR T0 100 | 6 seconds (60 ticks) → T0=100, T0 done contact=ON |
7. Troubleshooting
| Symptom | What to check |
|---|---|
| The delay is ten times longer than expected. | Check the 10 ms tick for the TON family and the 100 ms tick for the TAON family. |
| The done contact does not turn OFF. | For the TMR family, initialize the timer address with a RESET coil. |
