How to input the timer command in Mitsubishi PLC programming software

If you want to enter a timer command, you should click the “-O-” button because the timer is handled as a coil.
Then enter data such as “t0 k100” format

In addition, the timers and counters of Mitsubishi plc are coil instructions instead of function instructions.

X0 is closed. The timer starts timing, and X0 is off. The timer is reset. X1 turns on the counter for a number of times, X1 turns the counter on again to count a number, and X2 closes the counter to reset.

Timer

T is the timer symbol, 0 is the number, K is the constant, it is decimal, that is, it is one second when it is set to K10.
The value oh D212 acts as the K value. Typically done when you want to allow a timer to be changed without accessing the program (from a numerical input on a HMI for example)

How to program MITSUBISHI PLC timer?

Timer: T0-T199 (200 points) is a 100 ms timer (set value: 0.1-3276.7 S); T200-T245 (46 points) is a 10 ms timer (set value: 0.01-327.67 S); T246-T149 (4 points) is a 1 mS cumulative timer (set value: 0.001-32.767 S, power loss retention, i.e. interruption); T250-T255 (6 points) is a 100 ms timer (set value: 0.01-327.67 S); Cumulative timer (set value: 0.1~3276.7 S, power loss maintenance, that is, interrupt action).

If T192-T199 and T246-T249 are used in subroutines or interrupt programs, the current value of the timer is modified when the END instruction is executed. When the current value of the timer is equal to the set value, its output contacts act when executing the timer coil instruction or the END instruction. If the timer is not used, the work of the timer may not be normal under special circumstances.

If a 1ms timer is used to interrupt programs and subroutines, its contacts act when executing the first coil instruction of the timer after its current value reaches a set value.

Use the T command format (Tn KX), is an example:

LD X0
OUT T0 K100

It means that when x0 is connected, time is 10 seconds and T0 is connected. Subsequent use of T0 to punish the required output points can achieve the purpose of controlling the time delay.

T is a timer symbol, 0 is a number, K is a constant, is decimal, that is, set to K10 is a second.

The manual says, using a special timer in T192 ~ subroutine and interrupt subroutine in T199, I now subroutine timer is not enough, can I use the general timer in the subroutine, in addition, for the 192~199 general and special Godson program timer in the end what is the difference?
Timer: T0~T199 (200 point) is the timer of 100ms (set value: 0.1~3276.7 S); T200~T245 (46 point) is the timer of 10ms (set value: 0.01~327.67 S); T246~T149 (4 points) is a 1mS cumulative timer (set value: 0.001~32.767 S, power loss retention, that is, interrupt action); 6 Cumulative timer (set value: 0.1~3276.7 S, power loss maintenance, that is, interrupt action).
If T192 to T199 and T246 to T249 are used in subroutines or interrupt programs, the current value of the timer is modified when END instructions are executed. When the current value of the timer is equal to the set value, its output contacts act when executing the timer coil instruction or the END instruction. If the timer is not used, the work of the timer may not be normal under special circumstances.
If the 1ms timer is used to interrupt the program and the subroutine, after its current value has reached the set value, its contacts act when the first coil instruction of the timer is executed.
