Data Control Instructions

TPO

In this case, set the same value for the PID Control instruction’s output range and the TPO(685) instruc-

tion’s manipulated variable range. For example, when the PID Control instruction’s output range and the

TPO(685) instruction’s manipulated variable range are both set to 12 bits (0000 to 0FFF hex), the duty

ratio is calculated by dividing the manipulated variable from the PID Control instruction by 0FFF hex

and TPO(685) converts that duty ratio to a time-proportional output.

 External Wiring Example

Connect the Transistor Output Unit to a solid state relay (SSR) as shown in the following diagram.

Parameter Settings

Note When the output limit control function is enabled, set the lower and upper limits as follows:

0000 hex ≤ lower limit ≤ upper limit ≤ 2710 hex.

Execution

• The instruction is executed while the input condition is ON.

• When instruction execution starts, the output bit (R) is turned ON/OFF according to the duty ratio.
