Our PLC engineers know that many PLC timer and counter resources are fixed and scarce, and there is no way to expand, and small PLCs are especially stretched. Let's take the following brands of PLC as examples to illustrate:
Mitsubishi FX3U Series:
Panasonic FP-XH Series:
SIEMENS S7-200SMART SERIES:
INOVANCE H3U/S Series:
Introduce the completion timer and start the lecture directly.
1. Create a new DB block and create the following variables
2. Create a new FB program block and write it into the following program
Segment 1
Siemens
Huichuan
Segment 2
The reset timer is triggered immediately after each process value jump
Siemens
Huichuan
Segment 3
Siemens
By jointly calling the *process timer* variable to trigger the *variable, the timing time is assigned, and a timer can be used to complete a process.

Process output 1 is turned on 1S
Process output 2 is turned on 2S
Process output 3 is turned on for 3S
Process output 4 is turned on for 4S
Process output 5 is turned on for 5S
