1.Communication Timeout Register description
| PLC Address explain | |
| 40002 | 1-16 Road relay or code |
| 40003 | 1-16 Road relay and code |
| 40004 | 17-32 Road relay or code |
| 40005 | 17-32 Road relay and code |
If communication is interrupted for some reason, And the fault time is greater than the time set in the timeout register, Consider communication timeout (The fault indicator light on the module will be constantly on, Flashing only when communication is normal)
The output status of each channel after a communication timeout is determined by the following formula::
| Timeout output status Or code With code | ||
| Keep unchanged (default) | 0 | 1 |
| open | 0 | 0 |
| closed) | 1 | 1 |
example: To 16 Taking the relay module as an example
※When communication failure occurs, it exceeds 3 Request in seconds: 0~7 Road disconnection, 8~11 The road remains in its original state, 12~15 close. 1) Firstly, set the timeout period to 3 In seconds: Register 40008=30
Analysis: Register 40008 What are the units inside, What is the timeout period 0.1 Seconds
2) Reset the corresponding settings “Or code” And “With code” Register refers to:
40002H=0xF000 (1111 0000 0000 0000)
40003H=0xFF00 (1111 1111 0000 0000)
The result is: 0~7 Road disconnection, 8~11 The road remains in its original state, 12~15 close
3) Waiting for communication interruption 3 In seconds, You can see the effect immediately.
