Enter communication error detection interval [DCM (decimal), byte]
· If the JW-20CM does not receive data from a station within the specified time (initial value: 250
ms when fewer than 32 stations are connected, 450 ms when more than 33 stations are connected),
it turns OFF the communication monitor flag corresponding to this station. The specified time can
be changed by entering a different value at parameter address 007771
(8)
(communication error
detection time). Use the same value for all the stations.
Normally, this value does not need to be changed. Use the modules with the initial value (00
(H)
).
* Detection time precision:
–100 ms to +0 ms
Ex.: If the PC scan time is extremely long (exceeds the time specified above), the communication
monitor flag will turn OFF, even though there is no communication error. In this case, change
the value at parameter address 007771
(8)
to a larger number.
