Nom Module with M580 controller by Using control expert v15.3

[bhushanshiv]

We are facing the issue in NOM module while we are using 8 device.

For example: if our 3 device is power on and 5 device is power off than after the certain hours NOM module got hanged/ Not reading the data from salve device.

As it's need to be work on if all the devices is connected in one loop cable and some devices is power off then why communication is breaking.

Controller:-M580

NOM Module version: 1.6

Control expert V15.3

Pls guide for further action.

Issue will be in calling communication functions and defined timeouts in GEST table vs. timeout of serial line. If it's not done correctly then buffer of serial link could overflow.  Too many new communication function demands even older ones are waiting to timeout lead to buffer overflow. Buffer is same for both ports of BMXNOM0200 so problem of one will lead to error on both.
