Communication drop between NOC0301 and TSXETG100

[sinced]

Good day,

We have experienced a communication loss between M580 (via NOC0301.2) and ETG100.

In the PLC program, there is only one READ_VAR function and there is a dedicated section in the program to initialize all timeout to 2000.

When this occured, the timeout was showing 0.

What could be the cause of this ?

3 remarks:

1: Your READ_VAR function is using Read_GE1_1_Gest variable. You're setting the timeout in variable Read_GE2_1_Gest, so might be you did not set the timeout at all in (and keeps it as default 0).

2: Timeout of 0 is infinate, makes the READ_VAR wait forever.

3: Timeout value of 2000 corresponds to 2000*100mS = 200 seconds, which is quite long.

Sorry, I made a mistake while copying the section. The timeout is set to 2000 by this code.
