Control Expert Read_Var/Write_Var Parameters setting

[keithkcchan]

For the Read_Var or Write_Var Function Block, there is a GEST Array[0..3]  parameters to manage the data exchange where the GEST Array[2] (the #3 word of the array) is the timeout parameter with 100ms timebase. The default recommendation is 5 meaning 500ms for the timeout and retry I assume.

Does anyone notice what will be the behaviour of the operation if this parameter did not set and leave it zero. In case the the block does not successful execute, will the block restart itself or not?

Timeout determines the maximum waiting time for the response. The time base for this parameter is 100 ms (the value 0 corresponds to an infinite waiting value).

When the timeout elapses, the exchange is ended with an error report. Also, the system does not accept any responses after the end of the timeout.
