getTM5Delay

USINT

The variable can take the following values:

o0= OK

o[1..3]= 1 to 3 cycles without valid exchange

o-1= more than 3 cycles without valid exchange or invalid parameter

Example

The following example describes how to get the delay of the first TM5 Module:

VAR
   delay : DINT;
   //Slot ID is 1 for the first TM5 module
           slot_ID : USINT := 1;
END_VAR

delay = getTM5Delay(slot_ID);
