Determination of the total response time
T
TOTAL
= T
IN
+ T
PLC
+ T
OUT
Example 1:
Input to extension module, activation of SLS and processing in PLC, output to basic module.
T
TOTAL
= T
IN_Erw
+ T
PLC
+ T
OUT_Base
= T
Cycle
+ 6 ms + T
Zyklus
+ 0 ms = 2 * T
Cycle
+ 6 ms;
Example 2:
Input to basic module, activation of SLS and processing in PLC, output to extension module.

OUT_Erw
= T
Cycle
+ T
Cycle
+ T
Cycle
+ 6 ms = 3* T
Cycle
+ 8 ms;
Example 3:
Input to extension module, activation of SLS and processing in PLC, output to extension
module.
