Use in the H system
S7 connections as H connections via ISO-on-TCP - adapting the monitoring time
When using the CP in the H system V4.5, you also have the option of creating fault-tolerant
S7 connections via ISO-on-TCP. When operating large numbers of connections via the CP,
it may be necessary to increase the monitoring time. Otherwise it is possible that some
connections cannot be established.
Depending on the firmware version of the CPU you are using, set the monitoring time with
the following method:
● H CPU with firmware as of V6.0
The setting is made in the properties parameters of the configured connection.
● H CPU with firmware < V6.0
The setting is made in the properties parameters of the CP.
