Table 12: Extract from the preprogrammed tasks in the Modbus task list
The parameterized trigger event must take place for communication to start. For testing communication, the
parameter 8:D71 can be set with the brief designation "TestC" to 1 on the device under link 8. The link is then
started as a test. Otherwise there will be a wait until the parameterized trigger event takes place.
