9.3 Display of error states on the TAD control unit
9.4 Further error causes
Data interruption through VISIC100SF self-test
Self-tests are performed every four hours for RAM/Flash and CPU registers. Short
interruptions (between 8 μs and 140 ms) in communication to the Modbus-RTU/TAD
control unit interface are therefore possible and can lead to transfer errors/timeouts on the
Master.
