The outputs of the ibaMS16xAO-10V and ibaMS16x20mA modules are protected against short circuit. Nevertheless a hardware error may occur, e. g. when the wiring is not correct.
When there is a hardware error, e. g. overtemperature, all channels of a signal root are set to safe state (0 V or 0 mA).
The error must be reset by ResetError_Ch[00..15] in ibaLogic, or „Reset channel error” in ibaPDA, see chapter Reset channel errors).
