Error messages
NOTICE
External errors (wiring or sensor errors) in safety I/O modules lead to the channel passivation ("0" values are delivered). As soon as an external error is fixed and this is recognized by internal safety I/O module tests, safety I/O module channels request an acknowledgment for their reintegration to the normal safety process control mode. The user can acknowledge such channels using dedicated channel bits(refer to Fig. 457).
Safety I/O module error messages are aggregated together with other module error messages in non-safety CPU.
