Trip on fault: Module 1,01,02 Block 1001 (FC 79) has S19 with value 100 (slave bad if defined I/O point bad)
This message means that the value of the indicated specification will cause the module to trip if the slave has a fault, or if there is bad quality on any of the inputs.
In this case, a CISI/O: Control Interface Slave [FC79] value 100 will cause a trip if any defined I/O point is bad. Value 101 is used to mark the slave as bad if any defined I/O point is bad, but will not trip.
The "trip" specification controls if the module / controller should fail over to the redundant processor if a hardware fault is found. If the trip spec is set to "trip on fault", the module will stop working. If it is set to "continue operation" on fault, the module will smoothly transfer control to the redundant module. This is the normal mode of operation.
This message is likely to show an error in the system configuration. It should be reviewed. The issue raised may be in unused logic or graphics, or have other realities that make it a non-issue.
