Relay Module Status
Each Auxiliary Relay module reports its status as part of the normal exchanges
with the main module. The bit assignments are as follows.
Table 248 - Relay Module Status

Bits 0...7 are common to all types of auxiliary module, bits 8...15 are specific to
type.
The auxiliary module controls Bits ...15; the main module sets bit 0.
If bit 0 is set, the remaining bits do not reflect the current auxiliary module
status.
If communication with an auxiliary module are lost, then the main module sets
a status bit to indicate an auxiliary bus fault. If communication are restored,
then normally the fault indication clears, noting however, if a configuration
activity has failed, then the fault indication remains set until a successful
reconfiguration is completed. Normally this reconfiguration is achieved by
downloading the configuration from the controller to the appropriate main
module
