Description

SYS18

Status of Last Successful Decode

The module latches one of the bits in SYS17 and SYS18 (while unlatching all others) when it successfully decodes the
referenced command block and places the new data into operational memory. The module does not latch any bit asso-
ciated with an unrecognizable command block. Set no more than one bit at a time in SYS17 and SYS18.

This bit
latched ON:

Programming-error Alarms

The module latches bits when it attempts to decode a newly received copy of the subject command block and is forced
to discard the data due to the presence of a programming error in the newly received block. The module does not latch
any bit associated with an unrecognizable command block. The module unlatches each bit when it successfully de-
codes the referenced command block and places the new data into operational memory.

This bit
latched
ON:

when the module detected a programming error in:

B00

MCC The module ceases all action execution and sets its outputs to zero when forced to set this bit. The module

does not respond to any action execution commands as long as this bit remains SET.
