Program Rung Descriptions
rung 1* Display rung. It allows the words which control the
module’s operating characteristics to be displayed or
changed using the data monitor mode of the industrial
terminal.

When switch 111/00 is closed, storage bit 050/04 is
energized for one scan. This bit subsequently is used in
rung 8 to initiate a load/enter sequence. The load/enter
sequence can be initiated manually at any time.
rung 6* Annunciator lamp 012/05 will be energized if any one
of the first five bits of the status monitor byte is energized,
signalling an alarm condition at the module. Bits 05, 06
and 07 are examined to prevent 012/05 from becoming
latched during block transfers.
