Description
The display for a multiplexer or a GP relay module. This
display indicates that the monitored module is in Slot 2 and
2
channels 10, 16, and 19 are closed.
The display for a matrix module. The top is the row
information, indicating that the relays on Row 3, Columns 1, 3,

The display for a digital I/O module. The first 2 digits on the left
("00" in this case) represents the "L" 8-bit port address. Adding
4
one to this value, the "H" 8-bit port address is obtained. Data
with a trailing decimal point indicates that the last operation on
that port was a WRITE, data without a trailing decimal point
indicates that the last operation on that port was a READ. This
display shows that the data last read from Port 401 is 255 and
the data last written to Port 400 is 254.
The top display is for the built-in digital I/O Port 090 (control
module) and the data from the last operation.
090
The lower display indicates that data last written to the bit
channel 091 is 0.
091
For a multifunction module, the first function on the module is
displayed, then the next. This display is an example of a
