Set Up Error: This index number refers to a problem with the read or write setup
parameters [DDIA = B684, DDIB = B660]. These errors cause DDI
operation to halt.
10 = Scan time is at 0
Scan Time
(x100ms): This index number is used to specify the time period for the read and
write phases of the controller to PLC communications. Enter a
number from 1 to 255 (0.1 to 25.5 seconds). [DDIA = B685, DDIB =
B661]
Scan Overruns: This counter is incremented each time the read-write phases exceed
the specified scan time. If the counter is incrementing, the
communication transfer is not being completed in the allotted time.
The Scan Time should be increased. [DDIA = B686, DDIB = B662]
PLC Error: Exception Response Code sent from the PLC. [DDIA = B671, DDIB =
B647]
01 = Illegal function, not a valid function code.
02 = Illegal Data Address, not an allowable address.
03 = Illegal Data Value, the fetch quantity requested is not allowed.
Comm Error: This Error Code is used to report messages related to the
communication message. [DDIA = B672, DDIB = B648]
0 = no errors
251 = 53MC5000 hardware malfunction
252 = 53MC5000 hardware malfunction
253 = bad message, a bad message indicates that errors were
found in the predictable portion of the message
254 = bad checksum, the message frame is not properly formatted
255 = timeout error, no message came back from the PLC
Comm Error Count: This is a running total of the PLC Error Error that are not successful
