Set UP:
This designates the data format transfer protocol. Clicking on the
"down arrow" reveals a list of 3 selections, these are [DDIA = B293,
DDIB = B459]:
8, 1, NO
8, 1, EVEN
8, 1, ODD
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.
0 = No error
2 = bad B value
4 = Initialization Routine running
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]
Comm Error - Read:
This Error Code is used to report message related to the
communication message. [DDIA = B682, DDIB = B658]
00 = Power-Up Clear Expected - Command Ignored
01 = Undefined Command - Illegal Command Character
02 = Checksum Error
03 = Input Buffer Overrun
04 = Non-Printable ASCII Character received
05 = Data Field Error
06 = Communications Link Watchdog Time-Out Error
07 = Specified Limits Invalid
240 - 247 = OPTO 22 Error Codes
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 cthecksum, the message frame is not properly
formatted
255 = timeout error, no message came back from the PLC
Comm Error Count -
Read:
This is a running total of the PLC Error that are not successful (PLC
Error other than 00). [DDIA = B683, DDIB = B659]
1st BAD Board Address: This value is the address of the first board returning a
communications error. Every time a board is accessed, it is checked
for communication errors. [DDIA = B687, DDIB = B663]
