There are restrictions on the maximum number of L & C type data that can be written. Refer to the PLC
Instruction Manual for details.
Words of L to Write: Beginning with the Starting memory address for the writes, this is
the number of Logical data words to be written to the PLC. Words of
data stored in the controller’s database as "L" type data is written to
the PLC as Logical data. If no Logical type data is to be written, this
value should be set to zero. [DDIA = B677, DDIB = B653]
Words of C to Write: Immediately following the Logical words of data is the number of
floating-point words of data to be written. Words of data and stored
in the controller’s database as "C" type data is written to the PLC as
Floating-point or integer data. If no floating point or integer data is
to be written, this value should be set to zero. [DDIA = B678, DDIB =
B654]
Write Command: This selection is used to tell the PLC the type of write to perform.
There are two supported options. [DDIA = B679, DDIB = B655]
0 = Protected Write
8 = Unprotected Write
PLC Error - Write: This Error Code is the reply status from the PLC that are not
associated with communications. Here the error code is reported as
a decimal number. The PLC manual may report these in
hexadecimal. [DDIA = B681, DDIB = B657]
255 = no reply
00 = successful - no error
Comm Error - Write: This Error Code is used to report a message related to the
communication message. [DDIA = B682, DDIB = B658]
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 -
Write: This is a running total of the non-zero PLC Error codes and non-
zero Communications Error codes. [DDIA = B683, DDIB = B659]
