CTI 2572 Installation and Operation Guide
100
HEX DEC DESCRIPTION SOLUTION
0292 658 MESSAGE ID MISMATCH
The response message contained an ID
field which did not match the ID field in the
command.
This error could be caused by a timeout value
which is too short followed by an attempt to
re-send. Therefore, by the time the response
to the first command arrives, you have already
sent a second command. You may correct
this condition by increasing the timeout value.
This may also be caused by an improperly
programmed server. If the server is a PLC
emulating a 2572 server, review the code and
correct as required.
029A 666 ERROR WRITING SERIAL PORT
The protocol manager encountered an error
while writing to a serial port.
Retry the command. If the error persists, this
condition may indicate a module hardware
problem. Contact CTI.
029D 669 CMD TIMEOUT ERROR
The time to process the requested
command exceeded the Command Timeout
value. Command processing has been
halted.
Note that the timeout value may have been
explicitly set in the Command Block or the
default may have been used (timeout = 0).
If you are using UDP, your first attempt to
send a message to a newly referenced node
may time out while the 2572 is performing
address resolution. Retry the command.
In some circumstances, you may occasionally
get a timeout error, especially with heavy
network traffic or remote modem data links. In
these circumstances, your logic should retry
the command.
This error may indicate a bad connection
(faulty cable, loose connector, etc.). Check all
cabling carefully.
If the error persists and you have explicitly set
the timeout value, it is possible that you have
set the timeout value too small. Try increasing
the value or using the default value.
029E 670 ALREADY BUSY ERROR
The protocol manager received a new
command prior to the completing the
previous command.
This error can also be produced by
simultaneously triggering two command slots
which reference the same command block.
If more than one command slot is used, make
sure that they reference different command
blocks and that the command blocks that they
reference have different connection numbers.
