Sub-
The table below lists response codes returned after execution of the SEND(90)
and RECV(98) instructions, the probable cause of errors, and recommended
remedies.
The table below lists response codes (main and sub-codes) returned after
execution of the CV-mode commands, the probable cause of errors, and recom-
mended remedies. Upon receipt of some commands, the destination node will
issue a request to another node; the other node is referred to as the third node.
---
Service was interrupted.
---
Local node parameter is outside
of specified range.
Local node not part of Network.
Local node SYSMAC LINK Unit
was initialized during instruction
execution.
Destination node not part of Net-
work.
Destination node SYSMAC LINK
Unit was initialized during instruc-
tion execution.
Destination node is engaged in
receiving data.
Message packet was corrupted
by noise.
Response watchdog timer interval
too short.
DM Area overrun because of DM
Area size mismatch between
PCs.
An error has occurred in the local
node communications controller.
Check node number of local
node.
A CPU Unit error at the destina-
tion node has occurred.
Probable cause
Probable cause
---
Check the contents of the destination
transmission area of third node.
---
Set the parameter correctly.
Add to Network.
Execute the instruction again.
Add to Network.
Execute the instruction again.
Increase the number of transmit retry
attempts or re-evaluate the system so
that the destination node is not so busy
receiving data.
Increase the number of transmit retry
attempts. Perform an internode echo test
to check noise level.
Increase the value for the response
watchdog timer interval.
Check the first word of the data transfer
area at the destination node and reset if
necessary.
Take corrective action, referring to com-
munications controller errors and reme-
dies table at end of this section.
Set the node number correctly. Make
sure the node number is within specified
range and that there are no duplicate
node numbers.
Clear the error in the CPU Unit (refer to
the PC’s Operating Manual).
