Precautions for Correct Use
Precautions for Correct Use
If Execute changes back to FALSE before Done changes to TRUE, Done stays TRUE for only
one task period. (Example 1)
If you want to see if Done is TRUE at any time, make sure to keep Execute TRUE until you con-
firm that Done is TRUE. If Execute is TRUE until Done changes to TRUE, Done stays TRUE until
Execute changes to FALSE. (Example 2)
This section describes the response codes stored in the output variable ErrorIDEx if an error occurs
during the execution of a CIP message communications instruction.
As response codes, general codes are stored in the ErrorIDEx output variable (DWORD data) after exe-
cution of a CIP communications instruction is completed. If an additional code is added, the additional
code is also stored.

01
Connection failure
A connection related to service failed along the connection
path.
02
Resource unavailable
Resources needed for the object to perform the requested
service were unavailable.
03
Invalid parameter value
See Status Code 20 hex.
04
Path segment error
The path segment identifier or the segment syntax was
not understood by the processing node. Path processing
stops when a path segment error occurs.
05
Path destination unknown
The path is referencing an object class, instance, or struc-
ture element that is not known or is not contained in the
processing node. Path processing stops when a Path Des-
tination Unknown Error occurs.
06
Partial transfer
Only part of the expected data was transferred.
07
Connection lost
The message connection was lost.
