5.2.1 Automatic communication function
(e) When the automatic communication parameters are set on GX Configurator-MB
When the automatic communication parameters are set on GX Configurator-MB,
the automatic communication function will be automatically started at the timing
shown in (5) (a) 1) of this section.
When the automatic communication function is active, and when the target slave
device is not in normal condition (disconnected, down, not ready for
communication, etc.), perform either of the following:
• After the target slave device is recovered, set automatic communication
parameters on the sequence program and start the automatic communication
function.
• Ignore the error (Exception message reception (error code: 7360
Response monitoring timer timeout error (error code: 7378
(a) Checking the automatic communication operation status
Use Automatic communication error status (X6/XE) to confirm the automatic
communication operation status.
(b) Confirming the error occurred
When an error occurs in the automatic communication, Automatic communication
error status (X7/XF) turns ON.
Also, any erroneous part of the parameters and error details can be identified by
the following:
1) Acquisition of the automatic communication parameter number for the error
Check the automatic communication operation status storage area (0C20
0C21 /0C22 to 0C23
H H
( Section 11.4.1 (5))
2) Error code check
In the automatic communication error code storage area (0C28
0C48 to 0C67
H
corresponding to the automatic communication parameter number identified in
the above 1).
( Section 11.4.1 (8), Section 11.4.3)
POINT
On the "Automatic communication status" screen of GX Configurator-MB, the
operation status and error code for each automatic communication parameter can
be confirmed.(
If the automatic communication function does not operate although no error has
occurred regarding (7), check the presence of the settings in the automatic
communication setting status storage area (address: 0CA8
0CAB ) in the buffer memory. (
