FUNCTIONS

4)
Even if no response is sent from the communication target slave, the
automatic communication function does not stop until Automatic
communication stop request (Y6) turns on.
5)
When the automatic communication function stops, the TCP
connections used by the automatic communication function are all
disconnected.
6)
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 (2) (a) of this section.
When the automatic communication function is active, and when the
target slave device is not in normal condition (for example, the target
slave device is disconnected, down, or not ready for communications),
or the QJ71MT91 is not ready for the communications, take either of
the following actions:
After the target slave device is recovered, set automatic
communication parameters on the sequence program and start the
automatic communication function.
(For the parameter settings performed by the sequence program,
refer to Section 9.2.3.)
Ignore the error (such as Exception message reception (error code:
7360
7378
(3) Automatic communication operation status
(a)
Confirming automatic communication operation status
Use Automatic communication operation status (X6) to confirm the
automatic communication operation status.
(b)
When an error occurs in the automatic communication, Automatic
communication error status (X7) turns ON.
Also, any erroneous part of the parameters and error details can be
identified by the following:
1) Acquisition of automatic communication parameter
number during error occurrence
Acquisition of the automatic communication parameter number for the
error Check the operation status storage area (0C20
buffer memory to identify the error. (Refer to Section 11.3.1)
2) Error code confirmation
In the automatic communication error code storage area (0C28
0C67
H
corresponding to the automatic communication parameter number
identified in the above 1). (Refer to Section 11.3.1 (7))
Refer to Section 11.3.3 for the error code.
POINT
(1) On the "Automatic communication status" screen of GX Configurator-MB, the
operation status and error code for each automatic communication parameter
can be confirmed. (Refer to Section 8.6.3)
(2) The QJ71MT91 guarantees the data between the programmable controller
devices and the network line in units of one word (16 bits).
