(4) Precautions for automatic communication parameter setting

(a) Turn ON Automatic communication parameter setting request/automatic

communication start request (Y4) after Module READY (X0) and Basic

parameter setting existence (X3) have turned ON.

(b) When the automatic communication parameter setting is completed with an

error, the erroneous parameter is stored into the automatic communication

parameter setting result storage area (address: 0C12

H (3090)) of the buffer

memory, and an error code is stored into the automatic communication

parameter error code storage area (address: 0C11

H (3089)).

Identify the stored parameter, check its error code, take corrective action,

and make a parameter setting request again.

Refer to Section 11.3 for details of the error code.

input area (address: 1000

H to 1FFFH (4096 to 8191)) and automatic

communication function buffer output area (address: 3000H to 3FFFH (12288

to 16383)), which are used for write/read setting of the buffer memory, when

the automatic communication function is started in the status of Automatic

communication parameter setting, normally completed (X4).

Clear them as necessary using a sequence program.

(d) The automatic communication parameter setting is not allowed in the offline

mode (intelligent function module switch 1: 0001

H).

Set the automatic communication parameters in the online mode (intelligent

function module switch 1: 0000

H).
