(4) Precautions for automatic communication parameter setting
(a) When turning ON the Automatic communication parameter setting request/
Automatic communication start request (Y4/YC)
Make sure both of the following input signal conditions are satisfied.
• Condition 1: Module READY (X0) is ON.
• Condition 2: Intelligent function module switch setting change status (X10) is
OFF.
(b) When automatic communication parameter setting completes with an error
The erroneous automatic communication parameter is stored in the Automatic
communication parameter setting result storage area of the buffer memory
(address: 0C17
H
/0C19
H
), and an error code is stored in the Automatic
communication parameter error code storage area (address: 0C16
H
/0C18
H
).
Identify the stored parameter, check the error code and take corrective actions.
Then make the parameter setting request again.( Section 11.4)
(c) Clearing the automatic communication function buffer
The Automatic communication function buffer input area (address: 1000
H
to
1FFF
H
/2000
H
to 2FFF
H
) and the Automatic communication function buffer output
area (address: 3000
H
to 3FFF
H
/4000
H
to 4FFF
H
) used for the buffer memory read/
write setting are not cleared when the automatic communication function is
started.
If necessary, clear these areas by a sequence program.
