5.2 Setting Using FXGP/WIN
This section explains the modem initialization setting and communication setting methods.
5.2.1 Setting communication by way of RS-232C port
It is not necessary to set the serial communication with a modem.
However, it is necessary to verify that another communication type is not used and whether the
communication setting is correct using the following procedure.
In FX PLCs, the communication setting can be executed using either of the following two methods:
1) Writing the value "0" to the data register D8120 using a sequence program
If another communication type is already set for another application, delete the sequence program which
writes a value to D8120.
2) Setting parameters using a sequence programming tool
By using the following procedure, verify that the communication setting is not provided.
1 Checking the serial setting (parameter)
Select [Option]-[Serial setting (parameter)] from the toolbar.
The following dialog box appears according to absence/presence of parameter setting.
1. When there is no parameter setting
The dialog box shown below appears to indicate that there is no communication setting.
Click the [No] button.
2. When there are already parameter settings
The dialog box shown below appears to indicate that the communication setting is being used.
Click the [Clear] button.
