* Most of the settings on the computer will be adjusted to match the settings on the unit.
*Here, we are using the local IP address (127.0.0.1) because we are connecting to Virtual-M3 on the same PC.
* The port number used to connect to Virtual-M3 is fixed. For details on the setting values, please refer to "PLC side settings" below.
PLC side settings
1.Check the connection method and port number of Virtual-M3
Open the system file (C:\ProgramData\yokogawa\VFAM3_Sys\setup.ini) in a text editor such as Notepad and check the settings.
In this example, the connection will be made via PortB (TCP/TP and binary, port number: 12291) with the default settings (PortA=1, PortB=2).
|
The connection method and port number for connecting to Virtual-M3 are as follows.
The port number cannot be changed.
If you want to change the communication settings, you will need to edit a system file.
System files C:\ProgramData\yokogawa\VFAM3_Sys\setup.ini
·setting Edit the PortA and PortB values of [PCLINK] according to your situation.
Note that setup.ini also contains configuration information other than the parent link. Do not change any setting information other than [PCLINK].
