TELLUS4/TELLUS3 (Ethernet settings)
Local Port Setting
This port number is used for communicating with V-Server or other stations that use SEND/EREAD/EWRITE/MES macro commands.
* This is not used for PLC communication.
- When own station information is registered in the Network Table in the screen program:
Check [Use Network Table] to set the table number.
*The IP address that is set in the Control Panel Setting on the PC is valid.
- When own station information is not registered in the Network Table in the screen program:
Specify inforamtion in this dialog.
PLC COM Port
This is for setting a port number to communicate with a PLC.
- [Specify Port No.] is checked:
Specify a port number set in the [Device Connection Setting] > [Communication Setting] in the screen program.
*When using an Ethernet unit and the port number is set by the Open setting on the PLC settings, this option must be ticked.
- [Specify Port No.] is not checked:
Unused port number is automatically assigned.
