Of course you can use ES-ETH-PPI to simulate each PLC as a COM port on the PC in order to 

achieve the data communication and monitoring operation between PC and multiple PLC s 

 

3. The communication between the PC and multiple S7-200PLCs                                                                           

 

 

When multiple PLCs communicate with a PC via Ethernet, you need to set every ES-ETH-PPI 

connected with PLC as TCP Client, set the PC as the TCP Server, let every client ES-ETH-PPI 

takes initiative to connect the server PC. When VCOMM Virtual Serial Port Software work as TCP 

Server,it allows unlimited number of connected clients. 

 

Set the ES-ETH-PPI network parameters, the gateway of ES-ETH-PPI,PC and router must be 

same, the DNS server needn’t to be setted because you don’t use the dynamic domain name on 

the Internet. The picture below is a ES-ETH-PPI setted parameters, when there are multiple
