The Usage In The Lan; Step7 Micro/Win Software Setting - Siemens S7-200PLC User Manual

The application of ES-ETH-PPI is very flexible and diverse, not limited to examples described
below. You can use the ES-ETH-PPI to connect the S7-200PLC to the Ethernet in order to
achieve the data communication from PLC to PC,PLC to PLC, multiple PLCs to PC and among
multiple PLCs etc.It can also be achieved the worldwide data communication through the Internet,
or wireless data communication through wireless LAN, 3G network card, 3G router.

(5)The usage in the LAN

LAN communication generally refers to the same gateway, that is to say, the communication is
among multiple Ethernet devices which are connected to a same router.
The ES-ETH-PPI communication in the LAN needs to ensure that PC, ES-ETH-PPI and routers
have the same gateway, The gateway: 192.168.1.1, the computer IP address: 192.168.1.108,
ES-ETH-PPI IP address: 192.168.1.250 in the following examples.

1.STEP7 Micro/WIN software setting

Select RS485 communication mode switch on the ES-ETH-PPI to "11bit" , use the even parity
11 bit communication mode,then use the setting software to set ES-ETH-PPI serial port
parameters as 9600bps, 8E1(8 data bits, even parity, 1 stop bit).
When the VCOMM virtual serial port software running on the PC simulate ES-ETH-PPI as the
COM port on the PC, the next using is just like PC / PPI programming cable, but you should set the
local connection in the "set PG/PC interface" menu of STEP7 Micro / WIN software as "modem
