(1)Characteristics&TechnicalParameters

ES-ETH-PPI is the industrial product which use the Ethernet and Internet or 3G wirelss network to

achieve Siemens S7-200PLC networking communication. It integrates many complex network

protocols, support TCP Server,TCP Client,UDP Unicast,UDP Multicast etc many modes.It has

10M/100M adaptive Ethernet interface and 10-bit and 11-bit RS485 interface which meets

Siemens technical specifications.You only need to go on simple setting and then let the

S7-200PLC go on network communication.

The RJ45 port,RS485 interface and power supply port are all isolated in order to suit harsh

environment in the industrial situations. Especially the isolated power supply port and each signal

pin has anti-static protection and surge protection which can solve the communication port easily

damaged problem for Siemens S7-200PLC.

Notice: When ES-ETH-PPI is used to communicate between PC and S7-200 PLC,you need to set

the local connection as “Modem connection” in the STEP7 Micro/WIN software.When it’s used to

communicate between PLC and PLC,you only can use the free port RS485 communication

mode,can’t use Siemens PPI,multi-master PPI or advanced PPI protocol,also MPI and profibus

protocol.

Default Button: Restore the default setted parameters. Insert the penpoint into the hole to press the

button for about 1 second, the internal Flash memory parameters will restore to factory default

parameters: IP = 192.168.0.250, Username = admin, Password = admin. When you forget the IP

address,user name or password, you can restore to the factory default parameters,and then reset

the parameters.

RS485 Interface: RS485 interface is the DB9M-pin plug which meets the Siemens S7-200 Series

PLC PPI interface technical specifications, the signal array match S7-200 series PLC PPI

interface, and has a 0.5 meter cable, you just simply plug the DB9M directly into the S7-200PLC

PPI interface outlet.

RS485 communication mode selection switch: you need to set the local connection as “modem

connection” in the STEP7 Micro/WIN software when you use the ES-ETH-PPI . At this time, you

need to choose 11-bit or 10-bit data communication mode.

11-bit mode 8E1 communication mode with even parity, is usually used for

LAN(intranet)communication.

10-bit mode 8N1 communication mode without parity , is usually used for Internet

(Extranet) or 3G wireless network communication.

RS485 communication indicator: there are three LED indicators on the panel, and its working state

as the following table:

(4)ES-ETH-PPIparameterssetting

ES-ETH-PPI needs to be configured the parameters to work correctly, the configuration

parameters including the network parameters, communication protocols, connection, serial port

parameters; it can be very flexible to satisfy your application. Configuration parameters are

stored in the Flash memory, and they can be permanently stored without loss.

Use the standard RJ45 cable to connect the ES-ETH-PPI and router or switch, at the same time

make sure that the router or switch is connected to a computer in order to run the parameters

setting software .You also can use a standard RJ45 cable to directly connect ES-ETH-PPI and the

computer, no need crossover cable, this product has auto-polarity discrimination function for the

RJ45 cable.

Plug the RS485（DB9M）of ES-ETH-PPI into the S7-200PLC RS485 socket and power on the PLC.

The same local area network (router) can connect multiple ES-ETH-PPI, but the same IP address

is not allowed, there will be conflicts if the same IP , and it only shows one of IP and abnormality.

You can press the Default button on the ES-ETH-PPI any time that could make it restore to the

factory dafault.

IP=192.168.0.250，Username=admin，Password=admin

You need to check your computer's IP address and gateway address, and confirm your computer

is in the normal Internet access, in the next setting, you need to set the gateway of ES-ETH-PPI as

same as the gateway of computer and router, that is to say, the ES-ETH-PPI and computer are in

the same subnet, all equipments in this subnet and routers have the same gateway.

Right-click Network Neighborhood> View Network Connection> Properties, then pop up “Local

Area Connection Properties” window:

Select the General page; click the Properties then pop-up the following window, record the IP

address and the gateway of the computer for later use:
