1. PrefaceThe network communication with its flexible connectivity and mobility caneasily penetrate the barrier of the information island. Though at earlydays, most of the network systems are deployed in commercialenvironment, but as the evolution of the manufacture technology, therequirement of CIM/CAM is prevailing. To reach this goal how to provide areliable and accessible medium is a key. Because the networkcommunication has the characteristics as demand, so can be foundnowadays in the industrial segment and used to bridge the communicationbetween the management level and field level. To meet this trend, FATEKprovides a series of Network interface modules, with which an economicand effective network solution for FATEK FBs-PLC can be obtained.Besides the network function, some of the modules also provide anadditional serial communication port for application.2.

3.

This port is a general purpose communication port4 Network indicators:LINK: Lit, when the Ethernet cable is properly working.RX: Lit, when detecting a signal activity of the Ethernet.TX: Lit, when the module is sending a message into the Ethernet.5 S e r i a l p o r t s ta t u s i n d i c a t o r s :RX: Lit, when detecting a signal activity of the serial port.TX: Lit, when the module is sending a message into the serial port.4
4. The Function of Serial Port ConnectorsPort3 Connector:The signal level of Port3 connector is of RS232(CM25E) orRS485(CM55E). This port can be treated as a general communication portof CPU module and used for peripheral applications.Port4 Connector:The signal level of Port4 connector is of RS485(CM55E). The mainfunction of this port is to couple the Ethernet signal to CPU module, thisport also can be treated as a general communication port of CPU moduleand used for peripheral applications. Whenever the FBs-CMX5E modulereceive a data packet from the Ethernet interface, the same data packetalso will appear at this port(Ethernet to serial port conversion). On thecontrary, if a data packet is received at this port and the destination isdue for network (by lookup mapping table), it will also appear at Ethernetnetwork. Because the multi-drop characteristic of RS485 interface, installone FBs-CMX5E can provide more than one PLC to hook on Ethernet.5. The Function of Ethernet Serial ConverterThe operation principle of Ethernet serial converter is to take this moduleas interface and receive all the messages from network that intend to thePLCs managed by this module then convert it to the serial signal that canbe accepted by PLC and transmit it thru port4. The operation iscompletely transparent, in other words, The CPU cannot distinguish themessage is from local or network, the reply message is the same withnormal RS232communication. When the FBs-CMX5E or FBs-CBEmodule(for clarity it will be referred as Ethernet module in followingcontext) receives the reply message of PLC will pack the message intonetwork data packet then send it to the network . It must emphasis herethat the network environment is complicated and not adequate for realtime d ata t r ansf er a nd ca n b e u s e m a in l y f o r m o n i t o r in g b ut n o t f o r c o n t r o l .The main reason to use the network for factory communication is for itsconnectivity. The application, which required to access one processor atsame time by multiple clients, previous was difficult to implement byRS232 and RS485 can now easily achieve by network solution .5
5.1Application ArchitectureBase on the different requirements of network application this moduleprovides two operating modes –Server Mode and Client Mode.When operates at server mode, the Ethernet module will wait for themessage coming from the network. After decode the received message itwill send the message thru serial port to the PLC main unit. The replymessage from the PLC will intercept by this module and packed into datapacket then transmit to the network hence complete a server modetransaction.When operates at client mode, the Ethernet module will wait for themessage coming from the serial port. If the received message is for thePLC located at the remote site connected by network, the Ethernetmodule will pack the message into data packet for network transmissionand send it to network. After send the message to network the Ethernetmodule will wait for the reply message coming from network, when itreceives the reply message it will direct the message to serial port forPLC hence complete a client mode transaction. The network connection ofEthernet module depicted in the figures at following chapter, for clarity,will only be drawn by a direct link. Actually the network interface of theEthernet module is 10BaseT, which should attach with Hub in order toconnect with network.5.1.1 Server ModeWhen operates at server mode, the direct connected single PLC orthe stations connected by RS485 are all work at slave mode, whichwill wait for command message passively and reply the command.Follows are example of server mode application6
The example illustrate on above is the simplest server modeapplication. Work station A and work station B are master that cansend the command message actively to FBs-PLC, Upon receiving thecommand message, Ethernet module will send the message thru theport4 to FBs-PLC. When there are more than one message intendedto send to FBs-PLC, the Ethernet module will save the additionalmessages into the message queue then send it to FBs-PLC in orders(Must wait for the reply message before send the next command)therefore there will no conflicts.When work at this mode, there is no need to write any program inPLC for operation.Multiple PLC connectionUnder this application architecture, The PLCs connect the Ethernetmodule with the RS485 interface of port4. The work station A and workstation B are master that can send the command message actively toFBs-PLC, Upon receiving the command message from the network,Ethe rne t mo dule wi ll re-se nd the mess a ge to FBs -PL C t hru port4 inte rface .When the message appears at RS485 line, each PLC will compare thetarget station embed in message against its own station ID. If the result istrue then it will reply according to the command message. The replymessage will intercept by the Ethernet module and re-pack then send tothe network. When there are more than one message intended to send toFBs-PLC, the Ethernet module will save the additional messages into themessage queue then send it to FBs-PLC in orders (Must wait for the replymessage before send the next command) therefore will not have conflicts .7
When work at this mode, there is no need to write any program in PLC foroperation.5.1.2 Client ModeWhile work at client mode, the Ethernet module will wait the commandmessage at port4. When it finds the message is for the PLC stationlocated at remote site(Please refer section 5.3.6 for setting) then it willpack the message according to the content of port mapping table andsend it to the network. After that, Ethernet module will keep an eye onnetwork for the reply message. Upon receiving the reply message, theEthernet module will decode the message then send back to PLC thruserial port hence complete a client mode transaction. When work at thismode, the direct connected single PLC or the master station of PLC LINKconnected by RS485 interface are all operated at master mode, whichmeans it use LINK instruction mode0 to send the command actively. Theclient mode also can be further divided into standard mode and virtualserver mode. Explanation as follows5 . 1 . 2 . 1 Sta n d a r d C l i e n t M o d eWhen work at this mode, the master PLC connected with Ethernet modulecan use L INK inst ru ction mo d e0 send t he co mma nd messa ge to othe r PL C.The target PLC that master PLC intend to command can be a local slavePLC connected by RS485 interface to master PLC or a PLC located atremote site with sever mode Ethernet connection. There is a “Station tonetwork address translation table” in the Ethernet module when work atclient mode. This table includes the information about the mapping oflocal station and remote station, the user should set this table accordingto the actual application deployment (Please refer section 5.3.6 for tablesetting). While operation, the Ethernet module will constantly inspect thereceived message, if the station number in the message can be found inthe translation table that means the message is going to route to network,the Ethernet module will first replace the station number in messageaccording to the translation table then re-calculate and update the checksum of translated message and encapsulate it in network data packet andfinally send it to the network. After received the reply message from8
network, the Ethernet module will perform the translation of message atthe reverse order. First it will replace station number in message to theoriginal station number and then re-calculate and update the check sumof message then send it to serial port. A standard client mode networkapplication is shown as follows.In the above figure, there are two groups of PLC. The PLCs in each groupare linked together by RS485 interface and then attach to an Ethernetmodule for network accessibility. The station number 1 of group 1 is amaster PLC, which not only can access the other PLCs of same group butalso can access the PLCs of group 2 with the help of two Ethernetmodules bridging. The Ethernet module attached to group 2 PLC isconfigured as server mode, which means all the PLCs covered by thismodule are work as slave PLC and wait for the command passively. Itmust emphasis that the PLCs under standard client mode Ethernet modulecan’t access by other master devices thru network communication. Therole of this kind of Ethernet module is very similar to Fire Wall. Only themessages from inside or the corresponding reply messages can beaccepted by Ethernet module, other messages will be blocked. Thesecurity of client mode operation is very high. Based on the reasondescribed above, the workstation A can only access the PLCs of group 2 .It’s noted that, from the view point of master PLC, the station number ofstation #2 of group 2 is not 2, otherwise it can’t distinguish it from thelocal station of #2. This can be overcame by the introduction oftranslation table.9
5 . 1 . 2 . 2 Vi r t u a l S e r ve r M o d eThough high security is the key feature of standard client mode, can’taccessed by other devices thru network is also a drawback. To take thebalance between the security and connectivity, the Ethernet moduleprovides a virtual server mode to meet the both end. While working at thismode, the Ethernet module emulates a PLC with station number of 255.There are only R0 R1999 can be accessed of this virtual PLC. When thecommand message is for station 255, the Ethernet module will interpretthe message and act upon that message; this is true for all the messageswhether it comes from serial port or from network. The Ethernet moduleact as a medium, the status of PLCs can store in it for outside worldaccess. The outside world can put the command status in it for PLCsaccess. The virtual server mode is an option for client working mode,which means while act as virtual server the master PLC still can accessthe slave PLCs that attached to network.5.2 Hardw are Installation5.2.1 DIP Sw itch Setting5.2.1.1 Termination resistor installation(FBs-CM25E/CM55E)In order to meet the termination requirement of RS485 network, allEthernet modules equip with a set of built-in termination resistor to easethe field installation. The termination function can be setup by the DIPswitch seen from the front cover as follow.TNWhen both switches are at T position, it means termination resistor is ineffective. When at N position means no termination resistor attached bythis module. When implementation, there are only two modules thatlocated at opposite far side need to terminated. Excessive termination willover load the whole network thus must be avoided.5.2.1.2 Password protection setupWhen the password has been entered (enabled), the user will berequested to enter a matched password each time when perform theconfiguration via configuration utility ‘ether cfg.exe’. In other words, incase the user forget the password then he/she no longer can modify themodule’s configuration. To prevent this situation from occuring, there also10
provides a jumper to disable the password protection temporary. Thisjumper can be accessed only when the module’s plastic cover is removed.The relative location of jumper is depicted at follow:JP1NO PASSWhen the jumper cap of JP1 is at upper position (linked by white line), thepassword protection is disabled. The jumper cap should put in the lowerposition when under normal operation.5.2.2 Cable WiringSerial port connectors:Please refer Appendix A, B for the Port3, Port4 signal description.Netw ork connector:The connector type of FBs-CM25E/55E is Euro 4pin plug connector whileFBs-CBE board is RJ-45.Please use the CAT5 UTP (un-shielded twisted pair) cable for networkconnection. The best recommendation is using the CAT5 STP(shieldedtwisted pair) cable 。The wiring of cable to network connector is listed as below.SignalTX TXRX RX-Wire ColorWhite-OrangeOrangeWhite-GreenGreenEuro -4 Pin341211RJ-451236DirectionOutput Output Input Input
5.3 Softw are Configuration5.3.1 Configuration Softw are and its FunctionT h e r e i s a a c c o m pa n y s o ft w a r e ”Ether cfg.exe” to aid the configuration ofEthernet module. This software is a windows-based software and has followingfunctions:Basic module Information setup- Includes IP (Network address),gateway, netmask, baud rate, operating mode, module name, moduledescription.Security setup- Setup authorized IP. With this function, only thecommand message issue by the host with authorized IP can be acceptedby Ethernet module. Hence can prevent the unintended access and keepthe system secure. There are 10 set of IP group can be set. Each groupcan contain one or more consecutive IPs.Local station to remote station mapping- The operating of FBs-PLCnetworking is purely transparent. When access the remote slave PLC byexecuting the LINK instruction of mode0 and with the help of Ethernetmodule, the master PLC does not know the remote PLC is connected bynetwork. In other words, the maximum number of slave station is still 254.When Ethernet module work at client mode, in order to translate the localstation into remote station, must first setup the translation ta
