RFID SystemsIDENT I System P Network AdaptersIDENT I System PNetwork Adapters• DeviceNet coupler for up to 2 readheads all powered by the bus• 10/100 Mbit/s TCP/IP and Modbus/TCP Ethernet protocols• 4-, 8-, and 16-port Ethernet toserial adaptersThe IDENT I System P line supports TCP/IP, Modbus/TP,and DeviceNet using existing serial read heads. If the readhead size is not a concern, IDENT I System P may be theright solution. If a smaller read head is required, IDENTContol could be a possible option.EthernetThe Multiport DeviceServers are not specifically designedfor P+F serial devices, but they do have special firmware toenhance the performance and programming of any serialdevice, including IDENT I System P. The P+F protocolis completely integrated into the DeviceServer makingprogramming easy for the application developer.Ethernet protocols and featuresTCP/IPThe real advantage of these device servers is the one-toonerelationship between the read head and the Ethernetport. For example, read head 1 can be assigned Ethernetport 3001, and all other read head ports can also beassigned unique port numbers as well. No polling isrequired. When a tag comes into position, a command issent directly to the required read head. The user specifiesthe length and the string of data. The device serverautomatically calculates the and appendsthe terminating characters to the end of the string. Theresponse data length is known because of the specialcommands sent to the System P read head.ADMIN portADMIN port is another DeviceServer advantage. Thisunique feature is offered exclusively by Pepperl+Fuchs.A monitoring application opens this port, and informationabout the other open COM ports is sent at one-secondintervals. This information includes whether or not the portis open, and the number of bytes transmitted and received.The system sends an alert if the port closes for any reason.MIRROR portsMIRROR ports are another Pepperl+Fuchs exclusive. Theyenable up to three applications to receive data from thesame serial port. For example, serial port 1 has defaultsocket connections to 3001, 4001, and 5001. Only port3001 is set to send commands to the serial device. Noother applications can interfere with production-criticalhardware. Data returning from the serial port is sent to alldefault socket connections.EMAILAnother debug option is provided via email. There areover 10 different errors that can trigger an email, includingdevice power up. This error could occur after a brownout.Modbus/TCPModbus over Ethernet makes the connection to PCs,or PLCs seamless. The serial string terminations areautomatic and Modbus debugging ports are included. Thisallows easy setup and diagnostics at the customer site orat remote locations. The IVI option attaches a to the string, IRI attaches a to the string, andGEN will attach no termination and can be used for anyserial device regardless of the termination type.DeviceNetThe DeviceNet bus coupler can handle up to 2 read/writeheads. The same command can be sent to both headssimultaneously. The response data is sent back with thehead number to easily distinguish the information. Becausethe standard read/write heads are used over RS-485, thedistance between the head and the coupler can be up to1,200 m. Special shielded 5 m, 10 m, and 20 m cables areavailable. The produced and consumed sizes are set toa compact 9 bytes in/9 bytes out. This allows many RFIDsystems to be put on to one network without worryingabout running out of memory in the PLC.66Pepperl+Fuchs®Inc. • 1600 Enterprise Parkway • Twinsburg, Ohio 44087-2245 • www.am.pepperl-fuchs.comTelephone (330) 486-0001 • FAX (330) 405-4710 • E-Mail: sales@us.pepperl-fuchs.com
