FS-CIF11: compatiable with CPM1-CIF11, CPM1-CIF12

The Instruction for Use of FS-CIF11

FS-CIF11 is the peripherals port and RS232 to RS422/485 interface module that is developped for Omron PLC . Its functions include more than Omron’s CPM1-CIF11 (peripheral mouth to RS422), CPM1-CIF12 (peripheral mouth to RS485), NT-AL001 (RS232 to RS422), 3G2A9-AL004-E (RS232 to RS422) module. It uses for CPM1A/2A, CQM1, C200H series PLC, and it can connect PLC peripherals mouth or RS232 communication mouth (automatic identification), the output is RS422 (4-wire full-duplex) or RS485 (second-line half-duplex). The product without an external power supply, communication distance can be up to two kilometers.
Below are the FS-CIF11 and Omron CPM1-CIF11 and NT-AL001 comparison:

FS-CIF11 and PLC or computer connections:
All the connections of FS-CIF11 and the PLC peripheral mouth, RS232 Serial and computer RS232 serial port use peripherial/RS232 socket (DB9M). The products internal circuit will automatically identify the peripherals and RS232 serial peripherals. With the use of peripheral connection cable which products equipped can connect the FS-CIF11 to Omron CPM1A/2A, CQM1, C200H, and other PLC peripherals directly. The connection cable of FS-CIF11 and PLC RS232 Serial or computer RS232 need users to make, referring to follow pictures. If use the shielded cable, please weld the shield layer on the cover of the two plugs.
The application of products:
The use of FS-CIF11 adapter can connect up to 32 Omron CPM1A/2A, CQM1, C200H and other PLC as RS485/422 top communications network, and connect PLC peripherals mouth, RS232 serial port or both mixed-use, the communication distance can be up to 2,000 meters. Connect shield with the FS-CIF11 "FG" on the terminal when use unshielded twisted pair.
1. second-line half-duplex RS485 communications network:
Turn the RS485 and RS422 selection switch K1 on the FS-CIF11 adapter to "485", and turn the terminal resistance setting switch K2 on the FS CIF11 of the networkstart and endto "R", and turn the terminal resistance setting switch K2 on other FS-CIF11 of the network to "OFF".

2. 4-wire full-duplex RS422 communications network
This way equals to Omron CPM1-CIF11 and NT-AL001.
Turn the selection switch K1 on the RS485 and RS422 of FS-CIF11 adapter to "422", turn the terminal resistance setting switch K2 on the FS-CIF11 of the networkstart and endto "R", turn the terminal resistance setting switch K2 on other FS-CIF11 of the network to "OFF".

1. the communication lines should choose the unshielded twisted pair which cross-sectional area should be more than 0.5 mm2 and 120-ohm impedance.
2. in order to prevent RS485/422 interface of the common mode voltage impact beyond the permitted range and even damage the reliability of communication interfaces, low resistance wires which cross-sectional area is 1 mm2 can be used to link up thesignal ground “SG” of all FS-CIF11 to eliminate the potential difference between all nodes on the network.
3. the cable length(extension)of all FS-CIF11 to the bus can’t be over 15 meters, otherwise they will have echoes, affecting the normal communications of the system. The best option is connecting FS-CIF11 with the RS485/422 bus directly.
4. about the settings of the terminal resistance, the function of the terminal resistance is to eliminate the waveform distortion caused by the signal reflection in the communication lines , turn the termination resistor setting switch K2 on the FS-CIF11 on the communication lines start and end to "R" (access terminals 120EU resistance), and turn the resistance setting switch K2 on other FS-CIF11 of the communication lines to "OFF" (not-to-end resistance).
5. when the communication procedures used at full-duplex mode, can only use four-full-duplex RS422 connection; when the communication procedures used half-duplex mode, they can use second-line four-or half-duplex RS485 full-duplex RS422 connection. Please refer to PLC use manuals, communication manuals and other related information about programming.
6. when connect the RS232 serial port, if your RS232 is no power serial port or the output current is small(as some PDA), you can add i5 V auxiliary power between 1pin and 5pin on the DB9 outlet of the FS-CIF11, 1pin to straight. 5pin to negative.
