    General Section Section G1 Communication Mode Introduction You can perform RS-232C/RS-485 communication between external devices by adding a communication board or unit to SPF. Up to five ports can be used (PORT 0 to 4). Port Nos. are defined according to the location of the SPF communication port. For details, refer to “G1-2 About communication port”.
  • Page 9 General Section (2) Loader communication This communication mode allows the connections shown below. 1) Connection to POD (MONITOUCH) No application program for communication is required. Connect to CPU loader port 2) Connection to PC loader Connect to CPU loader port PC loader USB connection Dedicated cable (NA0H-CUV)
  • Page 10 General Section * Notes on executing resource initialization of the CPU by the loader using Port 1 to Port 4 Be aware of the following notes when you use PORT 1 to 4 as Loader connection. If you execute resource initialization using PORT 1 to 4, set the parameter setting to “Loader” and download the project file to the PLC before resetting the PLC.
  • Page 11 General Section (3) CPU link communication (SPF mode) This communication mode enables data sharing between multiple CPUs (N-to-N communication). Data communication can be performed simply by setting the station No. and area in the parameter setting. Only RS-485 is supported. * CPU link communication specifications of SPF are different from those of SPB/SPE.
  • Page 12 General Section (4) Modbus RTU master communication SPF acts as a Modbus RTU master, and communicates with multiple slaves.

  • Page 20: H1-5 Communication Cable Wiring

    Hardware Section H1-5 Communication Cable Wiring H1-5-1 RS-485 cable wiring RS-485 provides connection for multiple stations. Its wiring distance must conform to the restriction specified in the EIA standard. For hardware wiring, observe the principle that connection distance should be as short as possible and the station should be far away from high noise sources.
  • Page 21 Hardware Section <Cable> Use the shielded twisted pair cables for connection. The cable quality is an important factor for transmission signal. When the baud rate is high, low quality twisted pair cables (e.g. PVC twisted pair cables) will cause extremely high signal attenuation and considerably shorten the transmission distance.
  • Page 22 Hardware Section <Topology> Topology is a graph structure of transmission connection. The topology of RS485 must be in a Bus structure. Connect all cables from the first station to the second station, from the second station to the third station, …… and then to the last station. Bus connection The shorter, The shorter,...
  • Page 23 Hardware Section <FG grounding> Though RS-485 network can be connected with two cables, the connection is easily affected by noise. To improve communication quality, the ground potential difference (common mode voltage) between two stations should not exceed the max. allowable common mode voltage of the RS-485 transmission IC.

  • Page 24: H1-5-2 Rs-232C Cable Wiring

    Hardware Section H1-5-2 RS-232C cable wiring RS-232C is used by 1 : 1 connection. The transmission distance is defined as maximum 15m at 19200bps by standard. Use cables sold for RS-232C. If used at a faster speed, the transmission distance must be shortened. For hardware wiring, observe the principle that connection distance should be as short as possible and the station should be far away from high noise sources to minimize the influence of noise.
