7-737.6.3 MonitoringWhen using a PC(PLC) link, the operation status of the links can be monitored using the following relays.Transmission assurance relaysFor PC(PLC) link 0: R9060 to R906F (correspond to unit no. 1 to 16)For PC(PLC) link 1: R9070 to R907F (correspond to unit no. 1 to 16) (For FPΣ 32k type only)If the transmission data from a different unit is being used with the various PLCs, check to make sure thetransmission assurance relay for the target unit is on before using the data.Operation mode relaysFor PC(PLC) link 0: R9070 to R907F (correspond to unit no. 1 to 16)For PC(PLC) link 1: R9080 to R908F (correspond to unit no. 1 to 16) (For FPΣ 32k type only)The operation modes (RUN/PROG.) can be checked for any given PLC.PC(PLC) link transmission error relay R9050This relay goes on if a problem is detected during transmission.Key Point: Monitoring the PC(PLC) link statusIn FPWIN GR, the PC(PLC) link status items, such as the transmission cycle time and the number oftimes that errors have occurred, can be monitored by selecting the PC(PLC) link switch on the FPWINGR Status Monitor screen.Note:Remote programming of the linked PLCs is not possible.
