chengyi23 Posted February 24, 2005 Report Posted February 24, 2005 Hi, everyone: 1. I want to connect to A1SHCPU via A1SJ71C24-R2 module using GPPW8. External wire has been finished: In PLC side I/F of GPPW, I choose C24 module. A1SJ71C24-R2 module does not appear in the pick list! why? 2. If I want to use dedicated protocol 1 to communicate with A1SHCPU, what settings I have to do? I hope someone can help me. thanks in advance. Quote
navillusi Posted February 24, 2005 Report Posted February 24, 2005 In selecting the type of C24 module, your only options are: AJ71C24 or AJ71UC24 as the others are for Q Select the AJ71C24, set the data rates etc to match how the card is configured and you will get on-line In answer to your second question, If I remember correctly, dedicated protocol 1 is used for plc to plc communtications, the dip/rotary swicthes on the card must be set according to the manual and be identical on each plc (except for stn no!)

chengyi23 Posted March 1, 2005 Author Report Posted March 1, 2005 navillusi, thank you very much for your reply. I follow the steps you offer, it can connect to A1SHCPU via A1SJ71C24-R2. But a wrong CPU name 'A3N' is got when I do 'Connection Test'. ( my PLC is A1SH ) Quote
