  1. Dear all, Original system: 1 SLC505 and 1 1747-SDN Aim: built up redundancy of whole system. This mean 2 set of PLC(SLC505, 1747-SDN, 1747-BSN) Question: Did the remote module(communicate through DeviceNet) can communicate to 2 1747-SDN at the same time??Is it possible to do so?? If yes, how can i modify the DeviceNet??

  2. About 1761-NET-ENI

    Thx for yr suggestion. I will use SLC505 in the future project. But due to budget, i can't use SLC505 instead of 1761-NET-ENI in this project, that's why i want to downgrade the 1761-NET-ENI. Did anyone know 1761-NET-ENI(Ser D , FRN 3.21) allow downgrade to FRN 2.50...?? Can i use FRN 2.50 on 1761-NET-ENI(Ser D)?? Thx alot.
  3. Background:SLC(Out-station) connect to 4 SCADA(Local SCADA(IFix) and 3 Master SCADA(Intouch)) through 1761-NET-ENI Problem: One Outstation, using 1761-NET-ENI(Ser B, FRN 2.50)...it can communication with 4 SCADA another 2 Outstations, Using 1761-NET-ENI(Ser D, FRN 3.21)..Got communication error. i can telnet to ENI(Ser D, FRN 3.21) to check the connection, i found that it only support 3 connection(but the AB website said it support 4 connection)..the local SCADA(Ifix) always can;t communicate with the SLC Can anyone give me suggestion?? I want to Down-Grade 1761-NET-ENI(SER D, FRN3.21) to FRN 2.50....is it ok??
