Hi I found this forurm and since AB tech support isn't really any help I figured I would try here.
I have a SLC5/05 processor in a 7 slot rack. Slot 1 has a 1746-IO12DC Combination module. Slot 2 has a 1746-NIO4V. Slot 3 has a 1747-SN Scanner module. I have a remote rack set up as follows.. 1794-ASB with 1794-IB16, 1794-IB8, 1794-OW16, 1794-IE4XOE2.
I have it set up as Rack 1. The dip switches are set up as follows - S1, all on except #6 - S2, all on except #3 & #6.
I am able to get the discrete I/O on the remote rack without any trouble. The 1794-IB16 is at I:3/128 - 143. The 1794-IB8 is at I:3/160 - 167 and the 1794-OW16 is at O:3/160 - 175.
I am told I have to do BTW and BTR to obtain the analog and I am not familiar at all with this. I have tried to read manuals and do this on my own to no avail. I don't understand where I am to get the analog data from or how to write to the analog outputs.
Anyone got any ideas? Sorry for the lenght of the post just wanted to be thorough.
Thanks.
