  1. SLC multiple racks into 1756 (DH)RIO

    Thanks Bob Found a KB article (id/19047) which suggests setting virtual ASB in the IO tree, due to Logix500 only assigning 8 x 16 bit words per ASB So for 25 IB16 cards it looks like I will need 3 x virtual ASB setup with full rack, 8 words/cards and 1x ASB as 1/4 rack The physical ASB will retain its DIP switch settings as it is currently working, for first rack just need to swap out the 5/04 for ASB set for 24 IO cards ( mix of IB16, OB16 & NI4)  assign 3x virtual ASB, I'm sure its not going to be that simple but at least its progress
  2. SLC multiple racks into 1756 (DH)RIO

    There's only 1x 5/04 processor in this project, all other existing remote racks have ASB cards,  I had looked at the AENTR but £3k each x 5 for a couple of months use is way too much, I managed to pickup a 1747-ASB card on ebay for £100 and it will be useful in the testing phase and kept for further upgrade testing. Changing everything in 1 phase is not an option here, just too much to do in the time available, so we are left with a hybrid interim..... whatever that looks like AIB is little help, only showing AENTR, not ASB. Now beginning to realise why that is
  3. I am converting a multple rack SLC project to CLX and as a fist step I have to keep the SLC racks while converting to CLX processor. There is an existing CLX rack with 1756-DHRIO card talking to other SLC over DH+ and i thought it would be fairly simple to connect all the 8 SLC racks via the RIO channel. Except the first rack has 2 extensions with zero spare slots, where i was considering 3 x 1747-ASB, now can I use single ASB in slot 0 where SLC resided to connect to all 3? Same with another rack already on RIO, the first rack has ASB installed but the extension has no spare slots. The documentation I have suggests I can only address 8x 16 bit cards on each rack, or have i got that wrong, most of my cards are IB16 or OB16, just the very first rack has analogs. Is the 1756-RIO card any better at addressing 25x 16 way cards as 1 rack
