Hi
I hope that someone can help me with some info on SLC500 remote I/O.
I have a project that requires the following I/O modules installed in a 13 slot remote chassis (1 slot addressing) connected to a 1747-SN RIO scanner in the local chassis. The CPU will be a 505
Slot 0 – 1747-ASB Remote I/O Adaptor
Slot 1 – 1746-IB16 Digital Input Module
Slot 2 – 1746-IB16 Digital Input Module
Slot 3 – 1746-IB16 Digital Input Module
Slot 4 – 1746-OB16 Digital Output Module
Slot 5 – 1746-NI8 Analogue Input Module
Slot 6 – 1746-NI8 Analogue Input Module
Slot 7 – 1746-NI8 Analogue Input Module
Slot 8 – 1746-NI8 Analogue Input Module
Slot 9 – 1746-N08I Analogue Output Module
Slot 10 – 1746-N08I Analogue Output Module
From reading the SN and ASB manuals it seems possible to do with block transfers, but I’m not entirely sure how to do it.
Correct me if I’m wrong, but I figure that logical rack 0 is a full rack (physical slots 1 to 8) and logical rack 1 is a quarter rack (physical slots 9 & 10).
Is it possible to configure the RIO this way? Can I get this much data over RIO?
Just to throw a spanner in the works, there will be another scanner in the local chassis connected to a similar RIO setup. Is this possible?
Some background: The client is driving the hardware selection … I wouldn’t have done it this way, but we have little choice. I would have gone for CLX and Profibus or DeviceNet/ControlNet.
