The 1747-ASB remote I/O adapter is a SLC 500 single slot, RIO communications link module. The module can be used as an adapter or slave, on the RIO link as well as the master of s remote expansion chassis. We are able to communicate through the 1747-ASB using a baud rate of 57.2k, 115.6k and 230.4k.
1747-ASB Troubleshooting
Check publication for error codes and explanations on the meaning of these codes.
Ensure dip switches are configured correctly, publication will also help with this process.
Check to see that the RIO cable is properly terminated on both ends.
Visually inspect RIO communications cable for damages if possible.
If using a scanner module be sure to double check configuration as well as G-Data used in programming
Visually check the module for damage such as burnt out components broken board as well as terminating pins that insert into the backplane.
Ensure the rack that the ASB module is being plugged into is in good working condition.
Parts being used for testing 1747-ASB:
1746-P2 x2
1746-A4
1746-A7
1747-SN
1747-L553
1746-OW8
1747-ASB Testing
We configure the ASB modules dip switch settings (check publication for assistance).
Slide the 1747-ASB module into the rack 1746-A4 rack in slot 1, along with the 1746-OW8 in slot 2.
Configure the scanner module to communicate at 57.6 kb, configure G-data to ¼ rack as well.
Download the program to the processor once configuration has been completed.
Once online the COMM light will illuminate green and the status screen will say run.
- Under the output file word 2 of the scanner module toggle bit 0 and output 0 will turn on the 1746-OW8 will turn on.
If the outputs turns on and the card tell us we are in run mode then the 1747-ASB module should be good, be sure to check publication for additional information.
The Allen-Bradley 1747-ASB is a SLC 500 I/O Adapter Module. This I/O Adapter Module has a Universal Remote I/O Adapter Communication Port and has a Communication Rate of 57.6, 115 or 230 kilobits/second.
