Hi, My name is Dan, I'm new to the forums and I'm having a problem configuring a SLC-5 for a senior design project. I currently have no access to Rockwell's PLC tech support so any help would be greatly appreciated. I've included everything I can think of below, please let me know if there is more information you need.
Chassis 0 (13 Slot)
Slot 0 - 1747-L541
Slot 1 - 1747-SN
Slot 2 - 1746-IA16
Slot 3 - 1746-IA16
Slot 4 - 1746-IA16
Slot 5 - 1746-IA16
Slot 6 - 1746-IA16
Slot 7 - 1746-OW16
Slot 8 - 1746-OW16
Slot 9 -
Slot 10 -
Slot 11 -
Slot 12 -
Chassis 1 (10 Slot)
Slot 0 - 1746-ASB
Slot 1 - 1746-IA16
Slot 2 - 1746-IA16
Slot 3 - 1746-IA16
Slot 4 - 1746-IA16
Slot 5 - 1746-IA16
Slot 6 - 1746-OW16
Slot 7 - 1746-OW16
Slot 8 - 1746-OW16
Slot 9 -
Slot 10 -
I have the 87 Ohm terminating resistors on both side of the RIO connection.
The following are dip switch settings (which I believe are correct)
1746-SN
SW1
0 0
1746-ASB
SW1
0 0 1 0 0 0 1 1
SW2
0 1 0 1 0 0 0 0
SW3
0 1 1 1 1 0 1 1
The I/O configuration for the 1747-SN is as follows
Scanned Input Words- 32
Scanned Output Words - 32
ISR# - 0
M0 Length - 3300
M1 Length - 3300
G File Length - 5
I realize I have this set up so that my logical rack starts at Logical Rack 8 - Group 0 (which i have configured as a Full Rack in RSlogix 500)
I also realize that I have this set up as complimentary mode (we were having trouble getting anything to work in primary mode)
Right now we are getting a flashing red COMM light on the SN module and a noc message on the adapter. As far as I can tell this means I have something connected incorrectly or configured incorrectly.
If you guys could take a look at this and see if you notice anything glaring that would be greatly appreciated. Just a side note, I'm open to any suggestions and any assumptions that I have stated earlier I'm open to re-configuring.
Please help me get this working!
Thank you!
