I have an SLC5/05 with a 1747-SDN card, I’m attempting to set up an IRC5 v5.07? controller as a slave to the PLC. I have modified the IP address of the controller as needed for my system, and created a DN\_Slave Unit in the IRC5, my system does not have the DN\_Internal\_Slave available, I assume due to version? In RSLinx, I can see an ABB DSQ652 IO card and my 1747-SDN card on the network, but I cannot see the IRC controller. RSLinx says nothing found at that node address.

My SDN card is set for a different node so there is no conflict there, and my baud rate is correct, checked and double checked.

From the EIO.cfg file, I have the bus and the DN\_Slave Unit setup as follows

EIO\_BUS:  
-Name “DeviceNet1” -BusType “DNET” -ConnectorLabel “First DeviceNet”  
-DN\_MasterAddress 21  
EIO\_UNIT:  
-Name “IRC5\_Slave” -UnitType “DN\_SLAVE” -Bus “DeviceNet1” -DN\_Address 21

Same address as required, bus is correctly referred.

My devicenet connection between the IRC5 to the DSQ is fine also. So something is wrong with the configuration of the slave in the IRC5 but I can’t find any documentation on what it might be. Do I need to create a Unit Type of DN\_internal\_slave? If so, what would be the settings for it?

My DN-SLAVE type is as follows (from the EIO.cfg file again)  
-Name “DN\_SLAVE” -BusType “DNET” -DN\_VendorId 8 -DN\_ProductCode 12  
-DN\_DeviceType 12 -DN\_ExplicitMsgEnabled -DN\_C1Interval 50  
-DN\_C1OutputSize 8 -DN\_C1InputSize 8

I also still need to configure the input and output size also, but didn’t think it should affect just seeing the unit in RSLinx, if anyone can help there it would be great. Do I do that in the EIO\_UNIT\_TYPE definition or the EIO\_UNIT definition?

Thanks for your help!
