For the DNSC port to be a master, the .CO file must use a MAC ID of 00. The Baud Rate must match what is set on the Slave devices. Then .SL file (Scan List) must contain an entry for each Slave device being controlled through the DNSC port. Each entry must be numbered, set to the correct MAC ID for the device, and include the vendor-provided information for Vendor ID, Product Type, Bytes Consumed (Robot outputs), Bytes Produces (Robot Inputs), etc.

Each slave device must have its MAC ID and Baud Rate set, usually this is done by DIP switches on the device. You will need to read the documentation for each device

Thanks a lot, this helped me so much. Today I tried this configuration, I was missing the MAC ID of 00 to identify the channel as a master.

Also the Poll numbers of each device was causing an error, but I read the documentation and now it is working fine.

Thanks again for the answer. Have a nice day.

Hi everyone.

I'm working with an old KR150L150 that uses KRC1. V4.1.4 SP02.

I'm having some issues making a connectio with a logix 5563 using a devicenet module. In the controller a LPDN card is being used, in channel 1 (x835) I have the plc. That works fine, I can send and receive signals between RSLogix and the robot.

The main issue comes when I try to connect three external devices. An SMC EX230-SDN1 and two interlinkBT with some sensors attached to them.

In a kuka-devicenet manual it says that a connection can be made using LPDN as master and slave, it can be achieved in two different ways. The firs one is using the same channel, and the second one suggests to use the first channel as a slave to the PLC and the second channel as a master to the external I/O devices.

Actually I'm trying the second solution. The files that are being used are: DNSC_1CO.INI, DNSC_1SL.INI, DNSC_2CO.INI, DNSC_2SL.INI and IOSYS.INI.

The files look like this.

IOSYS.INI

I hoe somebody can help me
