Hi everyone,
Brief overview of the issue:
I have a CompactLogix (pt No:1769-L36ERM) that is connected to a MicroLogix 1400 (Pt no: 1766-L32BXB) via Ethernet. Data needs to be passed to the MicroLogix from the CompactLogix to then be sent onwards via a RS232 connection. Due to company standards I'm required to put the messaging instructions in the MicroLogix, so the Micrologix will read the data from the CompactLogix. Unfortunately I have none of the kit with me for testing.
The issue is I'm unsure how to configure the message instruction in the Micrologix (RS500) to correctly read the data from the CompactLogix and I don't have any test kit available to play with to see it working.
Currently I've set up the following:
In the CompactLogix (RS Studio 5000):
All data is placed in an array (array tag is N10[0])
Map PLC/SLC Message - set to map file number 10 to Name N10
in the Micrologix:
Msg instruction created
Set up the Msg instruction as follows:
channel: 1 [integral]
Communication command: CIP generic
Data Table: N10:0
Size:12
Then what i'm less sure about is the target device data i need to input, The Service (Generic Get Attribute?), Class, Instance, Attribute. I can't find any examples of this online.
So if anyone has any good tutorials on how to do this that would be great or could run through it for me I'd be super grateful. Please let me know if you need any more information.
