Hello all,
I have been attempting on and off for over a week to read the temperature out of a Watlow PM-6 to a Micrologix 1400 over ethernet. I will start by saying I am not well versed in ethernet CIP, however I can read an addressing chart and have made it work with AMCI and Emerson drives in the past. The Watlow is supportive of explicit communication (according to the manual).
Facts:
-PLC is at address 192.168.1.108
-Watlow #1 is at 192.168.1.121
-all subnet masks at 255.255.255.0
-I can successfully ping both from PC
-RSlinx recognizes Watlow on network
-connection light on Watlow flashes (no connection) but link light is lit solid
-There is 1 AMCI drive and a Maple PLC also on the Micro 1400 ethernet working fine.
I have tried in my MSG block "get member" 0x77,2,1 (class, instace attribute), "get attribute single" 0x68,1,1, and get assembly 0x77, all per the Watlow manual using the appropriate size of read bytes. I have also downloaded a program that does absolutely nothing other than try to get temperature and disconnected the HMI so only the Micro, Watlow and my PC are on the network, same error.
Mutihop in the Micro 1400 was set to 192.168.1.121 for all the above.
I have tried code that was sent to me for a SLC 5/05 with a MSG block that read the Watlow as a PLC-5, to no avail(the blocks are a little different RIX file vs. control block).
In every instance I have tried, my MSG block returns Error Code (hex): d6, Connection timed out by network. At this point I would be excited to get a different error code.
I have been through Google, manuals, another Watlow PM-6, and Watlow tech support to no avail (although they have seen it work).
Has anyone made this combo work? MSG block post? I am open to any ideas.
Thanks in advance.
