Well it turns out that all of these problems were caused by bad media. You gota luv devicenet............

I have a 1747-SDN that is doing many different things that leads me to think it needs to be replaced. First the voltage is 33 VDC for supplying the flat media and I wounder if this is to high. Second I was installing a PE on the Flat media with the system down and when I got done and turned the system back on the problems started. I removed what I had done to see if had an effect on the system and it did not. Some background, about 7 months ago the system died and all I did to get going again was reset the card and it was off and running until now. I can not get into the the card and if I do it is a short period until I loose communications again. Each time I remove power and re aply it gives me something different that it did before. Some of the combination of the highlighted below will come up.

1747-SDN

Fat fingers on my part.

Any one know the pin out for the SLC500 RJ45 connection. I just need to know how this one end is wired so I can make a 2' cable to reach outside the cabnet. TIA

Thank you....

Hello all, I have red eyes from trying to find how to make this work. I want to pass a message from Node 1 on a Devicenet system to Node 2. This is just to start as I have 7 Nodes to pass information around to. For now I am trying to get the firs one passed. I just want to send a bit to let Node 2 to let it know that a downstream conveyor has stopped running and to shut down. Sounds simple but it has got me pulling out my hair. I have read information here as well as AB manuals and searched the internet and I am sure that I am missing something simple. Any Ideas?

Question: Should these just be true rungs to the MSG?

Thanks for the help Ken and Bob. I went with the PC Card 1784-PCD with the 1787-PCABL cable. All is working great and much faster than using pass through on the SLC503. I ran out of memory on an 8k SLC503 so the next project is to swap it out with a 16k SLC503 and then back to the messaging project.

What I have is a 1784 PCMK series B card for the lap top and I want to connect to the probe connection on the 1787-PLUG10R. What items do I need to make this happen?

Well it is the weekend so I must work on things such as motor installation and fixing guide rails and the like so I will start on the first part of next week and get back to you when I am done. Thanks for the information BobLfoot

Option 3 - A,B,C,D,E,F & G to A,B,C,D,E,F & G This would allow me to go from any one to any other one. The system I am working with was installed so communications could take place but no one has ever attempted to do so until now. I have just been working for this company for a few months and I an just now trying to piece together what was done and why.

net eni? I an not familiar with that one.

Thanks for the information Ken and rpraveenkum. What I want to do is DH485 useing program MSG instructions. I whish to talk from one CPU500 to another. There are 7 SLC 5/03 PLC's on the network at this time. I have been studying MSG instructions but fail to understand how to send a bit to tell one 503 that a conveyor on another 503 has stoped running and I want it to shut down the conveyors that it controls. Clear as Mud?

Did I say something wrong? I can reword the question if I need to, sometimes I do not state things just right.

OK Ken thanks for the help. Once again my overworked mind failed me.. I am trying to work with a DH485 system (see Atch). However the Master/Slave idea sure did get my mind running with some ideas. There is only one 1747-SDN on my network and it is on Node 1. Any way how about the DH485 route, any ideas anyone?

Sorry I am using SLC 503 on all nodes. A Bulletin 1747-SDN that is on Node 1. No on the 1799
