CIP messaging without PLC

Hi All,

I am trying to setup the parameters in some Baumer mag absolute encoders on Ethernet/IP. Their damn manual is still in draft form but I'm figuring it out slowly.

Is there a way to send CIP messages without a PLC on windows? The manual uses Wireshark to read/write data it looks like but I can't quite follow it.

The manual provides instance/attribute/etc for the variables I need to change.

Help?

I expect the Advanced HMI guy to show up soon his program might be able to help with this.

Just would like to use the get/set single attribute

When I use RSNetworx for DeviceNet, there's a "Class Instance Editor" that lets you send simple CIP messages directly from the software. I don't know if there's a similar function in RSNetworx for EtherNet/IP,

The best tool for testing EtherNet/IP products is EIPScan. Several vendors re-sell it, but I think it was developed by IXXAT:

I think that an explicit message client was built into FactoryTalk View's driver set (RSLinx Enterprise) in v7, so if you have FTView Studio or a PanelView Plus those might do the job.

Each of those are licensed software, not free utilities.

The only free EtherNet/IP explicit message tool I know about is the "OpENer" project, and that's an Adapter class object only. You need a client.

This has been asked before on this site so a search might yield some more options.

In particular, Molex has a free EtherNet/IP explicit message tool:

If all you want to do is some get/set service codes to various attributes, I think this will meet your needs.

Nice find, Robert ! Molex also resells IPScan, so that confused my search.

Thanks !

Thanks! I'll give it a try and report back.

I was able to use to get/set attribute single in a test environment with a single encoder.

On my machine network I cannot get it to work. I am seeing the following in the software (attachment). I cannot find any documentation for the software to figure out what the error code is.

When I zoom in I really can't read the error. Is this the same PC, using same nic to communicate to production network, as done with the test network? Do you have wireshark? Does the tool put frames out (I suspect not), but Wireshark would prove it? Look for tcp port 44818.

Same PC..

I figured out the problem. The Baumer manual has a continuing issue with identifying which parameters are given in decimal notation and which are given in hex. I converted my some values to hex and others to decimal and all is good.

They are apparently editing their manual now.
