Omron IO server config with NX1P2 plc

Jcadorette · January 8, 2018, 1:34pm

Hello there,

One of my customer is having issue configurating his NX1P2 Omron PLC with a IO Server FINS configuration. He is trying to define tad adresses.

Please also see pdf document that shows the whole config.NX1P2_eWON_server_issues_Riley.pdf (985.0 KB)

Here is the issue:

I’m using an OMRON NX1P2 controller, rather than a CS/CJ PLC as outlined in that document. The software programming is done in OMRON’s Sysmac Studio software, rather than CX-Programmer, and tags defined in Sysmac Studio don’t use the same tag address convention as the one outlined in that document.
Is there any chance you have information that’s specific to using the eWON with an NX or NJ series controller? Those use a combination of Sysmac Studio and Omron’s Network Configurator tool to set up Ethernet/IP communication, as far as I can tell.

Thanks for your help!

@Jcadorette

Currently it is not possible to poll data from an NX PLC via an eWON.

My colleague in Nivelles is interested in testing a possible step that may allow the polling to
work. Would your customer be willing to provide a temporary set of credentials for my colleague to log in with?

HI @jseanor, sure i will ask him and let you know.

PS: My colleague Denis Kaliberov sent a ticket that have the same topic, can you join both tickets together?

Thanks,

@Jcadorette

Excellent also I did search for Denis but it doesn’t appear he actually submitted a thread.

@Jcadorette

UPDATE: We just found the thread he created on our other system. I am importing it here and inviting Denis to this thread.

Hello,

One of our client is using the NX1P2 OMRON controller. The software programming is done in OMRON’s Sysmac Studio software and tags defined in Sysmac Studio.

Is there any chance you have information that’s specific to using the eWON with an NX series controller?

Those use a combination of Sysmac Studio and Omron’s Network Configurator tool to set up Ethernet/IP communication, as far as I can tell.

Thank you.

Have a good day!

I have merged your request with @Jcadorette and have invited you to be a participant on this thread.

Hi @jseanor,

Check your messages, the credentials to log in are there.

Thx,

jseanor · January 9, 2018, 2:06pm

@Jcadorette

Excellent. I will send this information over.

I cannot guarantee we will be able to make it work however there are a few things we can
test on our end.

Jcadorette · January 9, 2018, 2:20pm

Thanks @jseanor

Do you know why it’s not possible to poll from an NX while it is from a NJ?

For the back-up, i will ask customer and get back to you.

Thanks,

@Jcadorette

The NX series PLC does not support the FINS protocol, primarily FINS TCP anymore. Usually with an eWON we use FINS TCP to poll data which the NJ device does support.

One thing my colleague however would like to determine is he may have seen somewhere support for FINS UDP which may allow us to make it work though until we can fully test we cannot be certain.

@Jcadorette

We made some changes in the Flexy and it appears the data is polling though we cannot be certain because we cannot change tag values. Can you try updating a value for me and advise if the polling is working?

Jcadorette · January 10, 2018, 2:21pm

Hi Jordan,

Here’s the backup. Customer sent me more than needed so we should be ok to test it.

He also mentionned that the unit is on test, sitting on his deck so no problem to change some parameters, it’s not live.

He also mentionned this:

''From my research into this a bit, it seems like the NX1P2 may not support FINS over ethernet/IP. It does, however, seem to support FINS over serial communication (where I can get a RS232C or RS422/485 extension card for the NX) . I believe the eWON Flexy has serial extension cards, perhaps the answer could be in using serial communication for the tag links and datalogging, with the LAN network for remote connectivity?

Let me know what you think about investigating that route.’’

Can we test this alternative to pass by Serial communication to make it work?

Thanking you in advance!

Best Regards,

PLC Backup moved to internal

@Jcadorette

Were you able to have your customer test updating some values to see if the ViewIO screen updated to reflect the changes?

Jcadorette · January 12, 2018, 9:22pm

Hi Jordan,

Everything works fine!! We would like to know what your team did because there will be a repeat for sure.

Thanks for your help!

anynotes on how this was done? Trying to set this up as well, ewon flexi to NX1P2

jseanor · January 18, 2018, 3:05pm

@dothat44

The only thing we needed to do was update the Flexy from FINS TCP to use FINS UDP.
The NX1 devices do not support FINS TCP currently though they do support FINS UDP.
