Title: EthernetIPforSLCMicroCom Multiple Computer Access
Post by: PoppaDollz on May 21, 2021, 01:21:57 PM

Hello,

I have created a dashboard of various metrics that my coordinators post in a production report every hour.

We are pulling data off of a Micrologix 1200 microcontroller through a 1761-NET-ENI ethernet device.

I am utilizing the EthernetIPforSLCMicroCom driver to pull the data into a Visual Studio VB.net program.

The issue I'm facing is that it appears only one person can have a program open that receives live data.

If I have the program running on my computer and my coordinator tries to open it up, all of the data that is shown with the various AdvancedHMI control components will not update until I exit out of it on my computer.

I'm not sure if this is a limitation of my hardware, but is there a way that we can both access the data simultaneously on our computers?

Any and all help is greatly appreciated

I know there are issues with the ENI module running out of connections. They tend not to release connections if not properly disconnected and you have to cycle power to restore all the available connections.

I think you only get 5. Some things will suck up more than 1. I think Archie is correct, that's your problem.
