Hello,

Our customer had a modbus TCP/IP communication problem with PcVue.Their device is a gateway which can only accept max 5 tcp connections.

But every node in PcVue will launches a TCP connection. Please see the screenshots I made on my PC.

Sorry,, why I cannot upload pictures?

Who knows how to solve this issue?

I'm not sure but I think that you should use the adavnce option "sharing connevtion" in the Equipment configuration.

Hi,

Romain is right. The solution is using Sharing connection option and set one or many sharing group

Which web browser are you using? I also not able to upload images with Firefox. Consequently I am using Chrome to access the forum.
