Max devices Modbus TCP driver

Ignition
1

Hello,

How many devices of Modbus TCP drivers can be created?

Can I have 77 modbus TCP devices(I will read around 260 tags from each PLC (20.000 OPC tags in total))?

In the project I have around 160.000 tags( Memory tags, expression tags, OPC tags…)

I am using Ignition 7.9.7 (64 bit)

Thank you very much!

Yes, no problem.

There's no intentional limit to the number of devices, but the current design probably makes the practical limit somewhere around a couple thousand.

Hi!,

When you say “a couple thousand” did you refers to “devices” or “OPC tags”?

Thank you!
