PLC network Variables vs OPC UA PubSub

I have an application requiring an exchange between 40 ctrlX at 500ms with 12 bytes of data from each. Under the circumstances is the prescribed method of data exchange PLC network variables or OPC-UA PubSub?

Re: PLC network Variables vs OPC UA PubSub

Hello Fouraker,

would be essential to go more in detail....
40 ctrlX communicate ... each of them to 39 partners telling differing data content? or telling broadcast/twittering-like to all the same?

Data needs to reach within 500ms , loss or delay not accepted?

in case the data is worse to hide and sensible, please email/send to contact.

Bye
