PLU data not passing to Slave Station

I noticed my STOCK COUNTS didn't get sent over with this method, is there some other function to do this?

I tried the SEND STOCK COUNTER but once I press the button the system just sits and does nothing until I exit out to another screen?

Quirky system but after exiting and going to HOME screen on both systems the stock did match up....I'm def learning as I go

also it would be worth turning on the auto irc initialise in program 3 , system programming, system flags, IRC Control.

then any time that there is a power cut or one gets turned off and on it re establishes the network topology

That would definitely make sense, should this be set on both tills or master only?

Both tills.

Thank you very much for everyone's advice
