Ignition
1

In UDT, I would like to be able to have opc item path with expression with multiplication and more than 1 operator :

For example :
{{byteStart+1}+{offset*2}}

By combining “*”, “+” and “-” we were able to create rules for calculate modbus ou S7 address

That's clear but..
is there any way to use more complicated expressions like in alarms, where u have options to use string functions (split, right etc.) in expressions?
I want to get substring from name or InstanceName, is this possible? Or why not?

Best regards
