alarm condition

[ngoodman]

I have a process variable called B3bz5pv and a set point called b3bz5sp I have created a variable offset called B3alarm max all as channels.

If i want to trip my alarm at set point + offset could i use in the alarm condition

B3bz5pv[0]>(b3bz5SP[0]+b3alarmmax[0]) ?

If not what can I use ?

Absolutely. Except you don't need [0] after variables, just channels. This is because variables typically don't have history. Unless you create an array with them explicitly, they are just scalars, so [0] is assumed. With channels, the history gets generated automatically, so [0] is needed to say you just want the most recent point.
