855t stack lights and sound for HMI alarms.

wanting to setup an allen bradley 855 amber stacklight and siren to go off when an alarm pops up on my Panelview 1000 HMI. not sure if it can ran off the HMI or do i have to tie them to the plc the HMI is communicating with? also some help with the logic in that case would help a lot.

thanks for the help.

They generally require 24VDC or 120VAC signals so you'll probably need to control them from the PLC.

Allen Bradley Stack lights aren't intelligent devices. As rupej indicated you provide them power just like any other light bulb. So you will need to have an output from a PLC drive them.
