Hi! I'm currently working on an ignition project where we want to create a trigger for a concrete type of machine in a line. The machine is defined by a parametrized UDT and my question is: Is there any way to create a parametrized transaction group so i can re-use a trigger for multiple machines of a line which are identically the same not having to replicate the same trigger but pointing to different tags? This is a very tedious work and difficults mantainability and failure risk when pointing to a new machine. Regards, Jorge ---

Not in a transaction group, no. Consider using a gateway tag change event script to replicate the action. ---

As i've read, tag change events are for running scripts, but, the transaction group trigger performs an insert, so, is there any way i can call the trigger and pass to it some arguments (references to tag)?, or you suggest to make data insertion on the script itself and not using transaction group? ---

Nice! Thanks I'll check it, hope it works for me
