The MultiWrite tag allows you to configure a set of values that will be written to a list of registers when triggered. This can be used to place a plant into a state of operation or to quickly shut a plant down in one step.
Up to 100 output tags can be controlled by a single MultiWrite tag, with a defined value set to be written to each. The trigger for the write may be any of a manual button press, a tag that changes state from false to true, or an expression that evaluates to true.
Each value to be written will be checked to ensure that it is valid before it is written. Invalid writes will be ignored.
Should 100 tags not be enough, it is possible for one MultiWrite tag to trigger another upon finishing its write sequence.
An event will be recorded in the alarm history whenever a MultiWrite is triggered.
