9.8.3.9 Parameter trigger and start lock
Checking setpoints with parameter triggers
By setting the IPARAM input, the recipe phase informs the equipment phase that there are
new setpoints. This is the case prior to starting, when there is a change of control strategy or
after parameter changes when a phase is active. This gives the equipment phase the
opportunity of checking the setpoints and preventing the start with the start lock.
