----------------------------------------------------
Please, remove both macros TEC (Trigger Event Code Name) and ACTV (Activate Event Code Invariant Delay)
from your trig.substitution file. (there is no more trigger event code name.
The forward/backward propagation and event code invariant delay is a default mode)
IOC engineer engineers need to put new macro SYS to describe the beam program in the trig.substitution file.substitutions and evr.substitutions files
Please, follow the following rule.
SYS=SYS0: LCLS
SYS=SYS1: FACET
SYS=SYS2: LCLS II
SYS=SYS6: NLCTA
Note)
If you really want to disable the event code invariant delay,
you can put ACTV macro and set it to ZERO.
Then the feature will be disabled. The intrinsic delay (EVG delay)
will be set to 13004 as a default.
If you want to change the default value, you can use TEC macro.
Please, put your default instrinsic delay value for the TEC macro.
