Synchronizing argument
This is a brief description of the arguments used by move instructions to facilitate the
synchronization between tasks. For more information, see any move instruction in Technical
reference manual - RAPID Instructions, Functions and Data types.
Argument Description
ID All move instructions executed between the SyncMoveOn and SyncMoveOff
instructions must have the argument ID specified. The ID argument must be
the same for all the move instructions (in each task program) that should
execute simultaneously.
The ID argument can be a numeric value or a syncident variable.
The purpose of ID is to support the operator by making it easier to see which
move instructions that are synchronized with each other. Make sure an ID
value is not used for more than one move instruction, between the same
SyncMoveOn and SyncMoveOff instructions. It is also helpful for the
operator if the ID values are ascending for consecutive move instructions
(e.g. 10, 20, 30, ...).
Move instructions that are not between the SyncMoveOn and SyncMoveOff
instructions must not have the argument ID.
