Detailed description
2.1 Components of synchronized actions
No data
Synchronized actions that have no specified validity have a non-modal action, i.e. they apply
only to the next block.
Non-modal synchronized actions are operative only in AUTOMATIC mode.
From SW 6.1 and later, non-modal synchronized actions are active modally for all
preprocessing stop blocks (incl. implicitly generated ones) and for implicitly generated
intermediate blocks.
ID
Synchronized actions with validity identifier ID act modally in the subsequently programmed
blocks. They are operative only in AUTOMATIC mode.
Limitation:
• ID actions remain operative only until another synchronized action with the same
• till deletion, CANCEL(i), see Chapter "Coordinations between synchronized actions,
IDS
Statically effective synchronized actions that are programmed with the keyword "IDS", are
active in all operating modes. They are also referred to as static synchronized actions.
Option.
Synchronized actions programmed with ID or IDS are deleted from the part program.
Identification numbers
For modal synchronized actions (ID, IDS) identification numbers between 1 and 255 are
allocated. They are important for the functions of mutual coordination of synchronized
actions. See Chapter "Coordination of synchronized actions, technology cycles, part program
(and PLC)".
Modal/static synchronized actions with identification numbers between 1 and 64 can be
disabled and enabled from the PLC. See Chapter "Control via PLC".
Unique identification numbers must be allocated in the channel.
Applications for static synchronized actions:
• AC-grinding also active in the JOG mode
• Logic operations for Safety Integrated
• Monitoring functions, responses to machine states in all modes
• Ooptimization of the tool change
• Cyclic machines
Examples:
IDS=1 EVERY $A_IN[1]==1 DO POS[X]=100: all modes
ID=2 EVERY $A_IN[1]==0 DO POS[X]=0: AUTOMATIC
