Frequency (Whenever, From, When, Every) - Siemens SINUMERIK 840D sl Function Manual

Identification number ID/IDS
Range of values
The identification numbers ID/IDS are in various number ranges. The number ranges are
assigned to different users.
Parallelization
If several synchronized actions are to be active in parallel in a channel, their identification
numbers ID/IDS must be different. Synchronized actions with the same identification number
replace each other within a channel.
Sequence of execution
Modal and static synchronized actions are executed in the order of their identification numbers
ID/IDS.
Non-modal synchronized actions are executed after execution of the modal synchronized
actions in the order of their programming.
Coordination via part programs and synchronized actions
Synchronized actions can be coordinated via part programs and synchronized actions based
on the identification numbers ID/IDS (see Section "Coordination via part program and
synchronized action (LOCK, UNLOCK, CANCEL) (Page 122)").
Coordination via PLC
Synchronized actions with identification numbers ID/IDS in the range from 1 to 64 can be
coordinated via the NC/PLC interface from the PLC user program (see Section "Coordination
via PLC (Page 123)").
3.2.2

Frequency (WHENEVER, FROM, WHEN, EVERY)

The frequency specifies how often the condition is queried and, when the condition is fulfilled,
how often the action should be executed. The frequency is part of the condition.
Frequency Meaning
--- If no frequency is specified, the action is executed cyclically in every interpolator clock cycle.
1)
If the condition is fulfilled, the action is executed cyclically in every interpolator clock cycle.
WHENEVER
After the condition has been fulfilled once, the action is executed cyclically in every interpolator clock
FROM
cycle for as long as the synchronized action is active.
