The delay time is entered in milliseconds - but is rounded-off to a multiple of the interpolator
cycles p0115[5]. The minimum delay time is one interpolation cycle; this means that if a
delay time is parameterized which is less than an interpolation cycle, then the system waits
for one interpolation cycle.
Example:
Waiting time: 9 ms
Interpolation cycle: 4 ms
Active waiting time: 12 ms
Regardless of the parameterized continuation condition which is parameterized for the task
that precedes the WAIT task, an exact stop is always executed before the waiting time
expires. The WAIT task can be executed by an external block change.
Possible continuation conditions include END, CONTINUE_WITH_STOP,
CONTINUE_EXTERNAL, CONTINUE_EXTERNAL_WAIT, and
CONTINUE_EXTERNAL_ALARM. The fault message is triggered when "External block
change" has still not been issued after the waiting time has elapsed.
GOTO
Using the GOTO task, jumps can be executed within a sequence of traversing tasks. The
block number which is to be jumped to must be specified as task parameter. A continuation
condition is not permissible. If there is a block with this number, then alarm A07468 (jump
destination does not exist in traversing block x) is output and the block is designated as
being inconsistent.
The following parameters are relevant:
● p2616[x] Block number
● p2622[x] Task parameter = Next traversing block number
Any two of the SET_O, RESET_O and GOTO tasks can be processed in an interpolation
cycle and a subsequent POSITION and WAIT task can be started.
SET_O, RESET_O
The tasks SET_O and RESET_O allow up to two binary signals (output 1 or 2) to be
simultaneously set or reset. The number of the output (1 or 2) is specified bit-coded in the
task parameter.
The following parameters are relevant:
● p2616[x] Block number
● p2622[x] Task parameter = bit-coded output:
Possible continuation conditions are END, CONTINUE_ON-THE-FLY and
CONTINUE_WITH_STOP, and CONTINUE_EXTERNAL_WAIT.
The binary signals (r2683.10 (output 1) or r2683.11 (output 2)) can be assigned to digital
outputs. The assignment in STARTER is made using the "Configuration digital output"
button.
