Example: Implementing multiple calls of a macro via a loop
INFORMATION
When macros are recorded on the
Controller macros
tab in PIMikroMove, the
MAC BEG
and
MAC END
commands must be left out.
The TESTDION macro checks the status of the digital input lines on the
I/O
socket. It uses a local
variable to identify the digital input line (1 to 4). So that the TESTDION macro does not have to
be called separately for each input line, another macro with a loop is recorded.
➢
Record the LOOPDION macro by sending:
MAC BEG loopdion
VAR COUNTER 1
MAC START TESTDION ${COUNTER}
ADD COUNTER ${COUNTER} 1
JRC -2 VAR? COUNTER < 5
MAC END
The COUNTER variable is created with the value 1. After this, the TESTDION macro is
started for the input line whose identifier is specified via the COUNTER variable. Then
the value of the COUNTER is increased by 1. As long as the value of the COUNTER is less
than 5, the macro execution pointer subsequently jumps two lines back, so that the
TESTDION is now started for the next digital input line.
Stopping a macro
INFORMATION
You can link the stopping of the macro execution to a condition with the
MEX
command. The
command must be included in the macro.
In the following, PITerminal or the
Command entry
window of PIMikroMove is used to enter
commands. Details on working with the
Controller macros
tab in PIMikroMove are in the
PIMikroMove manual.
➢
Stop the macro execution with the
#24
or
STP
commands.
➢
If you want to check whether an error has occurred during macro execution, send the
MAC ERR?
command. The response shows the last error that occurred.
