4.4.7 Digital output time based scheduling
Multivibrator
A multivibrator is a continuous time based switching
sequence as shown in the following diagram:
Although the output’s switching is continuous, commands
for temporary setting or resetting (1000, 1001) are also
applicable and accepted by the device. The command to
set a digital output as a multivibrator is:
1040,m,n,mon,moff
1040: Command ID
m: Module number (0 for SCOM-100 main
unit, 1-8 for DI-42 I/O expansion units)
n: Output number (1-4 for SCOM-100
main unit, 1-2 for DI-42 I/O expansion
units)
mon: On duration in minutes (1-1320)
moff: Off duration minutes (1-1320)
The ‘Clear DO configuration’ command can be used to
remove the multivibrator configuration from an output
(see 4.4.8).
