The command to reset an output after a delay is:

1021,m,n,h,mn

1021: 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)

h: Delay off duration hours (0-21)

mn: Delay off duration minutes (0-59)

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).

Time schedule program

Time schedule programs relate to absolute daytimes. Up to 80 time schedule programs

can be stored in the SCOM-100 power fail safe memory, 10 programs for each day of a

week (Sunday to Saturday), and 10 programs for an ‘everyday’ schedule. Every

program permits up to 8 on switching sequences. The time based characteristic of a

schedule is shown in the following diagram:

1 2 ... 11 12 13 14 15 16 17 18 19 20 21 ... 39 40
