SCOM-100, User guide 18

4.4.8 Clearing the digital output configuration

The command clears any output configurations related with multivibrator or time

schedules:

1090,m,n,ID

1090: 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)

4.5 Analog signal alarming

4.5.1 Analog input configuration

The SCOM-100 analog inputs can be configured to initiate alarm SMS messages when

preset alarm limit conditions (low & high alarm limits) are met. A user configurable

scale can be defined to associate an analog input signal to physical units. The

configuration command is:

1200,m,n,s,SSL,SSH,SCL,SCH,ALL,ALH,u,d

1200: Command ID

m: Module number (0 for SCOM-100 main unit, 1-4 for AI-4 expansion

units)

n: Input number (1-2 for SCOM-100 main unit, 1-4 for AI-4 expansion units)

s: Input signal name (Text: 0-15 characters, may include space characters)

SSL: Raw value reading for scale low (0-4095)

SSH: Raw value reading for scale high (0-4095)

SCL: Scale low in physical units (-100,000 to 100,000)

SCH: Scale high in physical units (-100,000 to 100,000)

ALL: Alarm low limit in physical units (Number in the range of SCL to SCH

with one optional decimal digit. Example: ALL = 52.3)

ALH: Alarm high limit in physical units (number in the range of SCL to SCH

with one optional decimal digit. Example: ALH = 121.5)

u: Physical unit (0-15 characters)

d: Delay time in seconds (0-65535)

For example let us explain all the different parameter settings to use a 4-20mA, 0-10

bar pressure sensor wired on analog input 2 on the main unit (See section 2.4.2).

The pressure sensor characteristic is shown in the diagram below:

1 2 ... 13 14 15 16 17 18 19 20 21 22 23 ... 39 40
