Infinite Peripherals SCOM-100 - Manual (Page 12)

SCOM-100, User guide 12
a: Transition selection (0: No alarm, 1: positive 2: negative 3: both
transitions)
d: Delay time in seconds (0-65535)
The following example illustrates how to configure digital input 1 to initiate an alarm
SMS after any signal transition, a delay time of 30 seconds and a signal name
configured to “Door contact”.
The configuration command would be:
1100,0,1,Door contact,3,30
Send an SMS to the SCOM-100 unit with the respective command.
Connect a contact or a loop wire to digital input 1 according to the wiring diagram in
section 2.2. Close the contact/loop and leave it closed for more than 30 seconds. The
S/R SMS LED will blink and you will receive an alarm SMS message and the following
contents:
My SCOM-100
Door contact
POSITIVE ALARM
Now open the input contact/loop for 30 seconds. You will receive an alarm SMS
message with the following contents:
My SCOM-100
Door contact
NEGATIVE ALARM
If you close or open the contact without maintaining a delay time of 30 seconds, you
won’t receive any alarm SMS message.
4.3.1 Setting alarm message texts
You can set up to 128 custom text messages to be announced in an SMS alarm as a
descriptive reason instead of the default causal text (e.g. POSITIVE ALARM).
The command to configure a text message is:
0630,ID,s
0630: Command ID
ID: Message ID (1-128)
s: Message text (0-31 characters, may include space characters)
The command to associate a text message to an output at a signal transition is:
1101,m,n,ID1,ID2
1101: Command ID
m: Module number (0 for SCOM-100 main unit, 1-8 for DI-42 I/O expansion
units)
n: Input number (1-4)
ID1: ID number 0-128 of the message’s text for the negative transition (1 to 0)
ID2: ID number 0-128 of the message’s text for the positive transition (0 to 1)
Note: ID1/ID2 value 0 indicate the default message.
Let us specify alarm text messages for the previous example. The message for the
positive (0 to 1) transition should be ‘Door is opened’. The respective message for the
negative transition should be ‘Door is closed’.
The commands to configure these text messages are:
