5 Configuration → Specifying the alarm monitoring
All module signals are defined as variables. Therefore, for the
entry activate the tab Variable definition in the configuration
program.
➡ In order to monitor a limit and to output a level on a digital output
when an alarm occurs, you can directly use the function of the
digital output. You do not need to set up any alarm monitoring.
The alarm monitoring is used to monitor signals in the module
and to make the result available to the PC or PLC as a precondi-
tioned signal. Checking the original signal in the PC or PLC can
the
refore be omitted.
Procedure 1. Click in the column Type of the first row (V1 = Variable 1) or
mark the row (click on V1) and use Variable definition >
Type.
2. Select Alarm.
3. Click in the column Variable name and allocate a name
iden-
tifying the alarm signal.
4. Click in the column Other and specif
y the type of alarm mon-
itoring.
You can specify up to four alarm conditions.
When one of the
conditions is satisfied, the alarm signal is triggered.
To the left above the graphical displays select the levels at
whic
h switching is to occur and how they are to switch. Enter
the values for the switching thresholds in the (scaled) unit of
the selected signal. Use either fixed values (constants) or
arrange for the values to be determined by other variables.
5. Click in the column Format/b
alance to specify the transfer
format.
Since the alarm signal, like digital signals, does not require
any
Decimal places, you can enter 0 here. 1 is sufficient for
the Field length.
When the dialog is closed, the number of transferred places
and the u
nit in the column Format/balance, e.g. f, are dis-
played.
6. Save the changes in a file and close the module once you have
made all the changes:
or File > Save to file and finish.
The file is created within the project folder and the file name
is genera
ted automatically. The project folder bears the same
name as the project. The generated file name contains the
address of the Test Controller through which the module is
connected and an identifier for the relevant module.
