•
Rising / Falling flank message
•
Send only the user defined text, this sends only the text defined in the message box, no module name,
IO name and timestamp.
•
Rising / Falling flank message delay: the changed status must be held for the given time before being
accepted
In the following examples all Di’s are connected to be pulled

GSM-PRO-8AI
The 8AI has 8 analog inputs. Each analog input (AI) represents a scaled value from 0 to 100% (10V or 20mA).
Within this scale threshold values can be monitored.
10.4.1
Configuration
Configure the following items:
•
Name; default set as AI1 to AI8.
•
Input type: voltage, current or temperature
•
The unit for the input feedback. E.g. litres (Ltr) or kilograms (kg).
•
Offset: Calibrate the input value, e.g. temperature measurement with longer cables
•
Log this AI at a pre-set interval, see for interval settings.
•
The min. value represents the scaled value for 0V
•
The max. value represents the scaled value for 10V or 20mA
•
Lower limit threshold
•
Upper limit threshold
•
Minimal change (hysteresis)
•
Send only the user defined text, this sends only the text defined in the message box, no module name,
IO name and timestamp.
•
The Analog Inputs can generate messages including value and unit when:
-
The upper limit + hysteresis is reached
-
The lower limit
–
hysteresis is reached
-
The status recovers between the upper and lower limit +/- hysteresis
NOTE
:
The min./max. and threshold/hysteresis values are limited to 5 digits with a maximum of 2 decimals.
A delay in seconds can be set which a changed AI has to exceed before it is accepted, during the delay the UI
led blinks. If the status of the delay is changed back again to the previous state before the delay is expired the
change is discarded.
Clear the delay to disable detection delay.
