Configuration
You can define the following settings for the analog inputs:
● Name: this name must be unique and cannot be used with any other input or output. The
factory defaults are AI1 to AI8.
● The unit for input feedback, e.g. liter (l) or kilogram (kg).
● Log this AI at a preset interval (Interval settings (Page 25))Hotspot-Text. The min. value
corresponds to the scaled value for 0 V. The max. value corresponds to the scaled value
for 10V.
● Lower limit.
● Upper limit.
● Min. change (hysteresis).
● If you activate "Send only user defined text", the module only sends the text defined in the
message box (no module name, IO name or timestamp).
● The analog inputs can send messages with values and units if:
– the upper + hysteresis limit is reached
– the lower - hysteresis limit is reached
– the status returns to a range between the upper and lower +/- hysteresis limits
Note
Min./max. and threshold/hysteresis values are limited to 5 digits with a maximum of 2
decimal places.
For every AI, a delay can be set (in the "Delay" box) with which it responds to status
changes. The UI LED flashes during the delay. A change is ignored if the input signal's
status changes back again before expiry of the set time.
Set the value 0 if you wish to deactivate this function.
Reading from an analog input
To query the status of an analog input, send the "ruin
number of the requested input.
The module responds with: „status AIn=xxxx"
If an input is assigned a special name, this input can be addressed by putting the name
between asterisks.
For example, the status of an input called 'Water tank' can be queried by sending the SMS
text "r*water tank*".
The module responds with: „status water tank=xxxx"
