Dear Support Team, I am working on integrating a binary switching sensor connected to the AXL F EX IS AI8 HART XC 1F analog input module. The sensor operates on a two-wire loop-powered system , outputting 8 mA (Low State) and 16 mA (High State). Since the module includes both normal analog inputs and HART-specific inputs , I would like your guidance on the optimal configuration within PLCnext Engineer.
Key Considerations & Questions:
1. Best Input Selection & Processing:
* Should I use a HART input or a normal analog input for a binary switching sensor?
* If using a HART input (REAL data type required) , should I manually process the mA signal into a BOOL in PLC logic using a threshold (e.g., >12.0 mA = TRUE)?
* Does the AXL F EX IS AI8 module provide any built-in threshold or signal processing functions to automatically convert an analog (mA) signal into a binary state?
1. MTP Designer Integration:
* Since the sensor functions as a binary switch , should I use a BINMON block instead of ANAMON in MTP Designer?
* Will this impact how the data is mapped or visualized in the PLC or HMI?
I would appreciate any guidance, or relevant documentation to help configure this setup correctly in PLCnext Engineer.
Looking forward to your support.
Best regards,
SHNB
Inquiry Regarding Analog Module (AXL F EX IS AI8 HART XC 1F) Configuration for Binary Switching Sens
Hello SHNB,
I can say the following about the first point:
For HART sensors, the HART inputs must be used.
Otherwise the normal analog inputs are used.
The MTP standard describes 2 interfaces for the binary sensors: BinView and BinMon. BinView covers most cases.
BinMon have some additional flutter detection functionality.
For this type of interface a special modelling will be created. And also this are different visual objects.
