Possible terminals for HART loops
B
Analog I/O module in slot B (availability depending on device version → 18)
C
Analog I/O module in slot C (availability depending on device version → 18)
E
HART Ex is output (available in all device versions)
HART devices must be configured and given a unique HART address in the range from
1 to 15 via their own user interface before they are connected to the Micropilot
NMR8x
. Make sure they are connected as defined by the terminal assignment
→ 28. Devices with an address larger than 15 are not recognized by the Micropilot.
Slot B or C: Setting the operating mode of the Analog I/O module
This section is not relevant for the HART Ex is output (Slot E). This output always
functions as a HART master for the connected HART slaves.
If HART devices are connected to an Analog I/O module (slot B or C in the terminal
compartment), this module must be configured as follows:
1. Navigate to the submenu of the respective Analog I/O module: Setup → Advanced
setup → Input/output → Analog I/O X1-3
2. Go to the
Operating mode
parameter (→ 138).
3. If only one HART device is connected to this loop:
Select the
HART 4..20mA input
option. In this case the 4-20mA signal can
be used in addition to the HART signal. For the configuration of the 4-20mA input:
4. If up to 6 HART devices are connected to this loop:
Select the
HART master
option.
3)
The current software does not support HART devices with adress 0 (zero).
