NOTE!
If the analog output is programmed for working from -10V to 10V, negative values for this parameter
must be used to command the output with negative voltage values, i.e., -32768 to 32767 represent a
variation from -10V to 10V at the analog output.

113 Serial RS232 / 485
Description:
It defines the low part of the BACnet equipment instance.
The BACnet standard defines that the equipment instance must be unique in the network and it must present a
value between 0 and 4194304. The BACnet instance will compose the Object Identifier property of the DEVICE
object, which defines the equipment characteristics in the network.
The BACnet instance can be defined automatically or manually:
Automatically:
If the values of parameters P0760 and P0761 are set 0 (default value), the inverter will automatically create the
BACnet instance based on the vendor BACnet ID (WEG BACnet ID = 359) and the serial address. For this
configuration, the user must only inform the serial address at the parameter P0308.
BACnet instance = BACnet ID + Serial address
Example 1: serial address = 102
Instance = 359102
Example 2: serial address = 15
Instance = 359015
NOTE!
The instance created automatically is not showed at the parameters P0760 and P0761, which remain
with the value 0.
