The value must be written in a 15-bit scale (7FFFh = 32767)
2
to represent 100 % of the output desired
value, i.e.:
P0696 = 0000h (0 decimal)
→ analog output value = 0 %
P0696 = 7FFFh (32767 decimal)
→ analog output value = 100 %
The showed example was for P0696, but the same scale is also used for the parameters P0697. For instance,
to control the analog output 1 via serial, the following programming must be done:
Choose a parameter from P0696, P0697 to be the value used by the analog output 1. For this example, we
are going to select P0696.
Program the option “P0696 value” as the function for the analog output 1 in P0254.
Using the network interface, write in P0696 the desired value for the analog output 1, between 0 and 100
%, according to the parameter scale.
BACnet objects of the ANALOG OUTPUT type mold the analog outputs, where:
ANO0 - P0696.
ANO1 - P0697.
NOTE!
If the analog output is programmed for working from -10 V to 10 V, 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 -10 V to 10 V at the analog output.
P0760 – BACNET EQUIPMENT INSTANCE – HIGH PART
Range:
1 a 247
Default: 1
Properties:
CFG
Access groups via HMI:
NET
Description:
It defines the high part of the BACnet equipment instance.
NOTE!
Refer to the parameter P0761 description for more details.
P0761 – BACNET EQUIPMENT INSTANCE – LOW PART
Range:
0 to 9999
Default: 0
Properties:
CFG
Access groups via HMI:
NET
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.
