CONFIGURATION OF PARAMETERS FOR SERIAL COMMUNICATION
Two parameters must be configured for using the serial type:
bavd
: Communication speed.
addr
: Communication address for the controller.
REDUCED REGISTERS TABLE
FOR SERIAL COMMUNICATION
Communication Protocol
The MOSBUS RTU slave is implemented. All configurable
parameters can be accessed for reading or writing through the
communication port. Broadcast commands are supported as well
(address 0).
The available Modbus commands are:
03 -
Read Holding Register
06 -
Preset Single Register
05 -
Force Single Coil
Holding Registers Table
Follows a description of the usual communication registers. For full
documentation download the Registers Table for Serial
Communication in the N1040 section of our website –
www.novusautomation.com
.
All registers are 16 bit signed integers.
Address Parameter
Register Description
0000
Active SP Read: Active control SP (main SP, from
ramp and soak or from remote SP).
Write: To main SP.
Range: from
spll
to
spkl
.
0001
PV
Read: Process Variable.
Write: Not allowed.
Range: Minimum value is the one
configured in
spll
and the maximum
value is the one configured in
spkl
.
Decimal point position depends on
dppo
value.
In case of temperature reading, the value
read is always multiplied by 10,
independently of
dppo
value.
0002
MV
Read: Output Power in automatic or
manual mode.
Write: Not allowed. See address 29.
Range: 0 to 1000 (0.0 to 100.0 %).
