Code Modbus ID Parameter Application RO/RW
P12.3.2.2 584 Baud Rate 1,2,3 RW
Use this parameter set communication speed for RS-485 communication.
P12.3.2.3 585 Parity Type 1,2,3 RW
Use this parameter set parity type for RS-485 communication.
P12.3.2.4 588 Modbus RTU Protocol Status 1,2,3 RO
Use this parameter to show the protocol status for RS-485 communication.
0 = Initial
1 = Stopped
2 = Operational
3 = Faulted
P12.3.2.5 593 Comm Timeout Modbus RTU 1,2,3 RW
Use this parameter to set the time it waits before a communication fault occurs over Modbus RTU if a
message isn't received.
P12.3.2.6 2516 Modbus RTU Fault Response 1,2,3 RW
Use this parameter to set the the Fieldbus Fault condition for Modbus RTU Communication.
0 = Only in Fieldbus Control Mode - when Fieldbus is the control place and Fieldbus fault is active drive
will fault on loss of coms, if not in Fieldbus Control place will not fault.
1 = In all Control Modes - no matter the control place setting if communication is lost Fieldbus fault
response will occur.
P12.3.3.1 594 MSTP Baud Rate 1,2,3 RW
Use this parameter to set the communication speed over BACnet.
P12.3.3.2 595 MSTP Device Address 1,2,3 RW
Use this parameter to set the BACnet Address that the drive will be located at on Instance node.
P12.3.3.3 596 MSTP Instance Number 1,2,3 RW
Use this parameter to set the the BACnet Instance value.
P12.3.3.4 598 MSTP Comm Timeout 1,2,3 RW
Use this parameter to set the time it waits before a communication fault occurs over BACnet.
P12.3.3.5 599 MSTP Protocol Status 1,2,3 RO
Use this parameter to see the status of the BACnet Protocol.
P12.3.3.6 600 MSTP Fault Code 1,2,3 RO
Use this parameter to see the status of the BACnet Protocol faults
0 = None
1 = Sole Master
P12.3.3.7 2526 MSTP Fault Response 1,2,3 RW
Use this parameter to set the Fieldbus Fault condition for Modbus RTU and BACnet Communication.
0 = Only in Fieldbus Control Mode - when fieldbus is the control place and Fieldbus fault is active drive
will fault on loss of coms, if not in Fieldbus Control place will not fault.
1 = In all Control Modes - no matter the control place setting if communication is lost Fieldbus fault
response will occur.
P12.3.3.8 1537 MSTP Max Master 1,2,3 RW
Use this parameter to set the maximum number of devices used on the network. This will prevent
additional traffic scanning on the network.
P12.3.4.1 1727 SA Bus Baud Rate 1,2,3 RW
Select the communication speed for the network.
P12.3.4.2 1726 SA Bus Device Address 1,2,3 RW
The address of the device on the network. Each device to have unique address in the network.
P12.3.4.3 1728 SA Bus Instance Number 1,2,3 RW
The Device Object’s Instance number is used in conjunction with the MAC address to assign the devices
on the network. The instance number can have up to 127 nodes on it before a different instance number
is required.
