I/O and Hardware (M5)
Subnet mask (P5.9.1.4)
The network mask marks all the bits of an IP address for the identification of the network and the subnetwork.
Default gateway (P5.9.1.5)
Gateway address
is the IP address of a network point that acts as an entrance to another network.
MAC address (P5.9.1.6)
● MAC address (Media Access Control) is a unique address given to each network host.
● The MAC address of the control board.
BACnet IP Settings
Instance number (P 5.9.3.1.1)
Similar to BACnet MS/TP device object instance number (see Instance Number (P5.9.3.1.4).
Communication time-out (P5.9.3.1.2)
BACnet board initiates a communication error if the Ethernet connection is lost. Communication time-out
parameters define the minimum delay between UDP packages received from the master.
The timer is reset and started after each received UDP package. This parameter can be used if the master is
periodically polling the slaves.
Protocol in use (P5.9.3.1.3)
Use this parameter to enable and disable the BACnet/IP protocol.
● When the parameter value is set to 1, the BACnet/IP protocol is enabled.
● When the parameter value is set to 0, the BACnet/IP protocol is disabled.
IP Monitoring Values
Fieldbus protocol status (P5.9.3.2.1)
Fieldbus protocol status tells the status of the protocol.
Communication status (P5.9.3.2.2)
The Communication status displays how many error messages and how many good messages the variable
frequency drive has received. The Communication status includes a common error counter that counts CRC and
parity errors and a counter for good messages.
This parameter displays as
For example, 01.002 would represent one bad frame and two good messages.
Actual instance number (P5.9.3.2.3)
The Device Object's actual instance number. This monitoring value is needed when value 0 is written to Parameter
P5.9.3.1.1.
Control word (P5.9.3.2.3)
Displays the Control word received from the bus.
Status word (P5.9.3.2.4)
Displays the current Status word that is sent to the bus.
