11.21.13 Building automation interface
The ID code for the building automation interface is 402.
Pr 17.02 and Pr 17.51 display the firmware version in the form xx.yy.zz,
where xx.yy is Pr 17.02 and zz is Pr 17.51.
If a MAC address is selected that is greater than or less than those
allowed by the currently selected protocol, then the actual address used
will be the maximum valid address value.
This selects the baud rate used for network communication.
The default value when Pr 17.04 is set to 0 OR >8 is as follows:
This selects the protocol used for the building automation network as
follows:
If a value greater than 3 is entered for Pr 17.05 then the building
automation network is disabled.
This parameter displays the number of valid messages that have been
received using the currently selected building automation protocol. If the
communications settings are configured correctly then this counter will
count each time a message is received, therefore if the value remains
constant then there is likely to be an error in either the configuration or
the wiring to the communications port.
The received message counter is reset to in the following circumstances:
1. When another message is received after 9999 prior valid messages
have been received
2. Upon power up
BACnet use only
This is highest address that the drive will use when looking for the next
master on the network with which token passing can be achieved.
If a value greater than 127 is entered then the value used will be 127.
The parameter value will change to 127 to reflect this.
BACnet use only
If Object Identifier is set to any value less than -19 (to -32768) then the
Pr 17.10 gets set to 1. If Object Identifier is set to zero then the MAC/
Node address selected in Pr 17.03 will be used as the object identifier
for the BACnet device; otherwise the device object identifier will be the
value specified here.
The BACnet Object Identifier range supported on Affinity drive is from 1
to 4194302 (supported on BAN firmware V01.03.07 or later). In order to
set the Object Identifier above 32767 two consecutive menu 18
parameters are used as shown in Table 11-11 on page 226. Each pair of
menu 18 parameters is selected using Pr 17.10; the lower parameter
number will contain the last four decimal digits of the Object Identifier
and the higher parameter number will contain the first three decimal
digits of the Object Identifier. The choice of which pair of parameters is
used depends on the availability of the parameters, as long as they are
NOT used by any on board PLC or DPL program they can be used.
