EFB PROTOCOL ID
Contains the identification and
program revision of the
protocol.
Do not edit. Any non-zero value entered for parameter 9802
COMM PROT SEL, sets this parameter automatically. The
format is: XXYY, where xx = protocol ID, and YY = program
revision.
5302
EFB STATION ID
Defines the node address of
the RS485 link.
When one of these protocols is
selected, the default value for
this parameter is: 1
When this protocol is
selected, the default
value for this parameter
is: 128
Set each drive on the network with a unique value for this
parameter.
Note:
For a new address to take affect, the drive power
must be cycled
OR
5302 must first be set to 0 before
selecting a new address. Leaving 5302 = 0 places the
RS485 channel in reset, disabling communication.
Note:
For the BACnet protocoln , the ACH550 will function as a Master with MAC
IDs in the range of 1 - 127. With MAC ID settings of 128 - 254, the drive is in Slave
only behavior.
