8.5 Menu 75 Description
8.5.1 Expansion bus device P75.00
The hardware identifier is a read only value that indicates the type
of Expansion board bus fitted to the system. Valid values are:
4 Fieldbus Coupler.
This parameter is also viewable at P35.11.
8.5.2 Node Address P75.02
Each node attached to a PROFIBUS network needs to have a
defined unique node address.
Important: No PROFIBUS board may have the same node
address as another device connected to the same network.
When requested, the PROFIBUS board indicates its presence to
the bus master. If multiple boards are configured with the same
node address they will all try to respond at the same time.
For the PROFIBUS board the node address is defined by P75.02.
The node address may be any number between 2 and 126
inclusive. It is usual for the PROFIBUS master to take node
address 1, and for node address 127 to be reserved for multi-cast
messages.
The PROFIBUS node address can only be reconfigured once
per power up. If the node address needs changing, the new
node address must be programmed and then the drive power
cycled.
8.5.3 Protocol P75.03
Only the PROFIBUS-DP standard is supported, so this parameter
must be set to 3, other options are reserved for other Fieldbus
protocol standards.
