Installing the Adapter
1. Set the adapter Node Address / Firmware Update switches (see
).
The Profibus Node Address/Firmware Update State is configurable
using an 8-bit DIP switch. The low seven bits set a node address and
the valid address allows binary coding of 1 through 125. A new node
address setting is recognized only when power is applied to the
adapter by power cycling the drive or after an adapter Reset Module
command. The MSB bit provides write access for the module flash
firmware update. In normal operating state, SW8 should be set to 1.

Jumper and Single/Multi-Drive Operation Jumper
Important: In normal operating state, SW8 should be set to 1.
