4-4 PROFIBUS Communications Module
4.4 Setting the Node Address
The PROFIBUS Node address/Firmware Update State is set
through the use of an 8-bit DIP switch. The low seven bits let you set
a node address and the valid address allows binary coding 1
through 125. New settings of node address are recognized only
when power is applied to the module, cycle power, or a 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.
Refer to section 3.2, Commissioning the Module, for more
information.
