11.3.1 General
The micro-switch can be used for several functions. The function it triggers may be depending on the present field
bus. Use the micro-switch always in combination with the LED’s to prevent errors. The following functions can be
triggered with the micro-switch.
• Set instrument to default installation address/MAC-ID
• Read bus-address/MAC-ID and baud rate
• Change bus-address/MAC-ID and baud rate
• Read control mode
• Change control mode
To read or change settings by the micro-switch and LED’s, the number
can be separated in “tens” and “units”. The “tens” is the most left part
of the number. The “unit” is the most right decimal of the number.
The easiest way to set an address / baud rate is by using the rotary switches on the instrument (if
present). Remember that the rotary switch setting overrides software setting at start-up if the switches
are not in the soft-address position.
