Operational instructions for digital multibus instruments
9.17.023
11.3.2 Readout bus-address/MAC-ID and baudrate:
Pressing the switch 3x briefly with intervals of max. 1 second in normal running/operation mode will trigger the
instrument to “show” its bus address/MAC-ID and baud rate. For indication the bus-address/MAC-ID the green LED
will flash the amount of tens and the red LED the amount of units in the number. For indication of baud rate setting,
both LED’s will flash. The flashes are called “count-flashes” and have a pattern of 0.5 sec. on, 0.5 sec. off.

Examples:
• For bus address/MAC-ID 35 the green LED will flash 3 times and the red LED will flash 5 times.
• For bus address/MAC-ID 20 the green LED will flash 2 times and the red LED will flash 0 times.
• For bus address/MAC-ID 3 the green LED will flash 0 times and the red LED will flash 3 times.
• For bus address 126 the green LED will flash 12 times and the red LED will flash 6 times.

*MBC3 type instruments have additional baud rates available for the several field busses.
EtherCAT bus address is always ‘0’.
Examples:
• For PROFIBUS-DP baud rate readout of 12000000 Baud, both LED’s will flash 10 times.
• For DeviceNet baud rate readout of 250000 Baud, both LED’s will flash 2 times.
