SRD991 with PROFIBUS PA—Menu 10: Bus Address
M 1 2 3 4
½ - - ½ ½ M, LED 3 and LED 4 flash
Here the bus address of the SRD can be indicated and changed. The bus
address is in the value range of 0 to 127; for the display 7 bits are required.
Each bit has a specific value (bit 1=1, bit 2=2, bit 3=4, bit 4=8, bit 5=16, bit
6=32, bit 7=64). The bus address is then the total of the individual values.
To display this with 4 LEDs, selection must be made between the lower
and upper 4 bits (whereby the highest bit 8 has no usage and is always 0).
10.1 Selection of lower 4 bits:
¼ ¾ - - - M short flash, LED 1 long flash
With UP or DOWN key to selection of upper 4 bits:
10.2 Selection of upper 4 bits:
¼ - - - ¾ M short flash, LED 4 long flash
Upon selection, the bits are displayed. When pressing UP or DOWN keys,
the value is always changed by 1. Pressing keys UP+DOWN, the newly
entered address will be activated.
The bus address is the total of the individual values:
Values of the lower 4 bits and the upper 4 bits:
– [1] [2] [4] [8] Value of the bits – [16] [32] [64] – Value of the bits

Note: Addresses 0 and 127 should not be used. Address 126 (delivery condi-
tion) is not permitted for cyclical operation.
For further information see TI EVE0105 P.
In the version with LCD indicator, the address is displayed in decimal and
hexadecimal number system.
10.3 Address
With LCD indicator, this function is recommended, whereby the address
can be completely entered, without separation in LSB and MSB.
The keys have Autorepeat: By pressing and holding of a key UP or DOWN,
the value is counted upward, after some time in larger steps.
