INSTALLATION
3.7.3.4 Modbus-RTU Read Coil (0x01)
Function code “Read Coil (0x01)” serves to read out all malfunction and maintenance
request messages from VISIC100SF.
Table 11: Read Coil Modbus-RTU
Example:
Read coil number 200 from slave (ID 101):
TX-> <65 01 00 C8 00 01 74 10>
RX-> <65 01 01 00 4E B8>
Maintenance request Vis = false
3.7.4 PROFIBUS DP-V0 (optional)
The PROFIBUS module belongs to the VISIC100SF when configured at the same time
during ordering. The VISIC100SF is integrated in the bus via a restart after wiring.
3.7.4.1 PROFIBUS addressing
The PROFIBUS-DP address of the device can be managed via the keypad.
For further information, see Section “Menu”, see “Setting the PROFIBUS address in “PB
ID””, page 57.
