System Interfaces

MODBUS Communciation

The controller can be accessed over MODBUS TCP/IP to

remotely activate maintenance mode. If maintenance mode

is activated over MODBUS, it works the same as if the switch

was turned on.

The default IP address of the controller is 192.168.0.74 but

can be specified at the time of ordering. For the controller,

the next address would be 192.168.0.76 followed by

192.168.0.78. The increase of 2 on the address is due to the

gateway filling in between these values.

In order to activate DAS over MODBUS, you will need a

MODBUS program. Siemens has a program called Sm@rt DAS

MODBUS Communication Module that can be used to read

and write settings for Windows 7 and later.

For full MODBUS functionality see Section 4, Communications
