Specifications are subject to change without notice WM30 96 DS 071020

WM30 96

Protocol

Profibus DP V0 slave

Baudrate

9.6 k to 12 Mbps (9.6,

19.2, 45.45, 93.75, 187.5,

or 500 kbps; 1.5, 3, 6, or

12 Mbps)

Note

With the rotary switch

(on the back of the basic

unit) in lock position

the modification of the

programming parameters

and the reset command

by means of the serial

communication is not

allowed. In this case just

the data reading is allowed.

Insulation
