analog inputs and outputs configured for voltage signal 0...10 V.
NOTE!
To be able to use the analog input and/or output as current signals, it is
necessary to change the switch S1 and the related parameters as per
. In order to set the analog inputs to bipolar voltage signal
(-10…10 V), it is necessary to set P0233 and P0238 according to
. Refer to the CFW700 programming manual for more information.

NOTE!
Settings of the S2 switch:
S2.1 = ON and S2.2 = ON: RS-485 is ON.
S2.1 = OFF and S2.2 = OFF: RS-485 is OFF.
The factory default for the S2.1 and S2.2 switches are OFF.
Other combinations of switch S2 are not allowed.
