3 Functions
Parameter P0725 is used to define as to whether digital inputs DIN1 - DIN6 are
logical "1" when appropriately connected to 0 V or 24 V. The logical states of the
digital inputs can be de-bounced using P0724 and read-out using parameter r0722
(BICO monitoring parameter). Further, this parameter is used to parameterize
BICO for the digital inputs (refer to BICO parameterization in the following Section).
P0701 – P0706 (digital inputs 1–6) or P0707 – P0708 (analog inputs 1-2)
The possible settings of the individual inputs are listed in Table 3-11.

Example:
An ON/OFF1 command should be realized using digital input DIN1.
P0700 = 2
P0701 = 1
NOTE
If an analog input (refer to Fig. 3-33) has been configured as digital input, then the
following limit values apply:
