72 Binary inputs
5-30
In the basic version of the unit, six floating binary inputs are available
['0' = 0 V (0...4.5 V); '1' = 24 V (13 ... 33 V)] which can be configured as
required. Should these six inputs be insufficient, you will need to install an
additional electronics module with a further eight binary inputs (optional).
This is where the manner of functioning of the binary inputs is defined.
With the operating mode NAMUR (
shown in Table 5.6 by 'N'.
If operating mode NAMUR is not activated (
behave compatibly with the software edition states of the older version
V4.3.0 (marked with 'X' in Table 5.6).
One of the control functions listed below can be assigned to each input as
required but each function may only be assigned once.
Pin assignments for the individual inputs can be seen in the assignments
diagram 'Electrical connections' on page 3-6.
The unit is shipped with none of the binary inputs preset. Up to four inputs
can be configured in a menu screen. Switching to further menu screens –
and thus to more binary inputs – is always done by pressing the fifth soft
key ("...more").
Attention
It is essential that any changes made to the configuration of the binary
inputs are saved to the user data memory by means of function 75.
Failure to do so runs the risk of an earlier (and unwanted) configuration
being accessed when 'Load user data' (function 75) is executed.
