8.1 Universal inputs
Digital signals, passive analog signals or active analog signals can be connected to
universal inputs.
The following number of universal inputs is available for the individual types of
devices:
RMU710B: 6 inputs
RMU720B: 8 inputs
RMU730B: 8 inputs
If additional inputs are required, the number of inputs can be increased via
extension modules.
RMZ785: 8 inputs
RMZ787: 4 inputs
RMZ788: 4 inputs
Max. four extension modules from a RMZ785 set, two RMZ787 and two RMZ788
can be connected.
The max. number of inputs thus is:
RMU710B + RMZ785 + RMZ787(1) + RMZ787(2) + RMZ788(1): 26 inputs
RMU720B + RMZ785 + RMZ787(1) + RMZ787(2) + RMZ788(1): 28 inputs
RMU730B + RMZ785 + RMZ787(1) + RMZ787(2) + RMZ788(1): 28 inputs
8.1.1 Activate function
Each input can be assigned an identifier. The identifier also defines the unit of the
input.
If an input is not needed for the application, it can be used for display purposes. To
do this, the identifier/unit is assigned. A special name can then be assigned to the
input. The connected value can be displayed on the operator unit.
