Analog inputs

Signal processing using the analog inputs is shown in the function diagrams listed below.
Properties
● Hardware input filter set permanently
● Simulation mode parameterizable
● Adjustable offset
● Signal can be inverted via binector input
● Adjustable absolute-value generation
● Noise suppression (p4068)
● Enabling of inputs via binector input
● Output signal available via connector output
● Scaling
● Smoothing
Note
Parameters p4057 to p4060 of the scaling do not limit the voltage values / current values (for
TM31, the input can be used as current input).
Analog input of Control Unit 310-2
Control Unit CU310-2 has an integrated analog input at terminal strip X131, terminals 7 and
8, an analog input. The input is preset as current or voltage input using DIP switch S5. The
input can be further differentiated using p0756 [x]:
The characteristic of the analog input can be scaled using parameters p0757 to P0760.
The value of the analog input can be read out from r0755.
