Digital control signals

With the digital control signals, function blocks are available which can be used to adjust the application.
Up to three binary signals can be linked using the AND/OR/XOR function (e.g. setpoint changeover, pa-
rameter changeover). Signals can be inverted and delayed. The behavior of the output signal is config-
urable (pulse).
2 control signals can be programmed. Any binary signal can serve as input (digital selector). The device
can output this as follows:
• Inverted
• As a pulse (switch-on time, switch-off time)
• As a delayed switch-on or switch-off operation; (delay time = switch-on time, switch-off time)
• As a pulse signal (pulse time = switch-on time)
• As an AND/OR/XOR function with up to 3 binary signals
Furthermore, it is possible to determine the input signal of the falling edge. For a sampling rate, the out-
put is then set in each case.
NOTE!
The digital control signals are independent of a probe break/short circuit.
The control signals are inactive after power ON.
