control command is sent from the SFC, the command is reset automatically after a step is
exited.

Number of the Feature bit: 3
With this Feature bit, you select how the block handles commands for the control settings
(for example motor on) via the interconnected input parameters.

The control commands are reset by the block. This, for example, ensures that if a
control command is sent from the SFC, the command is reset automatically after a step is
exited.
Setting switch or button mode
Number of the Feature bit: 4
Determine whether a separate interconnectable 1-active control input has to be used for
every automatic command of the block or two automatic commands are assigned to a
control input (input signal as pulse signal or as static signal).
The Feature bit affects the following control inputs:
● starting and stopping a motor
● opening and closing a valve
● switching modes (parameters
AutModLi and ManModLi)
Setpoint specification internal and external is given in the form of a pulse (pushbutton
operation) or a static signal (switching mode).
You can find the commands for controlling the block in the relevant section on block
operating modes. These are the parameters that are always used for the automatic
operation of a block.
Button mode: Each automatic command is assigned to a control input. This has a
latching reaction and is 1-active.
