Set switch or button mode
Feature bit
Number of the
Feature
bit: 4
Setting switch or button mode (input signal as pulse signal or as static signal)
You can use this
Feature
bit to select the mode switchover between manual and automatic
mode and to determine whether the setpoint is selected with a switch or with two 1-active
control inputs (buttons). This
Feature
bit has no influence on the control commands sent to
the module such as e.g. ‘Stop counter’ or ‘Start dosing’.
The
Feature
bit affects the following control inputs:
● Mode switchover (parameters
AutModLi
and
ManModLi
or
AutMod2Li
and
ManMod2Li
)
● Internal and external setpoint input of the dosing unit (parameters
DSP_ExtLi
and
DSP_IntLi
)
The
Feature
bit acts on control inputs in the form of a pulse (button mode) or a static signal
(switch mode).
You can find the commands for controlling the block in the relevant section on block operating
modes. They are always the parameters that are used for the automatic operation of a block.
Bit = 0: Button mode: Each automatic command is assigned to a control input. This has a
latching reaction and is 1-active.
Mode:
●
AutModLi/AutMod2Li = 1
for setting "Automatic" operating mode
●
ManMod1Li/ManMod2Li = 1
for setting "Manual" operating mode
Setpoint selection:
●
DSP_ExtLi = 1
to select the external setpoint and
●
DSP_IntLi = 1
to select the internal setpoint
Bit = 1: Switching mode: two static automatic commands are assigned to a control input.
Mode:
●
AutModLi/AutMod2Li = 1
for setting "Automatic" operating mode
●
ManMod1Li/ManMod2Li = 0
for setting "Manual" operating mode
Setpoint selection:
●
DSP_ExtLi = 1
to select the external setpoint
●
DSP_IntLi = 0
to select the internal setpoint
The
ManMod1Li/ManMod2Li
and
DSP_IntLi
inputs have no effects.
