7.2.4 Numerical Entry
The function Numerical input supplies a numerical value which can
be adjusted in the Parameters menu of the CM device. As an
alternative, it can also be set through a connected PC.
The Inscription parameter is used as a menu option in the input
menu for this purpose. The permissible input range runs from
-2,000,000.000 to +2,000,000.000.
Modifications made in the CM device during the running time also
remain in effect after switch-off. The value that is set under Start
value
will used after the first-time transfer of the CM program to the
CM device until the first change is made.
Inputs: -
Outputs: y: (Numerical)
Parameters: p

: Starting value (Numerical)

2
: Inscription (character string)
7.2.5 Boolean Entry
The Boolean input function supplies a Boolean value, which can be
set in the Parameters menu of the CM device.
As an alternative, it can also be set through a connected PC.
The Inscription parameter is used as a menu option in the input
menu for this purpose. The input is accomplished on the CM device
by selecting "Yes" or "No".
Modifications made in the CM device during the running time also
remain in effect after switch-off. The value that is set under Start
value
will used after the first-time downloading of the CM program
into the CM device until the first change is made.
The Functionality paramter defines how the input is interpreted. The
following settings are possible:
Switch
A menu option is generated on the CM device with which the input
value can be switched on or off. . This functionality is used to active
certain paths in the evaluation logic.
Key
When the value on the CM device is switched on, then only one
impulse is generated in the evaluation logic and the option switches
itself off in the menu again immediately. A key function is simulated,
so to speak. This functionality can be used to trigger events in the
evaluation logic.
