Absolute level-controlled (TM17 High Feature)

Required configuration for level-controlled HW enable
● Cam track TO or output cam TO is configured
● Digital output on TM17 High Feature parameterized for cam track output, and level-
● Digital output configured for cam track output (HW address)
● Cam track TO or output cam TO must be active.
Level-controlled enable procedure
For cam tracks with a level-controlled enable, output cams are output for as long as the cam
track is active in the TO (set with the _enableCamTrack command) and as long as a hardware
enable signal, which has been parameterized on the TM17 High Feature, is present. This
means that a cam track can also be output multiple times with a continuous enable signal. An
output cam, which is already active, is still output even if the enable is deactivated.
An output cam cannot be controlled until a hardware enable signal is present at the TM17 High
Feature. If the enable takes place within an output cam, it is no longer output. Subsequent
output cams are however output. This can be assigned parameters in the track enable of the
TO (see Chapter Start mode and stop mode).
It is also possible to operate the output with inverted logic, i.e. the enable input on the TM17
High Feature can be operated inversely and then works in LOW-active mode.

Note
With level-controlled HW enables, the state system variable does not indicate the status of
the output (DO), but rather the status of the cam track signal (C-TS).
