TM15 / TM17 High Feature Operating Manual

6.1.3 Output modes
Digital output (TM15/TM17 High Feature)
If a channel has been configured as a DO, it operates as a standard digital output. See figure
under "System behavior for digital inputs and outputs"
Output of output cam (TM15/TM17 High Feature)
This operating mode treats output channels as outputs of an output cam (see section on
"System Behavior"). The outputs are enabled and disabled depending on the time values
calculated in the SIMOTION technology object.
Switching times are specified by two time values (ON and OFF values) referenced to the
local system time.
NOTICE
The resolution of the switching times varies according to the type of module:
• In the case of the TM15, the resolution corresponds to the DRIVE CLiQ clock cycle, but
is at least 125 µs.
• In the case of the TM17 High Feature, the resolution is 1 µs.

Output of output cam with enable signal (TM17 High Feature only)
The "Output of output cam with enable" mode treats output channels as outputs of an output
cam, for which an enable signal is required (available on channels 0 through 5 only). This
mode is selected on a channel-by-channel basis during I/O configuration.
Provided that an enable signal exists, output cams are output as a function of the time
values calculated in the SIMOTION technology object.
Switching times are specified by two time values (ON and OFF values) referenced to the
local system time.
Note
Provided that the enable function for outputs of output cams is used and the output cams are
to be output "inverted", an inverted output must be assigned for TM17 High Feature (an
inversion of the output on the Output Cam or Output Cam Track technology object causes a
low level to be output whenever there is no enable, which would correspond in this case to
an activated output cam).
