Input modes
Digital input (TM15/TM17 High Feature)
If an I/O channel has been configured as a DI, it operates as a standard digital input.
Input of measuring input (TM15/TM17 High Feature)
If an I/O channel has been configured as an input of a measuring input, a time value is
acquired with the input edge. This value represents the time of the event referenced to the
local system time.
Note
The resolution of the measuring time varies according to the type of module:
• In the case of the TM15, the resolution corresponds to the DRIVE CLiQ clock cycle, but is
• In the case of the TM17 High Feature, the resolution is 1 µs.
Enable signals (TM17 High Feature only)
Inputs of measuring inputs can be activated with enable signals (= gate function).
Specifically, channels 10 through 15 – if programmed as enable signals – enable channels 0
through 5, respectively. Each enable signal is level-triggered.
