4.8.5 Technology module for time-based IO
Time-based IO modules enable you to achieve maximum precision and speed - regardless of
the performance of the controller and the fieldbus. The time-based IO modules output signals
with a precisely defined response time. The I/O signals are processed on a time basis.
The table below shows the main features of the technology module for time-based IO. In
conjunction with the "Output cam" and "Cam track" technology objects, the TM Timer DIDQ
16x24V ensures highly accurate cam output. In conjunction with the "Measuring input"
technology object, the TM Timer DIDQ 16x24V ensures highly accurate detection of passing
products.

Benefits
The technology modules for time-based IO offers you the following advantages:
• Meets stringent requirements for precision and speed, independent of the CPU and
fieldbus
• Signals are read in and output precisely, to within 1 microsecond
• Exact definition of response times, independent of the application cycle
• Typical use: cam control, length measurement, time measurement, as a probe, for dosing
fluid quantities
