Benefits
Technology modules for counting, measuring and position detection offer you the following
advantages:
●
fast and timely detection of events with fine resolution for high productivity and product
quality
●
hardware-level signal processing for rapid counting, measurement and position detection
for a variety of transducers
●
simple setup and commissioning of the technology functions in the TIA Portal
●
can be used centrally in SIMATIC S7-1500 and in ET 200MP distributed I/O system
●
quick response thanks to different hardware interrupts

Technology module for time-based IO
Extremely high requirements on precision and speed can be met with time-based IO
modules - regardless of the performance of the controller and the fieldbus. Time-based IO
modules ensure that signals are output 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.
