4.4 Fast Mode
You can use the technology module in Fast Mode for very fast acquisition of the counter
value with compressed functionality. A reduced feedback interface but no control interface is
available in Fast Mode. This allows you to use a shorter send clock for the CPU.
The scope of functions of the technology module has the following additional restrictions in
Fast Mode:
● Parameter change in RUN only possible with data record 128
● Count/position value range: 25 bits
● No measured value available
● No software gate available
● No Capture function available
● No hardware interrupts available
● Combined error message (feedback bit) that is acknowledged automatically
4.4.1 Configuring
Introduction
You configure the technology module and assign its parameters with the configuration
software.
The functions of the technology module are controlled and checked by the user program via
the feedback interface.
