Behavior Types Of The Outputs In Count Modes - Siemens SIMATIC ET 200S Operating Instructions Manual

The following conditions apply:
• The counting mode must have been started with the SW gate.
• The "Enable synchronization CTRL_SYN" control bit must be set.
• In once-only synchronization, the first edge loads the 1Count24V/100kHz with the load
• In periodic synchronization, the first edge and each subsequent edge load the
• After successful synchronization, the STS_SYN feedback bit is set. It must be reset by
• The signal of a bounce-free switch or the zero mark of a rotary encoder can serve as the
• The STS_DI feedback bit indicates the level of the reference signal.
In isochrone mode, the set feedback bit STS_SYN indicates that the rising edge on the
digital input was between time T

Behavior Types of the Outputs in Count Modes

Introduction
The 1Count24V/100kHz lets you store two comparison values, which are assigned to the
digital outputs. The outputs can be activated, depending on the count and the comparison
values. The various ways of setting the behavior of the outputs are described in this section.
Description
The 1Count24V/100kHz has a real digital output and a virtual digital output that exists only
as a status bit in the feedback interface.
Parameters can be assigned for both outputs ("Function DO1" and "Function DO2"
parameters).
You can change the function and the behavior of the digital outputs during operation. The
new function takes effect immediately.
You can choose from the following functions:
• Output
• Count ≥ comparison value
• Count ≤ comparison value
• Pulse on reaching the comparison value
• Switch at comparison values (DO1 only)
