Note If you have selected the 24V M switch setting for the "Sensor A, B, DI" parameter, you must use M-switching sensors.
Page 30: Gate Functions In Count Modes
1Count24V 2.6 Count Modes 2.6.6 Gate Functions in Count Modes Software Gate and Hardware Gate The 1Count24V has two gates ● A software gate (SW gate), which is controlled by the SW_GATE control bit. The software gate can only be opened by a positive edge of the SW_GATE control bit. It is closed when this bit is reset.
Page 31 T . (See Isochronous Mode (http://support.automation.siemens.com/WW/view/en/15218045) function manual) Gate Control by Means of the SW Gate and HW Gate If the SW gate opens when the HW gate is already open, counting continues starting from the current count status.
Page 32: Latch Function
1Count24V 2.6 Count Modes 2.6.7 Latch Function Introduction There are two latch functions: ● The Latch and Retrigger function ● The Latch function The Latch and Retrigger Function Requirement In order to use this function, you must first select it with the "Latch and Retrigger on Positive Edge"...
Page 33 1Count24V 2.6 Count Modes The latch value is preassigned with its RESET state. It is not changed when the SW gate is opened. Direct loading of the counter does not cause the indicated stored counter status to be changed. If you close the SW gate, counting is only interrupted; this means that when you open the SW gate again, counting is continued.
Page 34 1Count24V 2.6 Count Modes Direct loading of the counter does not cause the indicated stored counter status to be changed. In isochronous mode, the counter status that was latched at the time of the last positive edge before T is displayed in the feedback interface. When you close the SW gate, the effect is either canceling or interrupting, depending on the parameter assignment.
Page 35: Synchronization
1Count24V 2.6 Count Modes 2.6.8 Synchronization Requirement In order to use this function, you must first select it with the "Synchronize on Positive Edge" Function DI parameter. Description Figure 2-11 Once-Only and Periodic Synchronization If you have configured synchronization, the rising edge of a reference signal on the input sets the 1Count24V to the load value.
Page 36 1Count24V 2.6 Count Modes 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. ● Synchronize once only: If the enable bit is set, the first edge loads the 1Count24V with the load value.
Page 37: Behavior Types Of The Outputs In Count Modes
1Count24V 2.6 Count Modes 2.6.9 Behavior Types of the Outputs in Count Modes Introduction The 1Count24V allows you to store two comparison values, which are assigned to the digital outputs. The outputs can be activated, depending on the counter status and the comparison values.
Page 38 1Count24V 2.6 Count Modes Counter status ≤ Comparison Value and Counter Status ≥ Comparison Value If the comparison conditions are fulfilled, the respective comparator switches on the output. The status of the output is indicated by STS_DO1 and STS_DO2. The control bits CTRL_DO1 or CTRL_DO2 must be set for this. The comparison result is indicated by the status bits STS_CMP1 or STS_CMP2.
Page 39 1Count24V 2.6 Count Modes Switch at Comparison Values The comparator switches the output when the following conditions are met: ● The two comparison values must be loaded using the load functions CMP_VAL1 and CMP_VAL2, and ● After the comparison values are loaded, the DO1 output must be enabled with CRTL_DO1.
Page 40 1Count24V 2.6 Count Modes Isochronous mode: In isochronous mode, as well, the DO1 output is switched as soon as the comparison condition is fulfilled and is therefore independent of the bus cycle. The status of the virtual output DO2 is signaled at time T Figure 2-12 V2 <...

Page 55: Sequence Of Continuous-Action Measurement
1Count24V 2.7 Measurement Modes 2.7.2 Sequence of continuous-action measurement Measuring Principle The 1Count24V counts each positive edge of a pulse and assigns it a time value in µs. The update time indicates the time interval at which the measured value is updated by the module in the feedback interface.
Page 56 1Count24V 2.7 Measurement Modes If the "1 Pulse per dynamic measuring time" estimated measured value is less than the last measured value during the frequency and speed measurement, this estimated measured value is output as the new measured value. With the period measurement, the dynamic measuring time is output as the estimated period if the dynamic measuring time is greater than the last measured period.
Page 57 1Count24V 2.7 Measurement Modes The following figure illustrates the principle of continuous measurement using frequency measurement as an example. Figure 2-22 Principle of Continuous Measurement (Frequency Measurement Example) Gate Control To control the 1Count24V, you have to use the gate functions. Isochronous Mode In isochronous mode, the 1Count24V accepts control bits and control values from the control interface in each bus cycle and reports back the response in the same cycle.
Page 58 1Count24V 2.7 Measurement Modes Integration Time and Update Time in Isochronous Mode If the integration time/update time lasts several T cycles, you can recognize the new measured value in the user program at the bit STS_CMP1 status bit (measurement completed) of the feedback interface. This enables monitoring of the measuring operation or a synchronization with the measuring operation.

1Count24V 2.9 Position feedback 2.9.2 Position Detection Definition In this mode, the 1Count24V counts continuously starting from the load value: ● If the 1Count24V reaches the high count limit when counting up, and another count pulse then comes, it will jump to the low count limit and continue counting from there without losing a pulse.
Page 93: Gate Functions For Position Detection
1Count24V 2.9 Position feedback 2.9.3 Gate Functions for Position Detection Software Gate and Hardware Gate The 1Count24V has two gates ● A software gate (SW gate), which is controlled by the SW_GATE control bit. The software gate can only be opened by a positive edge of the SW_GATE control bit. It is closed when this bit is reset.

1Count5V 3.7 Measurement Modes 3.7.2 Sequence of continuous-action measurement Measuring Principle The 1Count5V counts each positive edge of a pulse and assigns it a time value in µs. The update time indicates the time interval at which the measured value is updated by the module in the feedback interface.
Page 167 1Count5V 3.7 Measurement Modes If the "1 Pulse per dynamic measuring time" estimated measured value is less than the last measured value during the frequency and speed measurement, this estimated measured value is output as the new measured value. With the period measurement, the dynamic measuring time is output as the estimated period if the dynamic measuring time is greater than the last measured period.
