14 Manual, 02/2017, A5E33002339-AB
2.2
Functions
2.2.1
Detection of counting signals
Counting refers to the detection and summation of events. The counters of the technology
module detect encoder signals and pulses and evaluate them accordingly. The count
direction can be specified using encoder or pulse signals or through the user program.
You can control the counting processes with the digital inputs.
You can specify the counter characteristics using the functions described below.
Counting limits
The counting limits define the counter value range used. The counting limits are configurable
and can be modified during runtime with the user program.
The maximum possible counting limit is 2147483647 (231–1). The minimum possible
counting limit is –2147483648 (–231).
You can configure the response of the counter at the counting limits:
●Continue or stop counting upon violation of a counting limit (automatic gate stop)
●Set counter value to start value or to other counting limit upon violation of a counting limit
Start value
You can configure a start value within the counting limits. The start value can be modified
during runtime with the user program.
Depending on the parameter assignment, the technology module can set the current counter
value to the start value upon synchronization, upon Capture function activation, upon
violation of a counting limit or when the gate is opened.
Gate control
Opening and closing the hardware gate and software gate defines the period of time during
which the counting signals are captured.
The control of the hardware gate takes place externally via the digital inputs of the
technology module. Control of the software gate takes place via the user program. The
hardware gate can be enabled through parameter assignment. The software gate (bit in the
control interface (Page 53) of the cyclic I/O data) cannot be deactivated.

2.2 Functions
Technology Module TM Count 1x24V (6ES7138-6AA00-0BA0)
Manual, 02/2017, A5E33002339-AB 15
Capture (Latch)
You can configure an external reference signal edge that triggers the saving of the current
counter value as Capture value. The following external signals can trigger the Capture
function:
●Rising or falling edge of a digital input
●Both edges of a digital input
●Rising edge of the N signal at the encoder input
When using a digital input, you can specify whether counting is to continue from the current
counter value or from the start value after the Capture function. When the rising edge of the
N signal at the encoder input is used, counting is to continue from the current counter value
after the Capture function.
Hardware interrupts
The technology module can trigger a hardware interrupt in the CPU, for example, if a
comparison event occurs, in the event of overflow or underflow, in the event of a zero
crossing of the counter and/or of a change of count direction (direction reversal). You can
specify which events (Page 64) are to trigger a hardware interrupt during operation.

2.2.2
Measured value determination
The following measuring functions are available:
Measurement type
Description
Frequency measurement The mean frequency is calculated at set measuring intervals on the
basis of the time profile of the count pulses and returned in hertz as
the floating point number.
Period measurement The mean period duration is calculated at set measuring intervals
on the basis of the time profile of the count pulses and returned in
seconds as the floating point number.
Velocity measurement The mean velocity is calculated at set measuring intervals on the
basis of the time profile of the count pulses and other parameters,
and returned in the configured unit of measurement.
The measured value and the counter value are available concurrently in the feedback
interface.
Update time
You can configure the interval at which the technology module updates the measured values
cyclically as the update time. Setting longer update time intervals allows uneven measured
variables to be smoothed and increases measuring accuracy.
Gate control
Opening and closing the hardware gate and software gate defines the period of time during
which the counting signals are captured. The update time is asynchronous to the opening of
the gate, which means that the update time is not started when the gate is opened. After
closing, the last measured value captured continues to be returned.
Measuring ranges
The measuring functions have the following measuring range limits:
Measurement type
Low measuring range limit
High measuring range limit
Frequency measurement
0.04 Hz
800 kHz*
Period measurement
1.25 µs*
25 s
Velocity measurement Depends on the configured number of "increments per unit" and the
"time base for velocity measurement"
* Applies to 24 V incremental encoders and "quadruple" signal evaluation.
All measured values are returned as signed values. The sign indicates whether the counter
value increased or decreased during the relevant time period.

Manual, 02/2017, A5E33002339-AB 17
2.2.3
Switching the outputs at comparison values
You define two comparison values that can control the two digital outputs independent of the
user program. The comparison values are configurable and can be modified during runtime
with the user program.
Comparison values in the Counting mode
You define two comparison values in the Counting mode. If the current counter value meets
the configured comparison condition, the corresponding digital output can be set to directly
initiate control processes in the process.
Comparison values in the Measuring mode
You define two comparison values in the Measuring mode. If the current measured value
meets the configured comparison condition, the corresponding digital output can be set to
directly initiate control processes in the process.
2.2.4
Position input for Motion Control
You can use the technology module with an incremental encoder for position detection with
S7-1500 Motion Control . Position detection is based on the counting function of the
technology module which evaluates the captured encoder signals and sends them to the
S7-1500 Motion Control.
The range of functions of the technology module has the following limitations in this case:
●Counter behavior not configurable
●No functions for digital inputs available
●No comparison functions for digital outputs available
●No hysteresis available
●No hardware interrupts available
In the device configuration of the technology module in STEP 7 (TIA Portal), select "Position
input for technology object "Motion Control"".
Additional information
A detailed description of the use of Motion Control and its configuration is available in the
function manual S7-1500 Motion Control as a download from the Internet
(http://support.automation.siemens.com/WW/view/en/59381279).

2.2.5
Fast Mode
You can use the technology module in Fast Mode for very fast detection of the counter value
in case of compressed functionality. In Fast Mode, you have access to a reduced feedback
interface but not to a control interface. This means you can use a shorter send clock for the
CPU.
The range of functions of the technology module has the following additional limitations 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
To do this, select "Fast Mode" operating mode in the device configuration of the technology
module in STEP 7 (TIA Portal).
You can specify the behavior of the counter using the functions described below.
Counting limits
The counting limits define the counter value range used. The counter limits are configurable
and can be modified during runtime using data record 128 but not through the control
interface.
The maximum possible counting limit is 33554431 (225–1). The minimum possible counting
limit is 0.
You can configure the response of the counter at the counting limits:
●Continue or stop counting upon violation of a counting limit (automatic gate stop with
configured hardware gate)
●Set counter value to start value or to other counting limit upon violation of a counting limit
Start value
You can configure a start value within the counting limits. The start value can only be
modified during runtime with data record 128.
Depending on the parameter assignment, the technology module can set the current counter
value to the start value upon synchronization, upon violation of a counting limit or when the
configured hardware gate is opened.

Gate control
Opening and closing the hardware gate (HW gate) defines the period of time during which
the counting signals are recorded.
The control of the hardware gate takes place externally via the digital inputs of the
technology module. The hardware gate can be enabled through parameter assignment. All
count signal are recorded when you do not configure a hardware gate. A software gate is not
available.

2.2.6
Additional functions
Synchronization
You can configure the edge of an external reference signal to load the counter with the
specified start value. The following external signals can trigger a synchronization:
●Rising or falling edge of a digital input
●Rising edge of the N signal at the encoder input
●Rising edge of the N signal at the encoder input depending on the level of the assigned
digital input
Hysteresis
You can specify a hysteresis for the comparison values within which a digital output will be
prevented from switching again. An encoder can come to a standstill at a specific position,
and slight movements may make the counter value fluctuate around this position. If a
comparison value or a counting limit lies within this fluctuation range, the corresponding
digital output will be switched on and off with corresponding frequency if hysteresis is not
used. The hysteresis prevents these unwanted switching operations.
Diagnostic interrupt
The technology module can trigger a diagnostic interrupt in the event of a missing supply
voltage or an error at the digital outputs, for example. You enable the diagnostic interrupts
(Page 60) in the device configuration.
Input filter
To suppress interference, you can configure an input filter for the 24 V encoder inputs and
for the digital inputs.
