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 of the cyclic I/O data) cannot be disabled.

Technology Module TM Count 1x24V (6ES7138‑6AA00‑0BA0)
Manual, 10/2013, A5E33002339-AA 13
Capture
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
You can configure whether counting continues from the current counter value or from the
start value after the Capture function.
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 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.

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, 10/2013, A5E33002339-AA 15
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.
In the device configuration of the technology module in STEP 7 (TIA Portal), select "Position
detection for 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
Additional functions
Hardware interrupts
The technology module can trigger a hardware interrupt in the CPU, for example, if a
compare 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 39) are to trigger a hardware interrupt during operation.
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. Select the diagnostic interrupts
(Page 37) in the device configuration freely.
Input filter
To suppress interference, you can configure an input filter for the 24 V encoder inputs and
for the digital inputs.
Distributed application
You can use the technology module in a distributed system by means of an interface module
in the ET 200SP distributed I/O device. The following applications are possible:
●Distributed operation in an S7-1500 system
●Distributed operation in an S7-1200 system
●Distributed operation in an S7-300/400 system
●Distributed operation in a third-party system
Isochronous mode
The technology module supports the system function "Isochronous mode". This system
function enables counter values and measured values to be acquired in a defined system
cycle.
In isochronous mode, the cycle of the user program, the transmission of the input signals
and processing in the technology module are synchronized. The output signals switch
immediately if the relevant comparison condition is met. A change in the state of a digital
input immediately affects the planned reaction of the technology module and changes the
status bit of the digital input in the feedback interface (Page 29).
Data processing
The data that was transmitted to the technology module in the current bus cycle via the
control interface takes effect when it is processed in the internal technology module cycle.
The counter value and the measured value as well as status bits are captured at time Tiand
made available in the feedback interface for retrieval in the current bus cycle.
In isochronous mode, there is always data consistency across all bytes in the feedback
interface.

L+/M supply voltage
Connect the supply voltage (DC 24V) to the L+ and M connections. An internal protective
circuit protects the technology module from polarity reversal of the supply voltage. The
technology module monitors the connection of the supply voltage.
24VDC encoder supply
To supply the encoder and sensors at the digital inputs, the technology module supplies the
DC 24V supply voltage at the 24VDC output with reference to M. Voltage is supplied from
the L+/M supply voltage and monitored for short circuits and overload.
24 V encoder signals/count signals
The 24 V encoder signals are designated A, B and N. You can connect the following encoder
types:
●Incremental encoder with signal N:
The signals A, B and N are connected by means of the correspondingly labeled
terminals. Signals A and B are the two incremental signals phase-shifted by 90°. N is the
zero mark signal which returns one pulse per revolution.
●Incremental encoder without signal N:
The signals A and B are connected by means of the correspondingly labeled terminals.
Signals A and B are the two incremental signals phase-shifted by 90°. The N terminal
remains disconnected.
●Pulse encoders without direction signal:
The counting signal is connected to the A terminal. The count direction is specified via the
control interface. The B and N terminals remain disconnected.
●Pulse encoders with direction signal:
The counting signal is connected to the A terminal. The direction signal is connected to
the B terminal. The N terminal remains disconnected.
●Pulse encoders with counting signal up/down:
The up counting signal is connected to the A terminal. The down counting signal is
connected to the B terminal. The N terminal remains disconnected.
The inputs are not electrically isolated from each other. The inputs are isolated against the
backplane bus.
