Order Number
6ES7 138-4DA04-0AB0
Compatibility
The 1Count24V/100kHz with the order number 6ES7 138-4DA04-0AB0 replaces the
1Count24V/100kHz with the order number 6ES7 138-4DA03-0AB0 with full compatibility. In
STEP 7 version V5.3 SP2 and later, you can use it in non-isochrone and isochrone modes.
Features
•Connection of a pulse generator to count 24 V signals up to a frequency of 100 kHz.
•Can be operated using terminal modules TM-E15S24-01 and TM-E15S26-A1
•Isochrone mode
•Modified user data interface 1 : Instead of 8 bytes of input data and 8 bytes of output data,
12 bytes of input data and 6 bytes of output data are used, provided the IM 151 supports
this.
•Modes of the 1Count24V/100kHz:
Counting modes:
– Count continuously
– Count once
– Count periodically
Measuring modes:
– Frequency measurement
– Rotational speed measurement
– Period measurement

Position feedback:
– Position detection
•Gate control, synchronization or latch function via digital input (P or M switch)
•One real digital output for direct control or output of the comparison result
•One virtual digital output
•Firmware update1
•Identification data 1
1 The following IM 151 modules support this function: IM 151-1 Standard: 6ES7151-1AA04-
0AB0 and later and IM 151-1 High Feature: 6ES7151-1BA01-0AB0 and later
Connectable Counting Signals
The 1Count24V/100kHz can count the signals of the following encoders:
•24 V pulse encoder with direction level
•24 V pulse encoder without direction level
•24 V incremental encoder with two tracks that are 90o out of phase (rotary encoder).
Adjustment During Operation
•Counting modes
– You can change the function and behavior of the digital outputs during operation
•Measuring modes
– You can change the function of the DO1 digital output during operation
– You can change the integration time and the update time during operation
Configuration
You can use either of the following to configure the 1Count24V/100kHz:
•A GSD file (http://www.ad.siemens.de/csi/gsd)
•STEP 7 V5.3 SP2 and later, or with the HSP (hardware support package available online)
STEP 7 V.5.2 SP1 and later.
Firmware Update
To add functions and for troubleshooting, it is possible to load firmware updates to the
operating system memory of the 1Count24V/100kHz using STEP 7 HW Config.
Notice: When you launch the firmware update, the old firmware is deleted. If the firmware
update is interrupted or canceled for any reason, the 1Count24V/100kHz will no longer
function correctly as a result. Re-launch the firmware update and wait until this has
completed successfully.

2.2 Clocked Mode
Note
The principles of isochrone mode are described in a separate manual.
See Isochrone Mode Function Manual (A5E00223279).
Hardware Requirements
You will require the following for the 1Count24V/100kHz in isochrone mode:
•A CPU that supports isochrone mode
•A master or PROFINET master that supports the equidistant bus cycle
•An IM 151 that supports isochrone mode
Features
Depending on the system parameter assignment, the 1Count24V/100kHz works either in
non-isochrone or isochrone mode.
In isochrone mode, data exchange between the bus master and 1Count24V/100kHz is
isochronous to the cycle.
In isochrone mode, all 8 bytes/12 bytes of the user data interface are consistent.
If an error occurs during parameter assignment, the 1Count24V/100kHz does not go into
isochrone mode.
If isochrone mode fails due to faults or failure/delay of global control (GC), the
1Count24V/100kHz will return to isochrone mode during the next cycle without an error
response.
If isochrone mode fails, the user data interface is not updated.
The Ti/To overlap is supported by the module in firmware version V1.0.1 and later.

You must first adapt the hardware configuration of your existing ET 200S station.
1. Open the relevant project in SIMATIC Manager.
2. Open the HW Config configuration table in your project.
3. Select the 1Count 24V/100kHz Counting Mode from the hardware catalog.
The number 6ES7 138-4DA04-0AB0 C appears in the infotext. Drag the entry to the slot
at which you have installed your 1Count24V/100kHz.
4. Double-click this number to open the "Properties" - 1Count 24V/100kHz (R-S Slot
Number) tab.
5. On the Addresses tab, you will find the addresses of the slot to which you have dragged
the 1Count24V/100kHz. Make a note of these addresses for subsequent programming.
6. On the Parameters tab you will find the default settings for the 1Count24V/100kHz. Leave
the default settings unchanged.
7. Save and compile your configuration, and download the configuration in STOP mode of
the CPU by choosing "PLC > Download to Module".

Testing
Use "Monitor/Modify Variables" to monitor the count value and the gate.
1. Select the "Block" folder in your project. Choose the "Insert > S7 Block > Variable Table"
menu command to insert the VAT 1 variable table, and then confirm with "OK".
2. Open the VAT 1 variable table, and enter the following variables in the "Address" column:
DB1.DBD8 (current count value)
DB1.DBx13.0 (internal gate status)
3. Choose "PLC > Connect To > Configured CPU" to switch to online.
4. Choose "Variable > Monitor" to switch to monitoring.
5. Switch the CPU to RUN mode.
The "internal gate status" bit must be set.
6. Use your counting contact to generate pulses.
Result
You can now see that:
•The UP LED on the 1Count24V/100kHz is on. The status of the UP LED changes with
each new pulse.
•The count value in the block changes.

Wiring Rules
The cables (terminals 1 and 5 and terminals 2 and 8) must be shielded. The shield must be
supported at both ends. To do this use the shield contact (see the
ET 200S Distributed I/O
System
manual).
