the building automation system.
Address key Accessory part that has to be inserted in the TX-I/O module.
The mechanical coding of the key assigns the module its address.
Bus connection module "Passive" module that relays the bus signal and the module supply from one I/O row to the next
and/or feeds an additional field supply for peripheral devices (AC/DC 12...24 V)
Bus Interface Module (BIM) Interface between a controller and the bus of the TX-I/O modules.
Bus master Device with general functions for a group of I/O modules.
TX-I/O module bus (island bus) Communication bus between the bus master (bus interface module, BIM) and the connected TX-
I/O modules.
Also serves as carrier of the module supply and field supply.
The bus is constructed by plugging the TX-I/O modules together.
Electronic unit Removable part of the TX-I/O module with the module electronics.
Functional test Control of an output (separate island bus) – i.e., program commands are not effective.
When disconnecting the connection of the BIM tool (or in the case of power failure), the outputs
assume their original values again.
I/O function Function in an I/O point that defines the point's operation mode (e.g., signal input, voltage output
0...10 V).
Specific functions can occupy a number of I/O points (e.g., multistage switching output).
I/O island All TX-I/O devices (bus users) that are physically connected to the same island bus segment and
connected by a common bus master.
I/O module Device in which the physical signals of the field devices are converted to software process values
and vice versa.
An I/O module has a number of I/O points specified by the module type. The modules are divided
into a terminal socket and a pluggable electronic unit.
I/O point Smallest addressable unit in an I/O module.
One or more I/O points (e.g., a three-stage switching output) correspond to one data point/channel
on the automation station.
I/O row An I/O island comprising different rows of modules.
Each row starts either with a bus master, a supply module or a bus connection module.
Terminal Connection unit for the cables of the peripheral devices (field devices).
Terminal socket Part of the TX-I/O module that is mounted on the standardized mounting rail and on which the wiring
is implemented.
The terminals implement the function of switching cabinet series terminals.
Configuring Specification of the functionality of an I/O point by defining an I/O function and its parameters.
An I/O function that already exists in a module before the downloading and its I/O points are first
disabled (for details, refer to the TX-I/O engineering documentation [3]).
Local override control Operation of an output using keys on the module.
Deletion key Used to reset the module function to the factory settings.
Inserted in place of the address key for later removal.
Process value Software image of the physical value in the peripheral device.
Communicated on the bus.
Parameterize Change the properties of an I/O function during the configuration or operation (for details, please
refer to the TX-I/O engineering documentation [3]).
Supply module "Active" power supply that converts AC 24 V to DC 24 V.
Provides module power supply for operation of the module electronics and supply for field devices
with DC 24 V and AC 24 V.
Tool override control Control of an output using a tool.

2 General
2.1 Overview
Profinet BIM is an interface module which enables to access from the Simatic
infrastructure to
process data
configuration data and
parameters
of TX-I/O modules.
2.2 Application
The purpose of Profinet BIM is to connect the two communication media, TX-I/O
and PROFINET-DP, and in this way to allow access to the DESIGO I/O modules
from a SIMATIC S7.
Within SIMATIC
Profinet BIM is handled as a Profinet I/O device and
TX-I/O modules are represented as Profinet I/O modules.
In the Profinet infrastructure, Profinet BIM behaves as a PNIO device and
supports the datagram data exchange in the direction of the Profinet IO
controller (SIMATIC S7).
On the island bus (communication bus of the TX-I/O modules) the Profinet BIM
operates as the island bus master. Consequently, it is responsible for the data
flow to and from the TX-I/O modules.
All data forwarded via the Profinet BIM is converted to the datagram format used
by SIMATIC S7.
Engineering of the Profinet BIM is carried out using standard Profinet I/O
engineering methods. The properties of the TX-I/O modules are saved in the
product-specific GSDML file. The GSDML file provides the basis for engineering
with the Profinet project engineering tool (e.g., Simatic Manager).
The Profinet BIM does not require engineering. It receives its parameters from the
Profinet I/O controller assigned to it (e.g., from the SIMATIC S7).

2.3 Configuration
The following figure shows how the TX-I/O modules are connected to SIMATIC S7
(S7-200, 300 and 400) and to the higher-level management PC.
2.4 Features
On the Profinet side, Profinet BIM supports 100-MHz full duplex Ethernet
communication.
The performance (number of TX-I/O modules per Profinet BIM that can be used)
depends on the following specific conditions:
64 TX-I/O modules (max.)
Programmable TX-I/O module addressing range 1–120
It is recommended to start from 1 and increase in steps.
Maximum of 256 input bytes made up of the following data:
– Total of all process data bytes of all input modules
– Number of input modules
– Number of output modules.
Maximum of 256 output bytes made up of the following data:
– Total of (all) process data bytes of all output modules
The cyclical input and output data of a configured Profinet BIM can be calculated
using the following table. The number of input and output data bytes are added
together for each connected TXM module and each channel function.

2.5 Cycle Times of Profinet BIM
The cyclic process data exchange between Profinet and the island bus runs with
different cycle times.
Possible cyclic process data exchange intervals are: 8, 16, 32, 64, 128, 256 ms.
The required interval is set by the user during the SIMATIC S7 hardware
configuration.

3 Engineering
Engineering is based on the GSDML file. It is standardized in accordance with the
GSDML Specification for Profinet IO V2.2.
The engineering tool (Simatic Manager) is part of the engineering process. It needs
to be informed by an import about which GSDML file to use for the Profinet BIM.
As a result of the import, the Profinet BIM will then appear as a field device in the
hardware catalog of the program (path: ...\Profinet IO\I/O\TX-I/O).
Engineering can be carried out in the following two different ways:
1 a) First, the application is created and loaded into the CPU and
b) then the periphery is configured, or
2 a) First, the modules are configured and tested, and
b) then the application is loaded.
In this case, specific organization blocks (OBs) must be available. If one of
these organization blocks is missing, then in the event of
configuration errors and
if a module fails during running operation
the CPU will be stopped.
The following organization modules should be available:
OB no OB name Meaning
OB82 I/O Point Fault 1 Diagnostics alarm
OB83 I/O Point Fault 2 Removal/insertion (of modules)
OB85 OB Not Loaded Fault Program operation error
OB86 Loss of Rack Fault Module rack failure
OB122 Module Access Error Program operation error
can be found in the online help function of the SIMATIC Manager
If no organization blocks are yet available, you can find information as follows:
SIMATIC Manager > Help > Find tab > Organization blocks
or
SIMATIC Manager > Wizard for new project > Next > Select CPU type >
Next > mark the required OB > Help for OB button
Note
In this sequence do not click the Finish button.
We assume in this manual that are beginning a project from the very start. The
following procedure is useful:
1. SIMATIC Manager Create a Step7 project
See Section 3.1 – Create a Step7 project
2. Import Profinet BIM GSDML file

3.2 Install GSDML File
After installing a SIMATIC Manager
the GSDML file (data, xml file) and
the corresponding image file (icon, bmp file)
are not available. They must be imported.
Before the installation, you must copy the files to a folder outside
C:\...\Siemens\Step7\GSD\... – otherwise they will not be installed. During the
installation, the files are written to the above-mentioned folder.
1. Locate the GSDML file and bmp files
(this is only an example): \\Ch021090.ww020.siemens.net\TX-
IO_for_Simatic\04_Firmware\Test_Release\Firmware TXB1.PROFINET\...
This is not the full path name. You would usually want to download the
latest version. This version can be found under the specified path as shown in
the adjacent figure – e.g., V0.2.17.
2. Copy files to the following path in the local PC:
C:\Program Files\Siemens\Step7\S7tmp
This path must be used. The files are not permitted to be copied to the
actual target folder. This is done automatically by the installation program
during the installation.
1. Open the hardware configuration window.
2. Tools >Install GSD Files
Opens Install GSD Files
3. Select the required GSDML file
The possible files are listed in the text field.
4. Install button.
5. Close button.
The file is imported into the engineering tool. After this procedure the Profinet
BIM appears in the hardware catalog (...\Profinet IO\I/O\TX-I/O).

6. Import Profinet BIM to the Profinet network by drag&drop of the
TXB1.Profinet BIM.
After releasing the mouse button, the Profinet BIM is inserted and is displayed
in the Profinet network.
Note
When clicking the Profinet BIM, the slot allocation and I/O addresses are
displayed in detail in the station window.
7. Rightclick I/O bar > context menu: Object Properties
Opens the PROFINET I/O system properties dialog field.
8. Update time tab: mark the device > Edit button
Opens the Edit update time/mode dialog field.
9. Set the update time to 256 ms using the dropdown list box.
This is a recommendation. A higher clock rate makes no sense since the
island bus is clocked at 512 ms.
10. Close with OK.
3.3 Engineering the Profinet BIM with the
SIMATIC Manager
The Profinet BIM is a modular device. It supports specific TX-I/O modules and their
corresponding channel functions.
TXM1.8D TXM1.8U TXM1.8X TXM1.6R TXM1.6RL
TXM1.16D TXM1.8U-ML TXM1.8X-ML TXM1.6R-M TXM1.8P
The following sections explain the engineering procedure in terms of
module configuration
submodule configuration and
parameterization.
Profinet BIM supports 120 slots. TX-I/O modules can be inserted in any slot
within this range (1...120).

Siemens TX-I/O PROFINET BIM V1.0 CM110564en_02
Building Technologies Engineering 23.09.2010
Up to 64 TX-I/O modules can be connected with a Profinet BIM at the same
time.
3.3.1 Module Configuration
The TX-I/O modules supported by the Profinet BIM are found in the hardware
catalog under the TXB1.Profinet submodule.
Please observe the following points when working on the module configuration:
Recommendation: Keep the addresses identical with the parameterized
SIMATIC input and output addresses.
---> TX-I/O module addresses must agree with the number of the slot in which
they are located and
---> TX-I/O modules must be inserted in the slot whose number matches
the corresponding TX-I/O module address.
Slots suitable for accepting TX-I/O modules are marked in green.
A TX-I/O module can be deleted at any time with the Del button. In doing so, you
must reply to a security prompt (example for a TXM1.6R module):
1. Upper window section: click the required submodule
Opens the TX-I/O module in the lower window section.
2. Hardware catalog: insert the required TX-I/O module by drag&drop.
When dragging the object, the free slots are displayed in green. After
dropping the module, a window similar to the one shown below appears
(extract, with TXM1.6R as an example).
3. Save
We recommend saving at meaningful intervals, but always for each
inserted TX-I/O module.

Building Technologies Engineering 23.09.2010
3.3.2 Channel Configuration
The functionality of the channels of the TX-I/O modules is
mapped to the input/output submodules. The supported
submodules (2) are listed in the hardware catalog under
each TX-I/O module (1).
Submodules can be inserted in any free subslot (free subslots are marked in
green).
Subslot 1 of the modules is defined at the factory with an object that is typical for
the corresponding module. The subslot contains
the binary I/O process data of the configured binary I/O channels and
the override information of configured output channels.
Module channels begin with subslot number 2 for the first I/O channel and end with
the subslot number of the maximum number of module channels + 1.
Multistate output channels (MO) must be carefully connected.
The channels must be integrated in precisely the order in which they appear in
the catalog.
1. Hardware catalog: open the module with the affected objects
2. Enter the required objects in the TX-I/O module in the rack in the correct
order by drag&drop.
This only works with individual objects – multiselection is not possible.
3. Save
3.3.3 Parameterizing Submodules
The functions with subslots of connected TX-I/O modules can be parameterized in
the corresponding properties dialog box. The dialog box is opened by
doubleclicking on the submodule.
Parameterized values are transferred to the controller during loading of the project.
The controller sends the parameter values to the Profinet BIM only during the
Profinet communication start. After communication has started, the channel
