Configuration Instructions for the LB/FB Remote I/O System
Introduction
1 Introduction
These instructions will help you commission and configure an LB/FB remote I/O system using
the SIMATIC Manager STEP 7.
1.1 Purpose of the Instructions
These instructions describe the key functions in STEP 7 that help you commission an LB/FB
remote I/O system. Customer-specific adaptations are not described. Note that software
changes cannot always be taken into account, meaning that deviations in the description may
occur.
Note
For more information about STEP 7, refer to the corresponding online Help or documentation.
Commissioning involves the integration of the LB/FB remote I/O system in a PROFINET network. STEP 7 is used for configuration, then parameterization of the LB/FB remote I/O system
takes place.
The hardware configuration is an offline process that is completed without a connection to the
control panel (PLC). In STEP 7, a project is created and the LB/FB remote I/O system is configured. The selection of the gateway and the I/O modules from the hardware catalog enables the
exact structure of the LB/FB remote I/O system to be replicated in the software project. In the
configuration table, each I/O module is automatically assigned an address. When the automation system starts up, the target configuration created with STEP 7 is compared with the actual
configuration. Any errors can thus be detected and reported immediately.
After configuration, the LB/FB remote I/O system is parameterized. Parameterization involves
setting the device characteristics such as the addresses and stipulating the communication
characteristics. The I/Q addresses are used, for example, to define where each binary or analog signal can be read in or out.
When device configuration is complete, the configuration data is compiled in a format that the
control panel can understand and loaded into the control panel. You can use variable tables to
save different test environments. You can then reproduce tests and process monitoring multiple
times during commissioning or for service purposes.
1.2 Technical Basics

Commissioning the LB/FB Remote I/O System
3 Commissioning the LB/FB Remote I/O System
Commissioning involves the integration of an LB/FB remote I/O system into a PROFINET network and its configuration. Commissioning also involves compiling the project configuration
and transferring it to the control panel.
The following hardware components of the LB/FB remote I/O system are relevant to commissioning with STEP 7:
• Gateway
• I/O modules
The hardware components must be replicated in the project to configure the LB/FB remote I/O
system.
The gateway is the component that communicates with the control panel. The properties must
be defined to be able to configure the gateway. These properties include the device name and
the IP address.
During parameterization of the channels, the measurement behavior of the I/O modules that
process input signals is defined. At the same time, the behavior of the I/O modules that emit
output signals is defined. In STEP 7, the channels are the submodules. They are available in
the hardware catalog under the I/O modules.
To commission the LB/FB remote I/O system, perform the following steps:
• Preparation for commissioning
• Create the project
• Set up the control system
• Install the GSDML file
• Configure/parameterize the LB/FB remote I/O system
• Compile a project configuration
• Transfer a project configuration
• Check the connection
A description of how to perform the individual steps is provided on the following pages.
Note
The illustrations and information contained in this description relate to the following variants:
• Siemens SIMATIC S7 control panel (PLC/CPU)
• Siemens STEP 7 configuration software
• GSDML file for the LB/FB remote I/O system
Information about other variants can be found in the technical documentation of the control
panel and the associated software.

Commissioning the LB/FB Remote I/O System
3.1 Preparation for Commissioning
It is necessary to plan the commissioning of an LB/FB remote I/O system beforehand. Planning
ensures that all files and information are available to enable efficient commissioning.
You will need the following files and information for commissioning:
GSDML file
A device description file (GSDML file) is required to use the LB/FB remote I/O system. The current GSDML file can be downloaded from our website: www.pepperl-fuchs.com. Enter the
product name or item number in the Product/Keyword search box and click on Search.
Select your product from the list of search results and click on the Software tab in the product
information list. A list of all available downloads is displayed.
The installation of the GSDML file is explained in chapter 3.4.
IP Address
When assigning the IP address, observe fundamental addressing rules, e.g., regarding the use
of private or public address areas. Check that the IP address can be used in your automation
network (no duplicate address assignment, etc.).
When assigning an address for the gateway or the LB/FB remote I/O system, the following IP
address variants are available:
• Dynamic IP address assigned via DHCP (DHCP default setting set to "on")
• Static, customer-specific, or customer-configurable IP address
IP address assignment is described in chapter 3.5.2.
Gateway name
Each PROFINET device is identified via its "Device Name." The gateway must have a unique
name before it can be addressed by the control panel.
The following rules must be observed when using the PROFINET specification for the PROFINET device name.
• The device name must not exceed 240 characters. Permitted characters:
• Letter "a" to "z,"
• Digits "0" to "9,"
• Hyphen or period
• A name component within the device name—i.e., a data string between two peri-
ods—must not exceed 63 characters.
• The device name must not begin or end with a hyphen.
• The device name must not begin with the character string "port-xyz" (x, y, z = 0 to 9).
• The device name must not have the form n.n.n.n (n = 0 to 9).
Gateway name assignment is described in chapter 3.5.2.

Configuration Instructions for the LB/FB Remote I/O System

3.5.2 Gateway Configuration
The control panel generally assigns the IP address automatically and assigns it to the gateway
on the basis of the gateway name. If it is a standalone network, you can use the default IP
address and subnet mask specified by the control panel. If the network is a part of an existing
Ethernet company network, obtain the IP address and subnet mask from your network administrator.
Gateway name
In the PROFINET IO system, each device has a unique device name (symbolic name). In the
configuration program, the device name can be automatically assigned using the device name
from the GSDML file and a sequential number. The gateway can only be addressed by the
control panel after the name has been assigned via the configuration software e.g., for transferring project planning data or for exchanging user data in cyclic operation.
IP addresses
Each PROFINET device must have an IP network address to establish an application relationship. There are a number of ways to manage these network IP addresses:
• Configuration during project planning
During project planning of the LB/FB remote I/O system, a range of network addresses is
made available to the configuration program. The configuration program assigns an IP
address to the control panel and the gateway. During system configuration, the control
panel receives a list of IP addresses and assigns these to the individual gateways during
initialization of the application relationships.
• Management by a DHCP server
If the IP addresses are managed by a DHCP server, the IP addresses are requested independently by the individual gateways. When the application relationship is established,
the control panel addresses the gateway using its name to access the IP address
assigned to it.
• Fixed setting
In principle, the network administrator can manage IP addresses manually using the DCP
(Dynamic Configuration Protocol) or a local interface on the field device. This approach
makes it difficult to replace devices as the IP addresses always have to be reentered.

Gateway number
In addition to the gateway name, STEP 7 assigns a device number starting with "1" when the
gateway is plugged in. This device number can be used to identify the gateway in the user program. Unlike the gateway number, the gateway name is not visible in the user program.
Configuring the gateway
The control panel generally assigns the IP address automatically and assigns it to the gateway
on the basis of the gateway name. If it is a standalone network, you can use the default IP
address and subnet mask specified by the control panel. If the network is a part of an existing
Ethernet company network, obtain the IP address and subnet mask from your network administrator. To configure the gateway, proceed as follows:
1.
In the station window, double-click on the symbol name for the gateway (1).

3.5.3 Configuring the I/O Modules
The I/O modules form part of the LB/FB remote I/O system. I/O modules are used to record
measured values and to output signals for process intervention purposes.
The configuration example in these instructions replicates the following hardware arrangement
of an LB/FB remote I/O system:
Figure 3.16 Sample hardware configuration with LB Remote I/O System (FB Remote I/O System
analog)
• LB8122*/FB8222* Gateway
• LB7104*/FB7204* Universal input/output (HART)
• LB7104*/FB7204* Universal input/output (HART)
• LB7104*/FB7204* Universal input/output (HART)
• LB5102*/FB5202* RTD signal converter input
• LB1109*/FB1209* Digital input
• LB2116*/FB2216* Digital output with position feedback
• LB6116*/FB6216* Digital output with shutdown input
• LB6101*/FB6301* Relay output
I/O module groups
One channel of an I/O module is represented by one submodule in STEP 7. The functions of an
I/O module can be specified by subordinating one or more submodules to an I/O module.
The I/O modules are organized by type in the hardware catalog in the Module section. The
channels of the I/O modules are organized in the hardware catalog in the Submodules section.
A distinction is made between three different I/O module groups:
• I/O modules with fixed preassigned input channels or output channels, e.g., 6x01 relay
output. The channels (submodules) of these I/O modules cannot be removed from the
device overview. The submodules of this I/O module group are not listed in the hardware
catalog.
2020-11
• I/O modules without fixed default input channels or output channels, e.g., 5x05 thermo-

Adding I/O modules
To integrate the I/O modules, proceed as follows:
Note
Important information for the integration
The I/O modules are added in the same order as they are positioned on the
backplane. The gateway is placed in slot 0 in advance. You can place your I/O
modules in slot 1 onward.
Note
In the search field (1) of the hardware catalog, you can enter the name of the
I/O module instead of navigating to the I/O module.
Note
Wide I/O modules take up two slots on the backplane. STEP 7 does not
identify wide I/O modules by itself. If you drag a wide I/O module into the
project, leave the slot below empty in the table.

Open the hardware catalog.
2.
Choose your I/O modules from the hardware catalog (2) and drag and drop them into the
configuration table below the gateway (3).
Free slots have a light green background in the table.
Note
When you drag an I/O module into the configuration table, STEP 7
automatically assigns an address range to the I/O module. The address
assignment size (e.g., 2 bytes) is determined by STEP 7 using the GSDML file.
You can change the I/O addresses; see the next section.

3.6 Parameterizing Submodules
Parameterizing allows you to configure the behavior of the I/O modules individually. A submodule represents a channel in an I/O module and determines the function performed by an I/O
module. A distinction is made between the following variants of parameterization:
• Configure measuring behavior: During parameterization of the submodules, the measur-
ing behavior of the I/O modules that process input signals is configured.
• Define measuring limits: You can define measuring limits during parameterization. If these
measuring limits are exceeded or not reached, the gateway sends an alarm to the control
panel.
• Influence output signals: The behavior of I/O modules that emit output signals is also
defined during parameterization. These output signals affect the process.
Parameterizing submodules
To parameterize a submodule, proceed as follows:
1.
Start the PROFINET hardware configuration in your configuration software.
2.
In the configuration table, double-click on a channel of an I/O module (1) that you want to
parameterize.

The Properties – ... window for the channel opens.
3.
Click on the Parameters tab (3).
The parameters input screen for the selected channel opens.
Note
For more information on the parameters and their properties, refer to the
software manual for the PROFINET gateway.
4.
Define the parameter values in the field of the Value column (4).

Diagnosis
4 Diagnosis
You can use the integrated alarm functions in STEP 7 to detect faults. The diagnostics can only
be accessed in online mode.
The gateway detects faults on the following components:
• Backplane
• Gateway
• I/O module
• Channel
• Power supply
Cyclic and acyclic data traffic
If the gateway detects a fault, it transmits fault data and diagnostic data via cyclic and acyclic
data traffic. The gateway transmits fault bits and alarm bits via cyclic data traffic. The gateway
uses the PROFINET alarm function via acyclic data traffic. Alarms are reported when events in
the LB/FB remote I/O system or in the process occur and disappear again.
The following alarm types are sent via acyclic data traffic:
• Diagnostic alarms
Diagnostic alarms relate to faults in LB/FB remote I/O system components, e.g., wire
break on one of the channels.
Diagnostic alarms are transmitted with one of the following priorities: "Fault," "Maintenance required," or "Maintenance demanded." "Fault" has the highest priority. If an event
occurs on a channel that leads to a top-priority diagnostic alarm (fault) (e.g., lead breakage), the corresponding cyclic data is automatically deemed bad via the IO Producer Status (IOPS = Bad) and can no longer be used for the control panel. In such cases, the
control panel must continue processing the faulty input data appropriately in accordance
with its substitute value strategy.
• Process alarms
Process alarms relate to measured values in the process. The limits of measuring ranges
are defined during parameterization of the channels (submodules) in STEP 7. For example, it is possible to define that the gateway should report a process alarm to the control
panel if the measured value of a temperature sensor exceeds 30 °C. For more information
about the parameterization of I/O modules, see chapter 3.6.
• Pull alarms
The gateway transmits pull alarms when an I/O module is pulled out of the backplane.
• Plug alarms
The gateway transmits plug alarms if an I/O module is plugged into the backplane.
Alarms are generated by the gateway and reported to the control panel. If the gateway reports
an alarm, the alarm is always acknowledged by the control panel. Organization blocks (OB) are
available in STEP 7 for further processing of alarms. The organization blocks are triggered by
alarms. For more information about organization blocks, refer to the Siemens AG user documentation.
If you are connecting STEP 7 to the PROFINET network, you can access diagnostic information about faults online.

5 Testing with Variable Tables
You can use variable tables to save different test environments. You can then reproduce tests
and process monitoring multiple times during commissioning or for service purposes.
The following functions are available for testing with variable tables:
• Monitoring of variables
Assign variables to individual submodules to monitor their values.
• Control of variables
Assign fixed values to individual variables.
Note
Controlling output values can result in a potentially dangerous operating state.
These functions should be used exclusively for test purposes or for troubleshooting. For more
information on using these functions, refer to the manual for your configuration software.
The variables that you want to view or control are grouped together in the variable table.
Define the trigger point and the trigger condition to determine when and how often the variables
are monitored or overwritten with values.
5.1 Symbol Table
The symbol table is used to assign a symbolic name and the data type to all absolute
addresses that you address in your subsequent program. These names are valid for your entire
project and are referred to as global symbols. Symbolic programming allows you to improve the
readability of your program.
Creating a symbol table
The process outlined here shows how to modify or redefine symbols via dialog boxes when
compiling your I/O modules in the project.
1.
From the configuration table, select the I/O module to which you wish to assign a symbol.
Right-click on the I/O module (1) and select Edit Symbols (2) from the dialog box.

Note
Data Type
The data type determines the type of signals that the CPU is to process. In this
project, the following data types are used:
• BOOL, BYTE, WORD, DWORD: data of this type are bit combinations. 1
bit (BOOL) to 32 bit (DWORD).
• INT, DINT, REAL: data of this type is available for processing numeric val-
ues (e.g., to calculate arithmetic expressions).
Note
You can add to the symbols automatically from the GSDML file. Click on Add
to Symbol (2).

5.2 Variable Table
You can use the variable table to test the program in the signal memory. The advantage of this
is that you see exactly which signal states are read at the start of the cycle and which are sent
to the modules at the end of the cycle. You can thus distinguish between an error in the program or in the hardware. You can save variable tables for different test environments. You can
therefore reproduce the tests during commissioning, or for service and maintenance purposes.
