1.3 General safety notes
Observe the country-specific installation, safety, and accident prevention regulations.
During startup and maintenance work, proceed in accordance with the five safety rules of
DIN EN 50110-1. In general, the rules should be observed in the specified order:
– Disconnect safely
– Ensure power cannot be switched on again
– Verify safe isolation from the supply
– Ground and short circuit
– Cover or safeguard adjacent live parts
Once the work is complete, perform the above steps again in reverse order.
1.4 Intended use
The Inline controller is a modular small-scale controller that can be used for small and me-
dium-size applications. The device corresponds to IP20 protection and can be used in
closed control cabinets or in control boxes (terminal boxes) with IP54 protection or higher.
This device is designed for use in industrial environments.
1.5 Disposal
NOTE:
The IP20 degree of protection (IEC 60529/EN 60529) of the device is intended for a clean
and dry environment. Do not subject the device to mechanical and/or thermal loads that
exceed the specified limits.
NOTE: Risk of unauthorized network access
Connecting devices to a network via Ethernet always entails the risk of unauthorized ac-
cess to the network.
Please check your application for any option of deactivating active communication chan-
nels (for instance SNMP, FTP, BootP, DCP, etc.), or setting passwords to prevent third
parties from unauthorizedly accessing the controller and modifying the system.
With regard to the controller's communication interfaces, we recommend not to use the
controller in safety-critical applications unless using additional security devices.
So, please take additional protective measures according to the IT security requirements
and the standards applicable to your application (for instance virtual networks (VPN) for
remote maintenance access, firewalls, etc.) for protection against unauthorized network
access.
For the protection of networks for remote maintenance via VPN, Phoenix Contact offers
the mGuard product series security devices which you can find described in the latest
Phoenix Contact catalog (phoenixcontact.net/products).
Do not dispose of the device with household waste, it should instead be disposed of in
accordance with the currently applicable national regulations. The device can also be re-
turned to Phoenix Contact.

2 Description of the Inline controller
2.1 General description of the Inline controller
The Inline controller is a modular small-scale controller with integrated Ethernet and
INTERBUS connections.
IEC 61131 controller per-
formance
The Inline controller is consistently configured and programmed in accordance with
IEC 61131 using the PC Worx automation software. PC Worx can be operated via the net-
work (Ethernet). The powerful processor can be programmed in all five IEC 61131 program-
ming languages and ensures quick control task processing.
Integrated Ethernet con-
nection
The integrated Ethernet connection (via twisted pair cable) ensures Ethernet connectivity.
Throughout the Ethernet network, the Inline controller can be accessed via TCP/IP or
UDP/IP. A standardized Ethernet interface is available for each of the ILC 131 ETH,
ILC 151 ETH, ILC 131 ETH/XC and ILC 151 ETH/XC Inline controllers. The
ILC 171 ETH 2TX and ILC 191 ETH 2TX controllers have two fully implemented Ethernet
connections, which are switched inside the device.
Integrated communication functions enable direct and effective data exchange via Ether-
net. The Ethernet network provides universal options for communicating with the Inline con-
troller. Using the IP_USEND and IP_URCV communication blocks, information, such as re-
quired coupling variables, can be exchanged between Inline controllers via Ethernet. This
enables distributed, modular automation solutions to be configured.
The existing IEC 61131-5 blocks have therefore been extended to include a transparent
TCP/IP mode and a transparent UDP/IP mode.
When using the AX OPC server provided in the AUTOMATIONWORX Software Suite Ver-
sion 1.30 or later, Inline controller data is available in the Ethernet network in a standardized
format and can be used for the different visualization packages.
The ILC 131 ETH, ILC 151 ETH, ILC 171 ETH 2TX, ILC 191 ETH 2TX, ILC 131 ETH/XC,
and ILC 151 ETH/XC Inline controllers have the same appearance and numerous identi-
cal functions.
The main difference lies in the varying memory sizes, which are available to the user.
The ILC 171 ETH 2TX and ILC 191 ETH 2TX Inline controllers also have a second Ether-
net interface.
The ILC 131 ETH/XC and ILC 151 ETH/XC Inline controllers are approved for use under
extreme ambient conditions. Observe the notes in Section “Ambient conditions” on
page 93 and in Section “Tested successfully: use under extreme ambient conditions” on
page 101.
In the following, the term Inline controller is used in general. Differences between the con-
trollers are explicitly mentioned where necessary.
For additional information about the different memory sizes, please refer to Section 5.1,
“Technical data”.

ILC 1X1
12 PHOENIX CONTACT 8385_en_02
PROFINET device
functionality
The PROFINET protocol can be used via the Ethernet interfaces of the Inline controllers. In
this case, the Inline controllers can be used as a PROFINET device. All the Inline controllers
listed in Section 1.1 support this function from hardware version “01”/firmware version
“4.10” or later together with the PC Worx software version 6.20 Service Pack 1 or later.
Modbus functionality The Modbus/TCP (UDP) communication protocol can be used via the Ethernet interfaces
of the Inline controller. The Inline controller can be used as a Modbus/TCP client and/or as
a Modbus/TCP server (as of firmware version 4.40 and
AUTOMATIONWORX Software Suite Version 1.82 AddOn V1).
For additional information, please refer to the AH EN MODBUS TCP application note.
MRP The Media Redundancy Protocol MRP can be used via the Ethernet interfaces of the
ILC 171 ETH 2TX and ILC 191 ETH 2TX Inline controllers. The controllers support the MRP
client function, which can be enabled or disabled via PC Worx as an option. This function is
disabled by default. If the function is enabled, it remains enabled after the supply voltage is
switched off and on. If the controllers have been reset to the delivery state, the MRP client
function will also be disabled again. In a ring with Media Redundancy Protocol, maximum
switch-over times of up to 200 ms can be expected.
Integrated INTERBUS con-
nection
An Inline local bus as well as an INTERBUS remote bus can be connected via the
INTERBUS connection. In this way you can create a complete INTERBUS system (maxi-
mum of 4 remote bus levels) using the Inline controller as a distributed controller.
The I/O level is connected to the Inline controller via INTERBUS.
RS-232 interface This interface can be used to either assign the IP address of the Inline controller and to ac-
cess the controller using the Diag+ diagnostics tool or to communicate with serial I/O de-
vices via function blocks.
Parameterization memo-
ry/SD card
All Inline controllers can be operated using a plug-in parameterization memory in the form
of an SD card. This memory can be used to save programs and configurations which belong
to your project.
The plug-in parameterization memory is optional and is not required in order to operate the
Inline controller.
For information on how to configure the Inline controllers as a PROFINET device in the
PC Worx software, please refer to Section “The Inline controller as a PROFINET device”
on page 49.
Please note: the ILC 131 ETH and ILC 131 ETH/XC controllers do not support connection
of the INTERBUS remote bus.
The Inline controller cannot be programmed via the RS-232 interface.
The parameterization memory is not supplied as standard with the Inline controllers.
Only use a parameterization memory provided by Phoenix Contact (for ordering data, see
Section “Accessories” on page 95).
NOTE: Parameterization memory (SD card) – formatting note
The SD card is already formatted and is intended for use with Phoenix Contact devices.
Make sure that the SD card is not reformatted.

2.2.4 Applicative system redundancy with ILC 171 ETH 2TX or
ILC 191 ETH 2TX
The following figure shows an example of applicative system redundancy. The example
shows a PROFINET device with control function (ILC 171 ETH 2TX) that is connected to a
PROFINET network by means of a switch. Identical application programs run on both
higher-level PROFINET controllers. To achieve synchronization, both PROFINET control-
lers are connected via an Ethernet connection by means of a switch. PROFINET controller
A operates as primary controller, PROFINET controller B operates as backup controller.
The ILC 191 ETH 2TX also supports applicative system redundancy.

2.3 Notes on using the Inline controller in potentially
explosive areas
Approval according to directive 94/9/EC
II 3G Ex nA IIC T4 Gc X
Installation notes
1. The Inline controller conforms to the requirements of protection type “n” and can be in-
stalled in a zone 2 potentially explosive area. The Inline controller is a category 3G item
of electrical equipment.
The Inline controller meets the requirements of EN 60079-0:2009 and
EN 60079-15:2010.
2. The Inline controller must only be installed, started up, and maintained by qualified spe-
cialist personnel.
3. Please follow the installation instructions given in the user manual and the package slip.
4. When installing and operating the device, the applicable safety directives (including na-
tional safety directives), accident prevention regulations, as well as general technical
regulations must be observed.
5. For the safety data, please refer to the corresponding documentation (user manual,
package slip) and the certificates (declaration of conformity and other approvals, if ap-
plicable).
6. Access to the circuits inside the Inline controller is not permitted. Do not repair the Inline
controller yourself but replace it with an approved controller of the same type.
Repairs may only be performed by the manufacturer. The manufacturer is not liable for
damage resulting from noncompliance.
7. The IP20 (EN 60529) degree of protection for the device is designed for a clean and dry
environment.
8. Do not subject the Inline controller to mechanical strain and/or thermal loads that ex-
ceed the limits specified in the product documentation.
9. The Inline controller is not designed for use in potentially dust-explosive atmospheres.
If dust is present, install the device in suitable, approved housing. Please note the sur-
face temperature of the housing.
Installation in zone 2
1. Observe the specified conditions for use in potentially explosive areas.
2. Install the device in a suitable approved housing (with at least IP54 protection according
to EN 60529) that meets the requirements of EN 60079-15.
3. In potentially explosive areas, only snap the device onto the DIN rail and remove it from
the DIN rail and connect and disconnect the cables when the power is disconnected.
4. Connect the DIN rail to protective earth ground.
5. Only connect devices to the supply and signal circuits in zone 2 that are suitable for op-
eration in potentially explosive areas of zone 2 and for the conditions at the installation
location.
6. To ensure safe operation, the RJ45 connector needs to have a fully functioning locking
clip. Repair any damaged connectors immediately.
WARNING: Explosion hazard
Make sure that the following notes and instructions are observed.

ILC 1X1
18 PHOENIX CONTACT 8385_en_02
7. For safe operation with the plug-in parameterization memory (SD card), this must be
fully plugged and snapped in. In potentially explosive areas, use the SD card as main
memory only. Don't insert or remove the SD card during operation.
8. The programming interface may only be used if there is no potentially explosive atmo-
sphere.
Restrictions/limit values
1. Only Inline terminals that are approved for use in potentially explosive areas
may be snapped next to the Inline controller.
Before using the Inline terminal in a zone 2 potentially explosive area, check whether
this Inline terminal has been approved for installation within this area.
For a list of terminals that are approved for zone 2 potentially explosive areas, please
refer to the AH EN IL EX ZONE 2 application note.
2. Please make sure that the maximum permissible current of 4 A flowing through poten-
tial jumpers UMand US(total current) is not exceeded when using the Inline controller
in potentially explosive areas.
3. Also make sure that the maximum permissible current of 2 A flowing through potential
jumper ULis not exceeded.
4. The maximum permissible current for each spring-cage contact is 2 A.
2.4 Unpacking the Inline controller
The Inline controller is supplied in an ESD bag together with a package slip with installation
instructions. Read the complete package slip carefully before unpacking the Inline control-
ler.
NOTE: Electrostatic discharge
The Inline controller contains components that can be damaged or destroyed by electro-
static discharge. When handling the Inline controller, observe the necessary safety pre-
cautions against electrostatic discharge (ESD) according to EN 61340-5-1 and
IEC 61340-5-1.
NOTE:
To avoid possible damage to the module, unpack and pack the Inline controller in accor-
dance with the ESD regulations.
