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 control perfor-
mance
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. The Inline controller has 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, e.g., nec-
essary 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.
PROFINET device
functionality
The PROFINET protocol can be used via the Ethernet interfaces of the Inline controller. In
this case, the Inline controller can be used as a PROFINET device.
Modbus functionality The Modbus TCP/UDP communication protocol can be used via the Ethernet interfaces of
the Inline controller. In this case, the Inline controller can be used as a Modbus client. 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 Inline
controller. The controller supports the MRP client function, which can be enabled or dis-
abled via PC Worx as an option. This function is disabled by default. If the function is en-
The ILC 191 ME/AN and ILC 191 ME/INC Inline controllers have the same appearance
and numerous identical functions.
The main differences between the Inline controllers are connectors 6 (ILC 191 ME/AN:
analog inputs, ILC 191 ME/INC: counter inputs) and 7 (ILC 191 ME/AN: analog outputs,
ILC 191 ME/INC: incremental encoder inputs), see from page 51 onwards.
In the following, the term Inline controller is used in general. Differences between the con-
trollers are particularly mentioned where necessary.
For information on how to configure the Inline controller as a PROFINET device in the
PC Worx software, please refer to Section “The Inline controller as a PROFINET device”
on page 63.

ILC 191 ME/X
12 PHOENIX CONTACT 8607_en_03
abled, it remains enabled after the supply voltage is switched off and on. If the controller has
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 ex-
pected.
Integrated INTERBUS
connection
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+ diagnostic tool or to communicate with serial I/O devices
via function blocks.
RS-485/RS-422 interface An RS-485 network with several I/O devices can be created via the RS-485/RS-422 inter-
face. The interface is operated in PC Worx via the RS485_422_INIT,
RS485_422_RECEIVE, and RS485_422_SEND function blocks, see Section “Function
blocks for RS-485/RS-422 communication” on page 87.
Parameterization
memory/SD card
The Inline controller 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, e.g., the visualization project.
The plug-in parameterization memory is optional and is not required in order to operate the
Inline controller.
The Inline controller cannot be programmed via the RS-232 interface.
The parameterization memory is not supplied as standard with the Inline controller.
Only use a parameterization memory provided by Phoenix Contact (for ordering data, see
Section “Accessories” on page 154).
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.

The Inline controller can be used as a distributed controller of an Inline station which is con-
nected to an Ethernet system. A single Inline local bus (Figure 2-1) as well as a complete
INTERBUS system with a maximum of 4 remote bus levels (Figure 2-2) can be connected
to the Inline controller.

2.2.2 The Inline controller for position control
The Inline controller offers Ethernet, RS-485, and pulse direction interfaces. This means
that electric motors can be driven via frequency inverters or other power electronics. Axis
limit switches and home position switches are connected directly to the Inline controller.
Analog inputs (ILC 191 ME/AN) are available for the position detection of a tool using a laser
measuring system, for example. The ILC 191 ME/INC has digital inputs for incremental en-
coders.

2.2.4 Applicative system redundancy using the Inline controller
The following figure shows an example of applicative system redundancy. The example
shows a PROFINET device with control function (ILC 191 ME/AN) 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.

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 60079-15:2012.
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 by an approved controller of the same type.
Repairs may only be performed by the manufacturer. The manufacturer is not liable for
harm 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, which 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. For reliable 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 191 ME/X
18 PHOENIX CONTACT 8607_en_03
7. For safe operation with the plug-in parameterization memory, it must be completely
plugged and snapped in.
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 Inline controller, unpack and pack the controller in ac-
cordance with the ESD regulations.
