he must additionally carry out an approval test by corresponding supervisory and test organisations
according to the national regulations.
3.3 PLC configuration
1797
The control system ecomatmobile is a device concept for series use. This means that the devices
can be configured in an optimum manner for the applications. If necessary, special functions and
hardware solutions can be implemented. In addition, the current version of the ecomatmobile
software can be downloaded from our website at: www.ifm.com.
Setup the target (→page 18)
Before using the devices it must be checked whether certain functions, hardware options, inputs and
outputs described in the documentation are available in the hardware.

4.1 Operating states
1075
After power on the ecomatmobile controller can be in one of five possible operating states:
4.1.1 INIT state (Reset)
1076
This state is passed through after every power on reset:
> The operating system is initialised.
> Various checks are carried out, e.g. waiting for correctly power supply voltage.
> This temporary state is replaced by the RUN or STOP state.
> The LED lights yellow.
Change out of this state possible into one of the following states:
RUN
FATAL ERROR
STOP
4.1.2 RUN state
8287
A transition into this state is possible in the following cases:
from the INIT state (autostart) if the following conditions are met:
The operating voltage has reached a minimum value. AND:
The IEC application regularly runs cyclically.
From the STOP state:
via the CoDeSys command RUN.
The operating voltage has reached or exceeded a minimum value.
In the RUN state:
> The runtime system is running.
> The operating system is running.
> The application program is running.
> The LED flashes green with 2 Hz.
> The LED can be controlled differently by the application program.

A transition from this state into one of the following states is possible:
STOP
ERROR
FATAL ERROR
INIT (after power-on-reset)
4.1.3 STOP state
8288
A transition into this state is possible in the following cases:
from the INIT state if no application program is loaded.
From the RUN state if the following condition is met:
The STOP command is sent via the CoDeSys interface.
In the STOP state:
> The outputs of the device are switched off.
> Processing of the application program is stopped.
> The LED lights green.
If no operating / run time system is loaded: The LED flashes green with 5 Hz.
A transition from this state into one of the following states is possible:
RUN
ERROR
FATAL ERROR
INIT (after power-on-reset)
4.1.4 ERROR state
8290
A transition into this state is possible in the following cases:
if the supply voltage is too low.
In the ERROR state:
> The outputs of the device are switched off.
> Processing of the application program is stopped.
> System parameters are saved.
> The LED flashed red with 5 Hz.
A transition from this state into one of the following states is possible:
RUN
STOP
FATAL ERROR
INIT (after power-on-reset)

A transition into this state is possible in the following cases:
memory error (RAM / Flash)
exception error
operating system error
In the FATAL ERROR state:
> The outputs of the device are switched off.
> The application program is terminated.
> The runtime system is terminated.
> The LED lights red.
A transition from this state into one of the following states is possible:
INIT (after power-on-reset)
4.2 Status LED
7998
The operating states are indicated by the integrated status LED (default setting).
LED colour Flashing frequency Description
Off permanently off no operating voltage
Green 5 Hz no operating system loaded
Green 2 Hz RUN state
Green permanently on STOP state
Red 5 Hz application stopped due to undervoltage
Red permanently on FATAL ERROR or STOP state with error
Yellow/orange briefly on INIT state, reset checks
The operating states STOP and RUN can be changed by the programming system.
With this controller the status LED can also be set in the application program. This can be done by
SET_LED (→page 230).
NOTE
The use of the LED function block in the application program replaces the system setting of the LED in
the RUN state.

4.3.1 Load the operating system
8486
On delivery of the ecomatmobile controller no operating system is normally loaded (LED flashes
green at 5 Hz). Only the boot loader is active in this operating mode. It provides the minimum functions
for loading the operating system (e.g. RS232, CAN).
Normally it is necessary to download the operating system only once. The application program can
then be loaded to the controller (also several times) without influencing the operating system.
Advantage:
The operating system is provided with this documentation on a separate data carrier. In addition, the
current version can be downloaded from the website of ifm electronic gmbh at:
www.ifm.com > select your country > [Service] > [Download] > [Control systems]
NOTE
The software versions suitable for the selected target must always be used:
operating system (CRnnnn_Vxxyyzz.RESX),
PLC configuration (CRnnnn_Vxx.CFG),
device library (ifm_CRnnnn_Vxxyyzz.LIB )

The basic file name (e.g. "CR0401") and the software version number "xx" (e.g. "01") must always have

The values for "yy" (release number) and "zz" (patch number) do not have to match.
IMPORTANT: the following files must also be loaded:
the internal libraries (created in IEC 1131) required for the project,
the configuration files (*.CFG)
and the target files (*.TRG).
The operating system is transferred to the device using the separate program "Maintenance Tool".
(The downloader is on the ecomatmobile DVD "Software, tools and documentation" or can be
downloaded from ifm's website, if necessary).
Normally the application program is loaded to the device via the programming system. But it can also
be loaded using the "Maintenance Tool" if it was first read from the device upload).

When creating a new project in CoDeSys®the target file corresponding to the controller must be
loaded. It is selected in the dialogue window for all hardware and acts as an interface to the hardware
for the programming system.
Figure: Target system settings
At the same time, all important libraries and the PLC configuration are loaded when selecting the
target. These can be removed by the programmer or complemented by further libraries, if necessary.
NOTE
The software versions suitable for the selected target must always be used:
operating system (CRnnnn_Vxxyyzz.H86 / CRnnnn_Vxxyyzz.RESX)
PLC configuration (CRnnnn_Vxx.CFG)
device library (ifm_CRnnnn_Vxxyyzz.LIB )
and the further files (chapter Overview of the files and libraries used (→page 236))
CRnnnn
Vxx: 00...99
yy: 00...99
zz: 00...99
device article number
target version number
release number
patch number
The basic file name (e.g. "CR0032") and the software version number "xx" (e.g. "02") must always have
the same value! Otherwise the device goes to the STOP mode.
The values for "yy" (release number) and "zz" (patch number) do not have to match.
IMPORTANT: the following files must also be loaded:
the internal libraries (created in IEC 1131) required for the project,
the configuration files (*.CFG)
and the target files (*.TRG).

During the configuration of the programming system (previous section) automatically also the PLC
configuration was carried out.
The point [PLC Configuration] is reached via the tab [Resources]. Double-click on [PLC Configuration]
to open the corresponding window.
►Click on the tab [Resources] in CoDeSys:
►Double-click on [PLC Configuration] in the left column.

Configurations Set up programming system
Based on the configuration the following is available in the program environment for the user:
All important system and error flags
Depending on the application and the application program, these flags must be processed and
evaluated. Access is made via their symbolic names.
The structure of the inputs and outputs
These can be directly symbolically designated (highly recommended!) in the window [PLC
Configuration] (example figure below) and are available in the whole project as [Global
Variables].
