Safety instructions Start-up behaviour of the controller
>
WARNING
Danger due to unintentional and dangerous start of machine or plant sections!
► When creating the program, the programmer must ensure that no unintentional and dangerous
start of machines or plant sections after a fault (e.g. e-stop) and the following fault elimination can
occur!
Realise restart inhibit.
► In case of an error, set the outputs concerned to FALSE in the program!
2.3 Start-up behaviour of the controller
6827
15233
11575
A restart can, for example, be caused by:
• Voltage restoration after power failure
• Reset after the watchdog responded because the cycle time was too long
• Error elimination after an E-stop
To ensure safe controller behaviour:
► monitor the voltage supply in the application program.
► In case of an error switch off all relevant outputs in the application program.
► Additionally monitor actuators which can cause hazardous movements in the application program
(feedback).
► Monitor relay contacts which can cause hazardous movements in the application program
(feedback).
► If necessary, ensure that welded relay contacts in the application project cannot trigger or continue
hazardous movements.

WARNING
The user is responsible for the reliable function of the application programs he designed. If necessary,
he must additionally carry out an approval test by corresponding supervisory and test organisations
according to the national regulations.
Bootloader
14111
On delivery ecomatmobile controllers only contain the boot loader.
The boot loader is a start program that allows to reload the runtime system and the application
program on the device.
The boot loader contains basic routines...
• for communication between hardware modules,
• for reloading the operating system.
The boot loader is the first software module to be saved on the device.
>
Runtime system
14112
Basic program in the device, establishes the connection between the hardware of the device and the
application program.
→ chapter Software modules for the device (→ p. 16)
On delivery, there is normally no runtime system loaded in the controller (LED flashes green at 5 Hz).
Only the bootloader is active in this operating mode. It provides the minimum functions for loading the
runtime system, among others support of the interfaces (e.g. CAN).
Normally it is necessary to download the runtime system only once. Then, the application program can
be loaded into the controller (also repeatedly) without affecting the runtime system.
The runtime 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:
→ www.ifm.com
>
Application program
15274
14118
Software specific to the application, implemented by the machine manufacturer, generally containing
logic sequences, limits and expressions that control the appropriate inputs, outputs, calculations and
decisions.
The visualisation pages and embedded graphics are part of the CODESYS application program.

3.4.2 Programming notes for CODESYS projects
Here you receive tips how to program the device.
► See the notes in the CODESYS programming manual.
>
FB, FUN, PRG in CODESYS
In CODESYS we differentiate between the following types of function elements:
FB = function block
• An FB can have several inputs and several outputs.
• An FB may be called several times in a project.
• An instance must be declared for each call.
• Permitted: Call FB and FUN in FB.
FUN = function
• A function can have several inputs but only one output.
• The output is of the same data type as the function itself.
PRG = program
• A PRG can have several inputs and several outputs.
• A PRG may only be called once in a project.
• Permitted: Call PRG, FB and FUN in PRG.

Background:
All variables of functions...
• are initialised when called and
• become invalid after return to the caller.
Function blocks have 2 calls:
• an initialisation call and
• the actual call to do something.
Consequently that means for the function block call in a function:
• every time there is an additional initialisation call and
• the data of the last call gets lost.

NOTICE
Risk that the device acts too slowly!
Cycle time must not become too long!
► When designing the application program the above-mentioned recommendations must be
complied with and tested.
► If necessary, the cycle time must be optimised by restructuring the software and the system
set-up.
Note the cycle time!
For the programmable devices from the controller family ecomatmobile numerous functions are
available which enable use of the devices in a wide range of applications.
As these units use more or fewer system resources depending on their complexity it is not always
possible to use all units at the same time and several times.
>
Important note to program the device
Applies to the following devices:
• BasicController relay CR0431
► For the time of programming interconnect the connections B:1 (VBB15) and B:8 (VBBs).
Otherwise programming is not possible.
Background:
The controller resets all outputs when programming begins, also SUPPLY_SWITCH.
Without VBB15 the controller would be separated from the voltage supply and is switched off.
When the controller is switched on again, the device is in bootloader mode.
The programmer has to load the Basic System to the device again.
Then reload the application program to the device.

Creating application program
The application program is generated by the CODESYS 2.3 programming system and loaded in the
controller several times during the program development for testing:
In CODESYS: [Online] > [Login] > load the new program.
For each such download via CODESYS 2.3 the source code is translated again. The result is that
each time a new checksum is formed in the controller memory. This process is also permissible for
safety controllers until the release of the software.

Using ifm maintenance tool
8492
The ifm Maintenance Tool serves for easy transfer of the program code from the programming station
to the controller. As a matter of principle each application software can be copied to the controllers
using the ifm Maintenance Tool. Advantage: A programming system with CODESYS licence is not
required.
Here you will find the current ifm Maintenance Tool:
Homepage → www.ifm.com
>
Distribution of the application program
8493
We recommend the following sequence, if the application software is to be copied to the series
machine and used:
Saving the software
After completion of program development the latest version of the application program loaded in
the controller using the ifm Maintenance Tool has to be read from the controller and saved on a
data carrier using the name project_file.RESX. Only this process ensures that the application
software and its checksums are stored.
Download of the software.
To equip all machines of a series production with an identical software only this file may be loaded
in the controllers using the ifm Maintenance Tool.
An error in the data of this file is automatically recognised by the integrated checksum when
loaded again using the ifm Maintenance Tool.

3.4.3 Operating states
After power on the ecomatmobile device can be in one of five possible operating states:
• BOOTLOADER
• INIT
• STOP
• RUN
• SYSTEM STOP
>
INIT state (Reset)
Premise: a valid runtime system is installed.
This state is passed through after every power on reset:
> The runtime 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 orange.
Change out of this state possible into one of the following states:
• RUN
• STOP

STOP state
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.
A transition from this state into one of the following states is possible:
• RUN
• ERROR
• FATAL ERROR
• INIT (after power-on-reset)
>
RUN state
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 application program exists.
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 application program is running.
> The LED flashes green with 2 Hz.
The LED can be controlled differently by the application program → FB SET_LED (→ p. 172).
A transition from this state into one of the following states is possible:
• INIT (after power-on-reset)
• STOP
• ERROR
• FATAL ERROR

3.4.4 Performance limits of the device
>
Watchdog behaviour
In this device, a watchdog monitors the program runtime of the CODESYS application.
If the maximum watchdog time (application program: 100 ms; visualisation: 1 200 ms) is exceeded:
> the device changes to the "Timeout Error" state
> all processes are stopped (reset)
> all outputs are switched off
> the screen goes black
> the status LED flashes red at 10 Hz
Eliminate the fault:
Delete application program!
PowerOn Reset
Reload the application program into the device
If the watchdog in question fails:
> a second watchdog leads the device to the state "Fatal Error"
> the status LED lights red
Eliminate the fault:
PowerOn Reset
If unsuccessful:
Goto Bootloader
PowerOn Reset
Reload the runtime system into the device
Reload the application program into the device
If unsuccessful:
Hardware error: return device to ifm!

Visualisation limits
Embedded displays, used e.g. in ecomatmobile devices, cannot provide the full colour scope of
bitmap graphics because the available power reserves are restricted. Nevertheless, the following
preparations enable bitmap images in the device:
Correct selection of the motifs,
clever shifting of colours or
clever compilation of a colour palette and
the correct scaling of the bitmaps before using them in the device.
Performance limits of the device (→ p. 25)
Table: specifications for the start image
The graphics used in the project may be larger than the specified image size. In this case, however,
only a (selectable) section of the image will be visible.
Colours:
The device supports 28 (= 256) colour nuances.
► Create bitmap (BMP) with 256 colours:

>
Resample / scale image
If an image is loaded in the device which does not meet the requirements for size or colour, it is
resized before it is displayed and the colours used are "checked".
Each time the image is opened, it must be resampled. This often leads to much longer times to
change from one image to the other. Corrective measures:
► First carry out all transformations of the bitmap or the image in an image processing program on
your computer.
Only for BasicDisplay: The colour palette is adapted when the image is integrated into the project
by CODESYS. On the device itself no adaptations will be made (size, scaling, colour).
► Only save the suitably transformed images in the visualisation of the device.

FIFO (First In, First Out) = Operating principle of the stack memory: The data packet that was
written into the stack memory first, will also be read first. Each identifier has such a buffer (queue).
Some Raw-CAN function elements enable transmitting and receiving of several messages in one PLC
cycle as the messages are temporarily stored in a FiFo:
- CAN_TX..., → Function elements: transmit RAW-CAN data
- CAN_RX_ENH_FIFO (→ p. 62)
- CAN_RX_RANGE_FIFO (→ p. 66)
The number of FIFo messages is limited. The following limitations of the devices are valid:
