3 General description
The requirements regarding modern
machinery and equipment are constantly
growing. System transparency, remote
maintenance and remote access are
getting more and more important in
international competition. Early notification
in the event of any disturbances and a
fast response to current problems will
increase system availability, save costs
and improve the overall stability of the
production process.
E-T-A provides the ideal solution for
machine and panel builders with the
intelligent protection system comprising
the REX12D circuit protector and the
intelligent EM12D-TIO supply module. The
system combines the well-proven quality
of DC24V overcurrent protection with
the communication options of the IO link
system. It allows complete transparency
of the DC24V power supply and provides
all necessary information for a reliable
production process in this plant sector.
Part of the information is the permanent
transmission of status indication regarding
each channel of the individual circuit
protector. In addition the present load
current of the channel on the selected
circuit protector is transmitted to the IO
link master.
A parameterisable limit value allows
creation of a warning threshold which
advises the user of changing system
conditions.
Any number of the only 12.5 mm wide
modules can be mounted side by side.
They feature push-in technology with
press release buttons and allow no-tool
time-saving and maintenance-free wiring.
The supply module is designed for DC
24 V and 40 A and accommodates max.
10 mm² with wire end ferrule as a plus (+)
supply. On the load output side the circuit
protector can be wired with 2.5 mm².
It is exactly tailored to the needs of
machine and panel builders. And what
is more: no additional accessories are
required when connecting the individual
components electrically and mechanically.
This helps save time and money!

3.1 Design of the entire system
The EM12D-TIO intelligent supply module is the centre of the
ControlPlex®system. It collects all information of the REX12D
electronic circuit protectors and forwards it to the superordinate
IO link master and thus to the superordinate control unit.
The IO link interface to the superimposed IO link master is
realised with a 3-wire cable. It allows connection of the required
IO link master to the ControlPlex®system, thus enabling display
and analysis of the individual measuring values as well as
diagnosis and control of the individual channels of the electronic
circuit protectors. This enables the user to have unrestricted
access to the safety-relevant functions even in the event of
an interruption. Any occurring failures will be detected quickly
and can be remedied without delay. The ControlPlex®system
effectively reduces system downtimes and significantly increases
the productivity.

5 Operating modes and signalling
5.1 Operating mode: (system start)
When applying the supply voltage, the EM12D-TIO intelligent
supply module will be initialised. The device will carry out
implemented programme memory tests and self test routines.
During this time a communication via the interfaces is not
possible.
5.2 Operating mode: (critical failure)
If a failure is detected during the self test routines, the EM12D-TIO
intelligent supply module will change into operating mode »Critical
Failure«. In the event of a critical failure, the device will also
change into this operating mode. This operating mode can only
be discontinued by way of re-starting the device and it prevents
the data exchange via the interfaces. If the EM12D-TIO intelligent
supply module is in this operating mode, no communication is
possible with the superordinate control unit. The electronic circuit
protectors cannot be controlled by it and remain OFF.
5.3 Operating mode: (non-critical failure)
If there are invalid or no configuration data at all available in
the EM12D-TIO intelligent supply module, it will change into
the this operating mode. This operating mode only allows
restricted non-cyclical data exchange. Cyclical data exchange
is prevented. This operating mode will be left upon receipt of
the correct module and slot parameters and configuration data.
The circuit protectors remain OFF.
5.4 Operating mode: (independent
operation)
If no connection to the superordinate control unit is recognised
after the supply voltage was applied, the module will change
into the operating mode »independent operation«. Thus the
parameters stored in the EM12D-TIO will be transmitted to the
electronic circuit protectors. If there is a connection between the
EM12D-TIO and the superordinate IO link master and there is no
critical failure, the operating mode »independent operation«will
be quitted. Should the connection between the EM12D-TIO and
the superordinate control unit be interrupted during operation,
the EM12D-TIO will automatically change into the operating
mode »independent operation«.
By means of the non-cyclical parameter, the behaviour of the
EM12D-TIO can be defined in the event of an interruption of the
superordinate IO link master. Either the condition of the circuit
protector is frozen (FREEZE) or all circuit protectors are switched
off (UNFREEZE).
Should the connection between the EM12D-TIO and the
superordinate IO link master be interrupted and the non-cyclical
parameter unfreeze be set, all circuit protectors will be switched
off before changing into the operating mode »independent
operation«.
Should the connection between the EM12D-TIO and the
superordinate IO link master be interrupted and the non-cyclical
parameter »FREEZE«be set, the condition of the circuit protectors
will remain unchanged before changing into the operating mode
»independent operation«.
Should the connection between the IO link device and the
superordinate IO link master be restored after a previous
interruption, the EM12D-TIO will automatically change into the
operating mode »faultless operation«.
5.5 Operating mode: (faultless operation)
If there is no fault and a connection is in place to the superordinate
IO link master, the EM12D-TIO will change into the operating
mode »faultless operation«.
The parameters will be transmitted from the superordinate IO
link master to the EM12D-TIO and be saved there. Subsequently
they will be forwarded to the electronic circuit protectors. The
configuration data and the parameters will be exchanged as
non-cyclical data between the IO link master (superordinate
control) and the EM12D-TIO.

15
fig. 11: Cycle time of the system
6 Basic functionalities of the entire system
6.1 Internal cycle time
The cycle time via the ELBus®is 340 ms. During the aforementioned period, the status and the load current of each circuit protector
are cyclically transmitted to the EM12D-TIO intelligent supply module.
6.2 Hot swap of circuit protectors
The electronic REX12D circuit protector can at any time be mounted side by side with a supply module or an existing system.
By closing the connector arm, a voltage supply of the device is available. Also, the device is connected to the internal ELBus®.
Opening the connector arm is only permitted in the OFF condition. Opening under load can damage the device or cause
undefined system conditions.
After plugging in a circuit protector, it will automatically be identified and parameterised if parameters are available for the slot in
question. During this procedure the cyclical data will be marked as unvalid for a short period of time.
6.3 Communication via port configuration tool
The port configuration tool is made available by the manufacturer of the IO link master.
It allows direct access of the IO link master to the IO link device EM12D-TIO. Thus it is possible to parameterise the individual
devices, indicate the status and receive diagnostic information.
If the slot parameters are changed, the change will be signalled to the superordinate control unit via the IO link master. The user
will thus be able to process these changes in his control unit accordingly.
The cycle times indicated refer to REX12D units from index I onwards.
Cyclical Data 16 x 15 ms = 240 ms Non-cyclical Data 100 ms

7 Communication types
7.1 SIO mode, group signal at PLC input
Commencing with revision F, the SIO mode is available in the supply module.
It is possible to connect the EM12D-TIO directly to a PLC input. In this case, it is not the IO link information that is going to be
transmitted, but only the group status signal.
The data line IO link C/Q to X81 carries a high signal if no circuit circuit protector has tripped. As soon as a circuit protector trips,
the data line IO link C/Q to X81 carries a low signal.
Trip is acknowledged via the momentary switch on the circuit protector in question.
7.2 Model of the EM12D-TIO intelligent supply module
The EM12D-TIO has an internal ELBus® interface enabling the communication with the electronic REX12D circuit protector. There
are two different models of the supply module. The choice of the model in question is determined by the IODD used.
7.2.1 Models for the operation of 32 channels
Up to 16 devices with max. 32 channels can be connected to the supply module. Only the status is transmitted cyclically with this
model. It accommodates both REX12D-Tx1 (1-channel) circuit protectors or REX12D-Tx2 (2-channel) or even a combination of both.
7.2.2 Models for the operation of 16 channels
Up to 16 channels can be connected to the supply module. This extended version not only provides cyclical transmission of the
status, but also the present current of the load circuits. Due to the limited transmission width with IO link of 32 bytes, the number
of channels is limited to 16 due to the higher number of data to be transmitted. The model accommodates both REX12D-T1
(1-channel) circuit protectors or REX12D-Tx2 (2-channel) or a combination of both.
7.2.3 Population errors
If a double channel device is connected as channel 16/17 or 32/33, the control unit will receive the information that a device is
available at channel 16 or 32.
When reading out the Cominfo of the circuit protector, a message will be received saying that the circuit protector has wrong
parameters.
The channels cannot be operated (cannot be switched on).
7.2.4 Error device addressing
Due to mechanical problems, there may be addressing errors. This will become evident as follows: some channels are OFF after
applying voltage. They cannot even be switched on by means of the button (LED orange or green). Possible causes are deformed
or missing contacts in the connector arm.

17
7.3 IODD file
The IODD file is in the download area of the E-T-A website and can be downloaded there. It is set up according to the regulations
of the IO link user organisation (PROFIBUS User Organisation e.V.).
Various IODDs are available.
A revision has been inserted informing about the previous functional extensions.
ETA-EM12D-TIO-00 I-16-... Extended version, communication with up to 16 channels
ETA-EM12D-TIO-00 I-116-... Standard version, communication with up to 32 channels
This revision index can also be found on the supply module.
If the revision index on the device and the revision index of the loaded IODD are identical, all options of the device can be exploited.
Should the revision index of the supply module be higher than the IODD used, only the options of the IODD will be supported
(downward compatible).
However, no device with a lower revision index than that of the IODD can be used.
Please observe that the IODD used also determines the model of the supply module. The extended version allows communication
with 32 channels. However, this version only cyclically transmits the status of the circuit protectors. The standard version allows
communication with max. 16 channels. Besides transmission of the status, this version also allows cyclical transmission of the
present load current.
7.4 Software versions of EM12D
In the context of functional or portfolio extensions, the firmware used in the supply module is extended or adjusted. Downward
compatibility is ensured with all devices. Old devices do not support new functionalities nor corresponding portfolio extensions
because these are not implemented in the old firmware.

8 Cyclical I/O data
The IODD file defines the data communication between the IO link master and EM12D-TIO intelligent supply module. In detail
these are the status and the load current of the electronic circuit protectors. In addition it is possible to switch the devices on or
off or reset them in the event of a failure.
8.1 Data model for max. 16 channels
8.1.1 Data from IO link master to EM12D-TIO (16 channels)
Each channel of each electronic circuit protector can be switched on or off or reset via the cyclical data. In addition, status information
and measuring values are transmitted.
