3 General description
Requirements in plant engineering and construction and in building automation are growing and growing. In
the context of increasing efficiency and reducing costs, the transparency of systems, remote maintenance
and remote access are getting more and more important. 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 EM12D interface module. The system combines the
well-proven quality of DC24V overcurrent protection with the communication capabilities to superordinate
bus systems. 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 individual circuit protector. In addition, the present load
current of the circuit breaker and the load voltage are transmitted to the superordinate control unit. A
parameterisable limit value allows creation of a warning threshold which advises the user of changing system
conditions.
The new generation of electronic overcurrent protection REX12D consists of the EM12D-TMB intelligent
supply module and the REX12D versions of electronic circuit protectors which can be mounted side by side
in optional numbers. The 12.5 mm wide modules feature push-in technology for wiring 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 various needs of the users. And what is more: no additional accessories are
required when connecting the individual components electrically and mechanically. This helps save time and
money!

fig. 1: System overview
The Modbus controller EM12D-TMB is the centre of the ControlPlex® system. It collects all information of
the REX12D electronic circuit protectors and forwards it to the superordinate Modbus server and thus to the
superordinate control unit.
The Modbus interface to the superimposed control unit is realised with a 3-wire cable. It allows connection
®
of the ControlPlex
system to the Modbus server, thus enabling display and analysis of the individual
measuring values as well as diagnosis and control of the individual electronic circuit protectors. The user has
unrestricted access to the safety-relevant functions in the event of a system disruption. 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.

fig. 4: Mounting position
4.2 Power supply of the Modbus RTU controller
Power supply of the Modbus controller is via the line entry terminals LINE+ and 0V.
4.3 Terminals for the voltage supply and the ELBus
®
The operating voltage of the device is 24V DC. Faultless operation of the device is ensured in a voltage range
of 18V to 30V. The max. current of the supply module is 40A.
Using a supply voltage outside the indicated operating range can cause malfunctions or destruction of
the device.
4.3.1 Connector sockets for the Modbus RTU communication, connector socket X81/ X82
These connector sockets serve for connection of the Modbus controller EM12D-TMB with the superordinate
control unit. This connection is a one-to-one wiring.
1. communication A
2. communication B
3. communication GND
fig. 5: Modbus RTU connection
Preferably, the connection should be effected with a three-pole shielded cable. The cable length between the
Modbus controller EM12D-TMB and the Modbus server has to comply with the benchmarks.

5 Operating modes of the Device EM12D-TMB
5.1 Operating mode: (system start)
The Modbus controller is initialised by applying the supply voltage. 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 Modbus controller 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 Modbus controller 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 no valid or invalid configuration data available in the Modbus controller, it will change into this
operating mode. This operating mode will be left upon receipt of the correct module and slot parameters and
configuration data. The circuit protectors remain OFF.
9
Page 10
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”. The circuit protectors will adopt
the condition specified by the configuration. If there is a connection between the Modbus controller and
the superordinate control unit and there is no critical failure, the operating mode “independent operation”
will be quitted. Should the connection between the Modbus controller and the superordinate control unit
be interrupted during operation, the Modbus controller will automatically change into the operating mode
“independent operation”.
Should the connection between the Modbus controller and the superordinate control unit 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 Modbus controller and the superordinate control unit 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”.
By means of the non-cyclical parameter, the behaviour of the Modbus controller can be defined in the event
of an interruption of the communication to the superordinate control unit.
Either the condition of the circuit protector is frozen (FREEZE) or all circuit protectors are switched off
(UNFREEZE).
Should the connection between the Modbus controller and the superordinate control unit be restored after a
previous interruption, the operating mode “independent operation” will be quitted.
5.5 Operating mode: (Faultless operation)
If there is neither a critical nor a non-critical failure and if there is a connection to the superordinate control
unit, the Modbus controller will change into the operating mode “faultless operation”. The parameters will be
transmitted from the superordinate control unit to the Modbus controller and will be saved there. Subsequently they will be forwarded to the electronic circuit protectors. The slot configuration data and slot parameters
will be exchanged over Modbus Register between the superordinate control unit and the Modbus controller.
5.6 Operating mode: (bootloader)
®
ControlPlex
Views tool allows putting the Modbus Controller into the bootloader mode and to load a new
firmware. The actual procedure is described in a separate document.

6 Basic functions of the entire system
6.1 Internal cycle times
®
The cycle time via the ELBus
is 530ms. During the aforementioned period the status and the load current of
each circuit protector is cyclically transmitted to Controller EM12D-TMB.
fig. 9: Cycle times of the system
6.2 Hot swap of circuit protectors
The electronic circuit protector REX12D 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 intermittently be marked as
unvalid.

7.1.1 Error with faulty population
If a double channel device is connected as channel 16/17, the control unit will receive the information that a
device is available at channel 16.
When reading out the Cominfo of the circuit protector, received the message that the circuit protector has wrong
parameters.
The channels cannot be operated (cannot be switched on).
7.1.2 Error device addressing
Due to mechanical problems, there may be addressing errors.
The LED on EM12D is permanently lighted orange.
Possible causes are deformed or missing contacts in the connector arm.
For putting the device into service again, the faulty circuit protector has to be removed and the supply voltage
has to be switched off and on again.
7.2 Physical interface
The physical interface used is RS485. Protocol used is the Modbus RTU protocol. It is unsusceptible to EMC
disturbances and allows artless implementation of the bus communication.
7.3 Setting the communication parameters
The parameters for the communication to the Modbus server are realised by means of the switches on the
device side.

fig. 24: Configuration data of the EM12D intelligent supply module
Behaviour in the event of communication disruption:
Bit 1 unfreeze = 0 all load outputs (channels) of the circuit protectors are switched off and the
EM12D-TMB changes into the operating mode “independent operation”.
Bit 2 freeze = 1 all load outputs (channels) of the circuit protectors remain in their current
condition and the EM12D-TMB changes into the operating mode “Independent operation”.
Bit 2 power saving mode deactivated = 0 LEDs always have full illuminating power
power saving mode activated = 1 LEDs have reduced illuminating power in the
OK condition
