7 - Ekip Com Modbus RTU modules
Description
Ekip Com Modbus RTU is a communication accessory module that integrates the circuit-breaker in an
industrial remote supervision and control network.
It can be connected to a RS-485 network with a Modbus RTU communication protocol, and allows you to:
• Connect the trip units to the network, with dialog functionality.
• Command opening and closing of the circuit-breaker from remote.
• Provide information on the state of the circuit-breaker (open, closed, tripped).
• If mounted on a circuit-breaker in withdrawable version, detect the connected/disconnected position.
For more details about how to access information and transmit commands to the trip unit via the module,
consult chapter "System Interface" on page 155.
Remote opening and closing of the circuit-breaker can be performed only if the circuit-breaker is equipped
with an Ekip Com Actuator module (see page 243).
For applications in which a high network reliability is necessary, the module can be installed along with the
corresponding Redundant module.
The Redundant module is identical in terms of characteristics and installation, but its wiring is different from
the non-Redundant model.
IMPORTANT: on each circuit-breaker, only one Ekip Com Modbus RTU, and only one
Ekip Com Modbus RTU Redundant can be installed.
IMPORTANT: functionality is guaranteed with the circuit-breaker in the Racked-in
and Test positions. When the circuit-breaker is in the Withdrawn position, the only
valid information transmitted is:
• Connection of trip unit to Com module (Trip unit disconnected = disconnected).
• CB position (CB isolated / CB connected = CB isolated).
• Presence of com module ( = present; only valid for the module to which it is connected).
Further details are given in document 1SDH001140r0001 (Communication System
Interface for Emax 2), sections Status Global 1 [dlog], Status Accessories 1 and
Status Accessories 2.
The modules are always supplied with Ekip AUP and Ekip RTC contacts (see the chapter "16 - Other
accessories" on page 244).
Compatibility and power supply
The modules can be installed combined with Ekip Touch, Hi-Touch, G Touch, and G Hi-Touch trip units, and
require the presence of an Ekip Supply module in the first slot of the circuit-breaker terminal box.
Signallings
B
A
The following table shows the possible signals, and their meaning:
Pos. Description
A
Power LED, green. The possible states are:
• Off: power supply absent.
• On fixed: power supply and communication with the trip unit present (with a trip unit with the
Alive LED option disabled).
• On, with one flash per second (synchronized with that of the green LED on the trip unit):
power supply and communication with trip unit present (with a trip unit with the Alive LED
option enabled).
• On, with two quick flashes per second (not synchronized with those of the green LED on the
trip unit): power supply present, and communication with trip unit absent (for example: because
of Local Bus disabled).
B
RX and TX LEDs, green. The possible states are:
• Off: Modbus RTU communication not active.
• On, flashing rapidly: Modbus RTU communication active.
