10 - Ekip Com Modbus TCP modules

Description Ekip Com Modbus TCP is an accessory module that can function as a communication module integrating the
220 | © 2017 ABB | 1SDH001330R0002 - ECN000058721 Rev. A
circuit-breaker in an industrial remote supervision and control network or as an HTTP Server.
As communication module, it can be connected to an Ethernet network with Modbus TCP communication,
and allows 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).
As HTTP Server, connected to an Ethernet network, this module allows read-only access to the information
of the trip unit. This access is possible through a browser, inserting the IP address of the module. Once the
trip unit has been found, a login page is opened that asks for the user password to be inserted, which is the
same password to be inserted in the display to modify the parameters.
IMPORTANT: since the module allows control of the circuit-breaker and access to
the data contained in the trip unit, it can only be connected to networks that meet
all the necessary requirements for security and prevention of unauthorized access
(for example, the network of the control system of an installation). It is the installer's
responsibility to ensure that all the necessary security measures are adopted (for
example, firewalls, and so on). The module cannot be connected directly to the
Internet. Connection to dedicated Ethernet networks through the Modbus TCP
communication protocol is recommended.
The following table shows the ports used by the module:
Port Service
502/tcp Modbus TCP
80/tcp Server HTTP
319/udp
IEEE 1588
320/udp
68/udp DHCP client
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 TCP, and only one
Ekip Com Modbus TCP Redundant can be installed.
IMPORTANT: when the circuit-breaker is in the disconnected position, the trip unit
is disconnected from the module: in this condition, 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).
Notes
When the module is used as Modbus TCP/IP communication module.
When the module is used as Server HTTP.
When IEEE protocol 1588 is enabled (see paragraph "Configuration", on
page 224).
DHCP Client enabled as an alternative to "Static Address = On"
