14 - Ekip Link module
Description
Ekip Link is a communication accessory module that integrates the circuit-breaker in an internal Ethernet
network with an ABB proprietary protocol.
The network to which the module is to be connected must be dedicated and comprising only Ekip Link and
Ethernet switches that declare support for level L2 multicast on the datasheet. In this case the Ethernet
switches do not require any configuration. If, instead, the network also includes routers, multicast must be
enabled and configured on all L3 Layer VLAN interfaces.
IMPORTANT: the module can be connected only to Ethernet networks inside one or
more switchboards, to which trip units or ABB Emax 2 accessories are connected.
It is the installer's responsibility to ensure that all the necessary security measures
are adopted for all the connected devices (for example, the necessary access
authorizations, and so on). The module cannot be connected to other Ethernet
networks (for example, with the purpose of monitoring the system, or the office), or
to the Internet.
The module is necessary if you wish to implement the following functions:
• Power Controller
• Zone Selectivity
• Programmable Logic
For these functions, the trip units of the system that are involved must be equipped with an Ekip Link, and for
each of them the IP addresses of the Ekip Link modules of the other trip units must be inserted.
The Ekip Link modules must be connected to a dedicated network that includes only Ekip Link modules and
Ethernet switches that declare support for level L2 multicast in their data sheets. In this case, the Ethernet
switches do not require any configuration. If instead the network also includes routers, multicast must be
enabled and configured on all L3 Layer VLAN interfaces.
For each Ekip Link, every other trip unit connected to the network is considered as an actor. In addition, each
Ekip Link can be interfaced with a maximum of 15 actors, of which a maximum of 12 for the Zone Selectivity
function.
With the Power Controller function, every trip unit can:
• Acquire the state of the loads from remote and monitor them.
• Play the role of Master, and collect the energy measurements of the trip units selected as Energy Meter.
• Supply energy measurements to the trip units inserted as master.
The state of the loads can be acquired by checking the state of the inputs of the signalling modules connected
to the trip units whose IP address has been entered, while the loads can be monitored by programming their
outputs.
Remote acquisition of the state of the loads and monitoring of the loads can also be implemented with Ekip
Signalling 10K modules connected to the network.
For further information about the Power Controller function see the chapter "23 - Ekip Power Controller" on
page 131, and "2 - Load control" on page 159.
With the Zone Selectivity function:
• The IP addresses inserted refer to the trip units with the role of interlock.
• For every interlock trip unit inserted, the protections for which selectivity is to be implemented must
be selected by setting a mask. The function set in this way is indicated hereafter as logical, in order to
distinguish it from the standard function, hereafter referred to as hardware.
• The protections selected in this manner are added to the hardware protections S G D-Backward and
D-Forward.
• It is possible to choose between hardware-only selectivity and both hardware and logical selectivity.
• It is possible to set diagnostics to check for each interlock trip unit whether there is consistency between
the hardware and logical selectivity information.
• It is possible to set a mask that identifies the protections from which the received information about
selectivity is to be retransmitted, regardless of whether the trip unit is in alarm conditions. The information
to which the mask is applicable regards only logical selectivity.
