2 - Ekip Com Modbus RTU

Ekip Com Modbus RTU is a communication accessory which allows Ekip Touch to be integrated into an RS-
485 network with Modbus RTU communication protocol, remote supervision and monitoring functions, in two
different modes, master and slave.
You can perform the following operations remotely:
• read Ekip Touch measurements and information
• manage certain controls, including opening and closing the actuator
• access information and parameters not available on the display
• If connected to a withdrawable version of the circuit-breaker, the allows the racked-in/racked-out status
to be detected
NOTE: the remote open and close commands of the circuit-breaker can only be executed if
Ekip Touch is in the Remote configuration and the circuit-breaker is equipped with the
Ekip Com Actuator module (page 234)
Ekip Com Modbus RTU is always supplied with contacts Ekip AUP and Ekip RTC (page 234.
The System Interface document is available for mapping the module in its communication network. All the
required communication and command details are listed in the document (page 182).

Models Two different modules compatible with the Modbus RTU protocol are available: Ekip Com Modbus RTU and
Ekip Com Modbus RTU Redundant.
The modules are identical in terms of characteristics and installation methods, except for: display menus,
cabling and addresses for system communication, which are specific for each module.
NOTE: if different indications are not given, the information in the next chapter is valid for
both models
The two modules can be connected at the same time to Ekip Touch so as to expand the potential of the unit
(e.g. for applications where high grid reliability is required).
IMPORTANT: each Ekip Touch can be fitted with only one module per type. The
configuration with two modules of the same model is not allowed (example: two
Ekip Com Modbus RTU Redundant)

Connections The module must be assembled in the first vacant slot of the terminal box after Ekip Supply, either on the
circuit-breaker (fixed version) or on the fixed part (withdrawable version).
To connect the module to its communication network and for references about the terminals, please consult
document 1SDM000091r0001; use Belden 3105A type cables or equivalent for the external cabling.
To connect the module to Ekip Touch, please consult document 1SDH001000r0512.

Power supply Ekip Com Modbus RTU is supplied directly by the Ekip Supply module to which it is connected.
NOTE: communication between Ekip Touch and the module is interrupted in the absence of
auxiliary power supply
