General description
1.4. Communications
All the relays of the ekor.rpa-100 units have two TCP/IP
connection Ethernet ports and a Web server for
configuration. They also have a front mini-USB port for
maintenance and two rear ports with serial communication
RS-485 twisted pair (COM0 and COM1) for remote control.
The standard communication protocols implemented in all
equipment are MODBUS in RTU transmission mode (binary)
and PROCOME, through the rear RS-485 COM0 port fitted in
these units.
Optionally, the ekor.rpa-120 model also has a bus for
temperature sensor connection.
The ekor.rpa-100 relays can be interconnected to other
units in the ekor.sys family, as shown in the image below.
