COMMUNICATION AND HMI
14.1 Local communication port. USB
An USB port is featured on the front of the device. The connector used is USB connector. The protocol
used is Modbus RTU (115200
–
8 bit
–
no parity
–
1 bit stop).
The ground from the PC should be connected to the same ground as the relay in order to prevent
communication problems.
The USB communication system is insulated from the auxiliary voltage, but not from the shared voltage
of the relay processors, so the cable connecting the PC to the relay should not be excessively long in
order to avoid potential electromagnetic interference with the device.
14.2 Remote communications ports.
14.3 LCD and keypad
The front of the SIL-G relay is fitted with an alphanumeric LCD screen, measuring 20x4. This screen
provides the user with access to read information about the settings parameters, measurements, status
and events. All of this information is arranged in a system of menus.
A keypad is fitted to the relay front panel, which can be used to access the information shown on the
LCD screen and to navigate through the menu system.
This membrane keyboard has 6 keys that can be used to navigate through the different menus and to
change the setting parameters. The ▲ ▼ and ◄ ► keys can be used to navigate through the different
menus, the different options in each menu and the different values for the settings parameters.
The “
OK
” key is used to access the menus and the different options, as well as to approve changes to
values. The “
