Connection of the RS-485 serial interface
Modbus connection protocol (RTU):
- Baudrate: 9600
-
-
- Frame Settings: E 8.1
- Address: 1
- Timeout: 1000
(*) Closing current, ground 0.5 mA (SELV: ultra low safety voltage)
SIGNAL CABLE (<24V): BUS-SCS cable consisting of 2 flexible conductors, with a cross-section of 0.50 mm
DATA TRANSMISSION CABLE (RS-485): 1 X 2 X AWG 24 FLEX S(FTP) LSZH RS485 MODBUS serial bus cables for Canbus and Modbus applications. Belden type 14S7KVZ or equivalent.
The shield must be grounded at one end of the cable only.
CONTROL CABLE (230 V):
Electric cable with section 1.5 mm
ATTENTION:
The system must be built in compliance with the relative project and in compliance with the regulations in force in the place of installation.
It is absolutely forbidden to pass signal and data transmission cables together with power cables with voltages> 50 V.
