Guía de integración 4-20mA y RS485 Modbus

Categoría：Integración

Alimentación, escala analógica, bus RS485 y parámetros de comunicación.

Analog output

Confirm the instrument output range, PLC/DCS input type, loop supply and load. Match engineering-unit limits to the 4-20mA scaling.

RS485 Modbus

Align address, baud rate, data bits, parity and register map. Use a suitable bus topology and configure shielding, grounding and termination for the site.

Commissioning records

Verify real-time value, temperature, status word, alarms and fault codes separately, and record instrument value, host value and timestamp.
