CS Instruments FA 515 Bedienungsanleitung Seite 16

The FA515 comes standard with a 4...20mA output in 2-wire technique and an RS 485
Modbus output. But it can only be used either the analogue output 4...20 mA or RS 485
Modbus output. Both outputs can not be used at the same time due to the 4...20 mA 2-wire
technology (low power).
Change from 2 wire technolgy to Modbus and back requires the CS Instruments
service software. (Order.No.: 0554 2007)
Before commissioning of the sensor the communication parameters
must be set in order to ensure the communication with the Modbus master.
The adjustment can be done either with the CS Instruments PC service software, DS 400, DS
500 and the hand-held instrument PI 500 done.
Modbus communication default values:
•
Modbus ID : 1
•
Baudrate:
•
Parity:
•
Stoppbit:
Supported are following functioncodes:
•
Function code 03:
•
Function code 16:
