9.1 RS-485 simple mode configuration
This protocol allows the instrument to output data to an external device (PLC, SCADA, PC,
etc.). The communication is unidirectional. The data are output on the RS-485 link as simple
ASCII text. If for instance you use a PC, the data can be easily visualized and saved in a file
using the "Hyperterminal" software.
To use this communications mode, on the instrument:
Select the menu "Communication/RS-485" and choose the protocol "Simple" (default
•
configuration).
Select the menu "Communication/RS-485 Simple/Configuration".
•
Note: In case of problem verify first that jumper J3 is not installed on the mother board (default
configuration).
Send data
The button "Stop Cyclic meas." allows to stop and to restart the cyclic transmission of
measurements. It is advised to stop the cyclic transmission in order not to mix cyclic
measurements and data of the file being transmitted. This button has the same effect as the
"Enable" checkbox of the "Communication/RS-485 Simple/Configuration" window.
After stopping the cyclic measurements, select the "Calibration Reports", "User Actions",
"Configuration", "Measurements" button to send the corresponding file, or the "All files" button
to send all these files in one shot.
Once the button is pressed, the file is sent immediately. The field "Current file status" shows
"Sending" alongside the file transmission progress bar. On completion this changes to "Sent".
