B CRT Editor
With the Modbus firmware version 1.20 and higher, the Modbus server is equipped with the CRT function (CRT: Customer
Register Table). With this function, it is possible to use user-defined register addresses which have previously been se-
lected and created.
The CRT editor is used for creating the user-defined register addresses.
• Start the CRT editor by double clicking the file CRT_Editor.exe.
The start window is opened (see Fig. B.1).
B.1 Connection of the Serial Interface RS485
• Connect the RS485 interface of the transmitter to the PC via a RS485 cable. If the RS485 cable cannot be connected to
the PC, use a RS485/USB adapter.
For the connection of the RS485 interface to the transmitter see user manual FLUXUS or PIOX.
• Switch on the transmitter.
• In the start window, click the button Communication (see Fig. B.1).
• Check the transmission parameters (see Fig. B.2). They have to be identical with the transmission parameters set in the
transmitter (see section 2.3).
