The last message displayed may be incomplete if there is active Modbus

traffic while using the MODBUS command.

Modbus RTU only: If the last received message was rejected because of

bad CRC checksum, the MODBUS command displays the message with

corrected CRC (last two bytes updated).

To clear the counters, select again the Modbus mode with the SMODE

command:

>smode modbus

Disabling Modbus

If you stop using Modbus with the transmitter, set the transmitter to some

other operating mode using the display/keypad option or the SMODE

command.

For example, to return the transmitter to the RUN mode where the

measurements are output at regular intervals, issue the following

command through the service port:

>smode run

Alternatively, you can enter the Main Menu using the display/keypad

option, and change the mode from the Interfaces submenu.

The other communication settings of the output interface (User Port,

LAN interface, or WLAN interface) will remain as configured, but the

Modbus protocol will be disabled.
