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.
