• When communications function is used
When HART communication is used, a mark is displayed in the upper field on the display.
When PROFIBUS communication is used, if the communication is made between the PROFIBUS
option board and the converter main board, a mark is displayed in the upper field on the display in the
same way as in HART communication, while communication between the PROFIBUS option board
and the external bus, nothing is displayed.
