Whenever a PLC-5/x6 processor detects conditions worthy of a
prompt, it sets corresponding bits in Bit File 169 in the data table.
We list conditions for which the software is designed to detect and
signal a prompt.
We recommend that you program a method to display bit numbers of
detected prompt conditions. Then, you can respond quickly by
looking them up in the following table.
