
In buffer memory locations (BFM’s) marked with an “*” data can be written from the PC using
the TO command.

For buffer memories (BFM’s) without “*”mark, data can be read to the PC using the FROM
command.

Before reading from the analog special function block, ensure these settings have been sent to
the analog special function block. Otherwise, the previous values held in the analog block will
be used.

Offset (intercept): The analog input value when the digital output becomes 0.

Gain (slope): The analog input value when the digital output b1000.
Note
1) Channel Selection
Channel initialization is made by a 4 character HEX number HOOOO in buffer memory BFM #0.
The least significant character controls channel 1 and the 4 character controls channel4.
