This is an examinable program that takes the difference of the AD368 input with the

previous input,magnifies it (x2), and outputs from DA374. The 4 to 20 mA mode is

assumed for AD368.

Code a routine to "set the disconnect error flag and set the input to 0 when

disconnect is detected" prior to the above routine because the 4 to 20 mA mode of

the AD368 has a disconnect detection function.

In this example, Declared 'OPEN-ERR' as global variables,Addition to I/O Variable

Also, declare the previous value as a static variable because it must be retained

internally.
