Note: When changing reporting modes from binary to BCD or from BCD to binary
The peak hold function can be used to detect peak conversion values of rap-
idly changing analog input signals. These values are stored in separate
memory locations in the module memory map. This data is reset each time
the peak hold function is enabled for the input point. The Peak Hold Reset
Bits and Acknowledge flags, which are available in the I/O Words, are de-
scribed in Section 5.
To apply the peak hold function for each input point, set the input point peak
hold enable bit for each input point.
with peak hold enabled, the peak hold data may be invalid until the peak hold
function is re-enabled.
The alarm function can be used to perform a comparison of the input point
conversion data to specific low and high limits that are stored in the module
memory map. The module sets the alarm bits in the module memory map
when the input point conversion data is outside the specified limits. The mod-
ule can perform low alarming, high alarming, or both.
To use this function for each input point proceed as follows:

Set the input point low alarm limit value and input point high alarm limit
value for each input point.
Set the input point low alarm enable bit and input point high alarm en-
