CN8240/CN8260 Parameter Codes

“X”s mark parameters that are supported by the CN8240 and CN8260 and “O”s indicate parameters that are not supported.

This field contains the ASCII representation of an 8-bit value

in which the bit assignments are as follows (starting from the least significant bit):

X	Process Input Error
X	RAS Error
0	Always Zero
X	Loop Break
X	Alarm 1 Active
X	Alarm 2 Active
0	Always Zero
0	Always Zero

If a bit at a location marked as “X” is set, then the condition is TRUE.

For example, a “48.000” in the data field means that both alarm 1 and alarm 2 are active and everything else is FALSE.
