Overview of Analog I/O Slave Units Section 6-1
Analog processing is performed according to the following flowchart.
6-1-4 Selecting Data for Analog Input Slave Units
After performing math operations, select one out of the six resulting values to
allocate in the Master Unit, from the analog input value, peak value, bottom
value, top value, valley value, and rate of change. The selected data is
referred to as “analog data” and can be allocated in the Master Unit individu-
ally or in combination with Status Flags. The data is selected using the CX-
Integrator. For Analog Data, comparator operations with four alarm set values
can be performed (comparator function).
