Summary of the Analog Input Slave Units
Section 6-2
The flow of data calculation is as shown in the flow chart below.
Selection of Allocation
Data After performing each calculation, 6 types of data "Raw Value", "Peak Value",
"Bottom Value", "Top Value", "Valley Value", and "Rate of Change" can be
selected for allocation to I/O. The selected data becomes "Analog Data 1" and
can be allocated independently or with a status flag to the Master Unit. The
selection process is performed by either CX-Integrator or Explicit message. In
addition, comparison calculation of "Analog Data 1" with 4 types of alarm set-
tings (Alarm Trip Point High (HH), Warning Trip Point High (H), Warning Trip
Point Low (L), Alarm Trip Point Low (LL)) can be performed. (Comparator
