Overview of Analog I/O Slave Units Section 6-1
CRT2-DA02 Analog Output Slave Units
6-1-3 Data Processing Flowcharts for Analog Input Slave Units
Analog Input Value The following math operations can be performed on the external analog input
value. The values obtained after processing (analog input values) can be allo-
cated as I/O in the Master Unit.
• Scaling to desired industry unit
• Moving average processing
Other Operation Results After moving average processing and scaling, the analog input value can be
processed using the following operations. The values after processing are
called peak value, bottom value, top value, valley value, rate of change, and
cumulated value.
• Peak/hold operation
• Top/valley operation
• Rate of change operation
• Cumulative operation (maintenance function)
Function Details
Scaling Performs scaling.
Scaling allows conversion of values between 0 and 6,000
into values using the industry unit required by the user. It
reduces the number of operations required in ladder pro-
gramming in the Master Unit.
User adjustment Adjusts the output when an offset occurs in the output volt-
age or current.
Cumulative counter
(maintenance function) Calculates an approximation to the integral of analog out-
put values over time.
Communications error
output setting Sets the value output when a communications error occurs
for each output.
