I/O Control Operation
The following FBs perform I/O processing including analog input/output, pulse integration, and batch counter.
■Analog Input Processing
Function block symbol
Processing details
M+P_IN
Performs range check, input limiter, engineering value inverse conversion, and digital filter
processing.
The input limiter processing can be enabled or disabled on the "Options" window of the
engineering tool.
■Output Processing-1 with Mode Switching (With Input Addition)
Function block symbol
Processing details
M+P_OUT1
Performs input addition, variation rate & high/low limiter, reset windup, and output conversion
processing to an input value (MV) and outputs a manipulated value. (with integral and anti-reset
windup processing)
■Output Processing-2 with Mode Switching (Without Input Addition)
Function block symbol
Processing details
M+P_OUT2
Performs variation rate & high/low limiter processing and output conversion processing to an input
value (MV), and outputs a manipulated value. (without integral and anti-reset windup processing)
■Output Processing-3 with Mode Switching
Function block symbol
Processing details
M+P_OUT3_
Performs input addition, MV compensation, preset MV, MV hold, MV tracking, variation rate & high/
low limiter, reset windup, tight shut/full open, MV reverse, and output conversion processing to an
input value (MV) and outputs a manipulated value.
■Manual Output
Function block symbol
Processing details
M+P_MOUT
Reads a manipulated value (MV) of tag data, performs output conversion processing, and outputs
a manipulated value.
■Time Proportioning Output
Function block symbol
Processing details
M+P_DUTY
Performs input addition, variation rate & high/low limiter, reset windup, output ON time conversion,
and output conversion processing to an input value (MV) and outputs the value as bits.
■Pulse Integrator
Function block symbol
Processing details
M+P_PSUM
When the integration start signal (RUN) is TRUE, this function block performs input value
increment operation, integrated value calculation, and output conversion processing to a count
value (CIN) and outputs the result.
■Batch Counter
Function block symbol
Processing details
M+P_BC
Compares the input (CIN) with the estimated value 1 and estimated value 2, and outputs a
completion signal when the input reaches an estimated value.
At this time, this function block performs the high limit check, variation rate check, and output
conversion processing to the input (CIN).
■Manual Setter
Function block symbol
Processing details
M+P_MSET_
Performs SV variation rate & high/low limiter processing, sets the result as the set value (current)
(SVC) of tag data, and outputs the value (SVC).
