Outputting Scan Count and Numerical Calculation
Scan Count and Results of Numerical Calculations can be output to “OUT0-15” (or “OUT0-7”) of the I/O
connector dividing in multiple times.
•
Numerical Calculations can be set to output or not for each expression. Only the expression that is set
to “Output” is output.
•
The numerical calculation results that are output are integers only. A number with a decimal point is
rounded off to the nearest whole number.
•
The output order is Scan Count -> Judgement -> Numerical Calculation.
•
When outputting a numerical calculation result while you inspect in "Automatic Switch" mode, PV
outputs the result of only the block executed lastly.
About output timing of signals, refer to Chapter 8.3.2 Outputting All Results (Output = All), page 384.
1.
Select “Parallel I/O Output” in
“Input/Output” setting window.
2.
Select “All Selectable” for “Output
Data”.
3.
To output Scan Count and Numerical
Calculation, select “Output” for them.
4.
Set "Bit Width".
Select it depending on the value of output data.
[8-bit]: Outputs to “OUT0-7” by 8-bit.
When “Data Bit” is 32-bit, it outputs by 8-bit in four divided data from lower bit.
[16-bit](default): Outputs to “OUT0-15” by 16-bit.
When “Data Bit” is 32-bit, it outputs by 16-bit in two divided data from lower bit.
Refer to the next section for output example.
5.
Set “Data Bit”.
Select it depending on the maximum value of output data.
Value that can be output
[8bit]:
0 to 255
[16bit]:(default) 0 to 65535
[32bit]: -2147483648 to 2147483647
*Negative values are output in the complement number of 2.
Setting of “8-bit” and “16-bit”:
• Negative values cannot be output. If the values are negative, the result is output as “0”.
• The data exceeding the output range (8-bit or 16-bit) will be output as value of “0”.
6.
Set "Handshake” and “Output Signal Guarantee Time (ms)”.
When you employ handshake, specify “Timeout (ms)”.
See the section of "Outputting All Judgement (JDC) That Have Been Set”, page 271.
