EQP LOGIC EDITOR
In the example to the below, an Input Variable was placed and linked to a global memory point “MCOP-FA001”.
The value for this point was generated on the preceding
sheet where it was assigned to the global database.
Once placed in the global database, the value of
“MCOP-FA001” can be used as an “Input Variable” on
any other sheet in the project.
Data Types
Functions and Function blocks typically require a specific data type to be
attached to their input and output pins. The S 3 online help file provides
detailed information on both the data type compatibility requirements as
well as how each logic operator functions. Below is a definition of the
available data types, within the S 3 database these types are represented
as follows:
B = Boolean
I = Integer
D = Double
F = Float
S = String
T = Time/Date
Detector IEC 1131-3 Range
Boolean Boolean 8 bit value, 1 = True, 0 = False
Integer Integer 2 bytes, 16 bit value, -32,768..32,767
Double Double Integer 4 bytes, 32 bit value,2,147,483,648..2,147,483,647
Float
Real 4 bytes, 32 bit value (IEEE 754 single precision)
Most positive number 3.4028E+38
Least positive number 1.1754E-38
Least negative number -1.1754E-38
Most negative number -3.4028E+38
Note
When floats are used in a comparison for equal (=), the comparison will be true if the values are within 0.01 of
each other.
String String 80 bytes (Not supported as an I/O variable)
Time/Date Undefined Item ID Description Data Type
1 Seconds (0-59) Integer
2 Minutes (0-59) Integer
3 Hours (0-23) Integer
4 Day (1-31) Integer
5 Month (1-12) Integer
6 Year Integer
When displayed as a string the format is mm/dd/yyyy hh:mm:ss
Structure Structure A structure that does not have a fixed length.
