Omron FH-3 Series Reference Manual page 629

Set expressions in the following manner.
• Calculation 0: DIST (U1.SX, U1.SY, U2.SX, U2.SY)
This expression is used to calculate the distance between the reference positions of unit 1 and unit 2.
The function "DIST" calculates the distance between 2 points.
• Calculation 1: DIST (U1.X,U1.Y,U2.X,U2.Y)
This expression is used to calculate the distance between the measurement positions of unit 1 and unit 2.
The function "DIST" calculates the distance between 2 points.
• Calculation 2: U3.D01-U3.D00
(Unit 3: Calculation [Calculation 1] - Unit 3: Calculation [Calculation 0])
This equation is used to calculate the difference between results of Calculation 1 and Calculation 0 in unit
3 (in this example, Operation).
Note
Calculating order of expressions
• Express that use the express results of other expressions must be set with an expression number that is higher than that
of the substituted expression. If it is set with a number smaller than the number of the substituted expression, previous
expression results of the substituted expression will be inserted.

Calculation 7
Calculate the distance between the two points in the inspection region in
Operation Formula 0: [DIST (U1.X, U1.Y, U2.X, U2.Y)]
Operation Formula 1: [U3.DO0+120.25
When you substitute these equations with each other
Operation Formula 0: [U3.DO0+120.25
Operation Formula 1: [DIST (U1.X, U1.Y, U2.X, U2.Y)]
Counting Number of Measurements
The measurement count is counted by adding "1" to each calculation number 0.
Note
• When expression results are cleared or the power is turned off, U3.D00 will return to "0" and the measurement counts
will also be reset.

Since the calculation of operation
formula 0 is earlier than operation
