Part 3 Controller Data Structure
INTELLIGENT ACTUATOR
z The variables and flags in the global range will be retained even after the controller power is turned off.

z The variables and flags in the local range will be cleared when the program is started.
z Ranges of values that can be used in SEL language
,QWHJHUVDQGUHDOQXPEHUVFDQEHXVHG+RZHYHU pay due attention to the following limitations:
1XPHULFGDWD
The X-SEL Controller can handle values of maximum eight digits including a sign and a decimal point.
Integer: -9,999,999 to 99,999,999
Real number: Maximum eight digits including a sign and decimal point, regardless of the size of value
([DPSOH
If a floating point is used in operations, the number of valid digits will be limited to seven. Also note
that operations using a floating point are subject to error.
3RVLWLRQGDWD
The input range of position data consists of four integer digits and three decimal digits.

the precision of the last digit may decrease.
Consider the above limitations fully when using values. Particularly when the CPEQ command is used
in a comparison operation using real numbers, a match will rarely result. In this case, the CPLE or
CPGE command that looks at the magnitude relationship of two terms must be used.
