OPERATION CONTROL PROGRAMS

4.1
Operation Control Programs
Operation control programs
• Substitution operation expressions, motion-dedicated functions and bit device control commands can be set in operation
control program.
• Multiple blocks in one operation control program can be set.
• There are no restrictions on the number of blocks that may be set in one operation control program. However, one program
is within 128k bytes.
• The maximum number of characters in one block is 1020.
• Transition conditions cannot be set. Transition conditions can be set only in transition programs.
• The bit conditional expression that logical data value (true or false) is returned in an operation control program, a
comparison conditional expression can be set up only as a source (S) of device set (SET=) or device reset (RST=).
An operation control program example is shown below.
#0=D0+(D1+D2)*#5//Substitution expression (four arithmetic operations)
W0:F=SIN(#10F)//Substitution expression (standard function)
CHGV(K2,K10)//Motion-dedicated function
SET M100=M0+X0//Bit device control (SET=)
RST M10=!X0//Bit device control (RST=)
DIN D0,X0//Bit device control (DIN)
