FX Series Programmable Controllers
Modifying a Constant
Constants can be modified just as easily as data registers or bit devices. If, for example, the
constant K20 was actually written K20V the final result would equal:
K20 + the contents of V
Example:
Misuse of the Modifiers
Modifying Kn devices when Kn forms part of a device description such as KnY is not possible,
i.e. while the following use of modifiers is permitted;
Statements of the form:
are not acceptable.
Using Multiple Index Registers
T h e u s e o f m u lt i p l e in d e x r e g i s t e r s i s
sometimes necessary in larger programs or
programs which handle large quantities of
data. There is no problem from the PLC’s
point of view in using both V and Z registers
many times through out a program. The point
t o b e a w a r e o f i s t h a t i t i s s o m e t i m e s
confusing for the user or a maintenance
person reading such programs, as it is not
always clear what the current value of V or Z
is.
Example:
V = 10 (K10)
Z = 20 (K20)
D5V = D15 (D5 + V = D5 + 10 = D15)
D15Z = D35 (D15 + Z = D15 + 20 = D35)
D40Z = D60 (D40 + Z = D40 + 20 = D60)
Both V and Z registers are initially set to K10 and K20 respectively.
The contents of D15 is added to that of D35 and store in D60.
V is then reset to 0 (zero) and both V and Z are used in the double word addition (DADD).
The contents of D1, D0 are then added to D3, D2 and then finally stored in D25, D24.
If V = 3276 then K20V
• Modifiers cannot be used for parameters entered into any of the 20 basic instructions,
i.e. LD, AND, OR etc.
