Position Data
Section 4-4
4-4-1 Position Data Address
Specify position data at the following addresses in MC Unit memory. Specify
the addresses in hexadecimal when using IOWR/IORD instructions.
In MC Unit programming, the position data address is specified as a type of
variable as shown below:
PL<Address No.>: Specify 0000 to 27FF as the address No.
(Example)
MOVE_[J1]#PL01FF
4-4-2 Position Data Configuration
Each position data is comprised of two words (4 bytes). Though the position
data of the MC Unit does not have a decimal point decimal, however, a deci-
mal point is added to the data based on the setting of Position command dec-
imal point position (P5AA02) in Axis-machine parameters.
Data Range
−
2147483648 to +2147483647 (80000000 Hex to 7FFFFFFF Hex)
Example 1: Position data 12345 (00003039 Hex)
When Units (P5AA01) of Axis-machine parameters is 0: mm and Position
command decimal point position (P5AA02) is 3: 0.001, the position data
12345 is handled as 12.345 mm.
Example 2: Position data
−
12345 (FFFFCFC7 Hex)
When Units (P5AA01) of Axis-machine parameters is 1: inch and Position
command decimal point position (P5AA02) is 2: 0.01, the position data -12345
is handled as
−
123.45 inch.
4-4-3 Indirect Specification
Indirect specification can be used only for position data.
1,2,3... 1. Add the symbol @ in front of position data, indicating to use the position
data specified by the stored data (address).
• As shown below, @PL0001 specifies the stored data 0012 of the position
data PL0100.
