Position Data Configuration

The variables of the same address share the same physical space even
though the types are different. Therefore, the memory image after execution
of (1) and (2) will be as described in the table below. If the same address is
accessed using a different access type, a different value will be read. So it
needs special attention.
Case Original value
(1) 1234
(2) 1.234000E+003 449A4000hex
If the bit type is selected for data access, the bit position in 16-bit word data
needs to be specified with "Bit No.".
Example) "MB10002" indicates the second bit of MW1000.

There are 10240 of position data that can be used. In a motion program, posi-
tioning is executed by specifying a position directly or by specifying a position
in the position data (indirect specification). Position data is transferred
between an MC Unit and the support tool by using a support tool (MC-Miel) or
IOWR/IORD instructions.
Specify position data at the following addresses in MC Unit memory. Specify
the addresses in hexadecimal when using IOWR/IORD instructions.
Data IORD/IOWR control Address
Position Data 0000 to 27FF Hex (deci-
mal:0000 to10239)
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
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.
