Variables
Section 4-3
Note (1) For Position Data, see 4-4 Position Data (Page 107).
(2) For System variables, see 4-5 System Variables (Page 111).
(3) For Input variables and Output variables, see 4-6 I/O Variables (Page
160).
(4) CAM Data will not be treated as a variable.
Rules for Writing
Variables Use the following format to write variables.
Put # in front of variables.
V: Variable type
T: Data access type
hhhh: Addresses of Data (in hexadecimal)
b: Bit number for bit-type data access (in hexadecimal)
Example)
#PL0000 = 10000;
MOVE_[J01]#PL0000;
Variable Type and
Address Range Use 4-digit hexadecimal notation for data addresses.
Data addresses indicate the first address of integer data regardless of the
access type.
Note Task variables can use 128 words in each task.
Data Access Type There are four data access types as shown in the following table.
Variables exclusively for tasks
Task variables Can be used only in each task, and are used
as workspace, etc. during operations. 128 words
