Accessing from BASIC
Using the PC Link Module with the personal computer link function to access the
common area of a BASIC CPU module does not require creation of a program on the
BASIC CPU. The BASIC common area can be directly accessed as D registers and I
relays. For details, see the description on the device access commands for BASIC
CPUs in Section 1.3 of the Personal Computer Link Command Instruction Manual
(IM34M6P41-01E).
When using the PC Link Module for event transmission, or when performing software
setting of the module, access it as follows:
(1) Declaring the use of the module.
Before you use the module, you must declare its use using the ASSIGN statement.
Always execute the ASSIGN statement before accessing the module (using
ENTER/OUTPUT/STATUS/CONTROL statements).
ASSIGN LC11 = SL (for F3LC11-2F)
SL: Slot number (numeric value, or numeric variable)
(2) Accessing X and Y relays
Access the input (X) and output (Y) relays of the module in units of 16 points (1
word).
- Reading from input relays
To read from input relays, use the STATUS statement.
STATUS SL, n; P
SL : Slot number
n : Data position number (101: Xlmm01 to Xlmm16; 102: Xlmm17 to Xlmm32)
P : Variable for storing read data
