MLC Maintenance -- C,S Bits and Register
R Register Definition Remarks
Read/Write Value (different depends on R60~R62)
R60:1,means 4th axis absolute coordinate um
part;
R60:2,means 4th axis machine coordinate um
70 part;
Please refer to Attention.
R60:3,means the present value of the1 st macro
global variable that is designated by R61 and R62.
R60:4,means the value of 1 st parameter that is
designated by R61 and R62.

MLC to R63~R76 Reading
Attention:
1. For read only items, if Ladder sets C64 to 1, NC will ignore it. Using the same principle
for the writing items, if Ladder sets C64 to 0, NC will ignore it.
2. Macro variables belong to DOUBLE type. But the present Ladder can only take care of
the value in INT type. So if Ladder reads macro global variables via MLC Window, NC
will check whether or not the macro global variable value is between -32768 ~ 32767.
If yes, the macro global variables will change to INT type and then enter into the
corresponding R register. If no, then the alarm 【 OP 1019 DESIRED MACRO
VARIABLES OVER RANGE】will occur.
3. Using R61 and R62, Ladder can read/write multiple macro global variables (maximum
8 variables) continuously. Example: set R60 to 3, R61 to 200 and R62 to 5. When C64
is OFF, it means the total current value of the designated reading/writing @200 ~
@204, total 5 macro global variables. But, if (R61 + R62 – 1) > 500, then alarm
message【OP 1018 DESIRED MACRO GLOBAL VARIABLES NOT EXISTED】will
occur.
4. Macro local variables not able to execute read and write via MLC Window.
5. The reading parameter value must be an integrate number (INT) or long integrate
