Variable
The following variables can be used in macro program.
Item Explanation
Host
address
Use functions (READCMEM and WRITECMEM) for communication when
accessing to the address in the host.
Enclose address in [ ]
Example:
READCMEM($W100,[HOST1:DM00000],100);
‘Read HOST1:DM00000 to DM00099 to $W100 to $W199
PT Memory Bit
Internal memory: $B $B0 to $B32767 (1bit per 1point)
Internal Holding memory: $HB $HB0 to $HB8191 (1bit per 1point)
System Memory: $SB $SB0 to $SB 63 (1bit per 1point)
Word
Internal memory: $W $W to $W32767(16bit per 1point)
Internal Holding memory: $HW $HW0 to $HW 8191 (16bit per 1point)
System Memory: $SW $SW0 to $SW39 (16bit per 1point)
Example:
$W100=$W0+1; ‘Set the value $W0 and 1 added to $W100
Index Index is used for processing bit and word in the PT memory.
Add index to the end of the address and it will processed as [specified
address + index value]
There are 10 index points (I0 to I9).
Set I0 to I9 for the value of $SW27 to $SW36.
Example:
$SW27 = H20;
$W0I0 = 123; ‘$W0I0 is regarded as $W20 added $W0 and 20
‘$W20 = 123
Qualifier of Variable
Qualifiers set for variables must be used as shown below.
Qualifiers are used when performing 32-bit data processing and numeral processing for bit.
Item Explanation
Long Access
(32bit) of
Word (16bit)
Put “L” at the end of variable. Uses 2 words.
$W0L=1000000; ‘Accesses regarding $W0, $W1 as 32-bit
$W100L=1000*1000; ‘Accesses regarding $W100, $W101 as 32-bit
Numeral
Access of Bit
Put “:n” at the end of variable. Specify the value of bit address (up to 32
by 4-bit unit) for “n”.
Exceptions: If n=16, input ”W”.
If n=32, input “L”.
$B0:4 = 3; ‘Sets 3(0011) for 4-bit from $B0 to $B3
$B0W = 12345; ‘Sets 12345(0011000000111001) for 16-bit from $B0 to
‘$B15
