$VAR_NAME Meaning: Character string indicating the data to be assigned.
When assigning a register, specify, for exammple, R[1]. The number in brackets is a
register number.
Consecutive registers such as R[2] to R[5] can be assigned at one time. In this case, the
number of the registers is four, so set 8 in $SIZE and set R[2] in $VAR_NAME. Here, the
index 2 indicates that registers are assigned sequentially from R[2].
The number of %R’s per register can be set ti 1 by adding @1.1 to the end of the
character string. In this case, 16-bit data is used.
Example: R[1]@1.1
R[1] indicates that registers are assigned sequentially from R[1]. @1.1 indicates that
data is used as 16-bit data.
$MULTIPLY Meaning: Multiplier
The register value is multiplied by the value set in $MULTIPLY, then the multiplication
result is read or written.
When $MULTIPLY is set to 0, it has a special meaning. %R can be read and written as
32-bit real type data.
When $MULTIPLY is set to non-zero value, 32-bit signed integer data is used, with its
fractional part rounded off.
Range: 0.0001 to 10000, 0
Example: Suppose that the register value is 123.45:
When $MULTIPLY is 1, 123 is read.
When $MULTIPLY is 10, 1235 is read.
When $MULTIPLY is 0.1, 12 is read.
When $MULTIPLY is 0, 123.45(real number) is read.
An example of setting $SNPX_ASG is given below:
$ADDRESS $SIZE $VAR_NAME $MULTIPLY
$SNPX_ASG[1] 1 2 R[1]@1.1 1
$SNPX_ASG[2] 3 4 R[1] 100
$SNPX_ASG[3] 7 4 R[2] 0.1
$SNPX_ASG[4] 11 2 R[1] 0
Then, the %R-to-register correspondence is follows:
PLC address Robot controller data that can be read and written
%R1 16-bit signed integer of R[1]
%R2 16-bit signed integer of R[2]
%R3-4 32-bit signed integer obtained by multiplying R[1] by 100
%R5-6 32-bit signed integer obtained by multiplying R[2] by 100
%R7-8 32-bit signed integer obtained by dividing R[2] by 10
%R9-10 32-bit signed integer obtained by dividing R[3] by 10
%R11-12 32-bit real number of R[1]
$SNPX_ASG[1] indicates that two %R’s, %R1 and %R2, are
assigned to registers sequentially from R[1] in the format of 16-bit
signed integers multiplied by one. Since $R is 16-bit data, the number
