Type I Variable Read (0110)
3.5.3.6
(1) Function
This command outputs to the status area the value of the Type (integer
type) global variable of the number specified in data area 1.
(2) Format
Command area (4 bits, input)
0110
Data area 1 (8 bits, input)
The number of the Type I variable for which a value will be substituted.
Any number between I [0] and I [255] can be specified. When the input
data in data area 1 is nn, the value specified in data area 2 will be
substituted for the Type I variable I [nn].
Data area 2 (16 bits, input)
Nothing will be input.
Status area (16 bits, output)
The lower 16 bit value of the Type I variable specified in data area 1 will
be output.
(3) Description
The value of the Type I variable specified in data area 1 is output to the
status area.
Although the Type I variable has a storage area of 32 bits, the lower 16
bits will be output to the status area.
Therefore, any value between -32768 and 32767 can be output properly.
However, if the value is out of this range, only the lower 16 bits of the data
will be output.
