GFK-0467K Chapter 4 Series 90-30/20/Micro Instructions Set 4-71

Parameters:
Parameter Description
enable When the function is enabled, the move is performed.
IN IN contains the value to be moved. For MOVE_BIT, any discrete reference may be
used; it does not need to be byte aligned. However, 16 bits, beginning with the reference
address specified, are displayed online.
ok The ok output is energized whenever the function is enabled.
Q When the move is performed, the value at IN is written to Q. For MOVE_BIT, any
discrete reference may be used; it does not need to be byte aligned. However, 16 bits,
beginning with the reference address specified, are displayed online.
LEN LEN specifies the number of words or bits to be moved. For MOVE_WORD and
MOVE_INT, LEN must be between 1 and 256 words. For MOVE_BIT, when IN
is a constant, LEN must be between 1 and 16 bits; otherwise, LEN must be between 1
and 256.
Note
On 351, 352 and 360 series CPUs, the MOVE_INT and MOVE_WORD
functions do not support overlapping of IN and Q parameters, where the IN
reference is less than the Q reference. For example, with the following values:
IN=%R0001, Q=%R0004, LEN=5 (words), the %R0007 and %R0008 contents
will be indeterminate; however, using the following values: Q=%R0001,
IN=%R0004, LEN=5 (words) will yield valid contents.
Also, please note that only 350 and 360 series CPUs (Release 9 and later, plus all
releases of CPU352) have Floating Point capabilities at this time and therefore
the only one capable of MOVE_REAL.

Note: For REAL data, the only valid types are %R, %AI, and %AQ.
• Valid reference for BIT, INT, or WORD data, or place where power may flow through the function.
For MOVE_BIT, discrete user references %I, %Q, %M, and %T need not be byte aligned.
o Valid reference for BIT or WORD data only; not valid for INT.
† %SA, %SB, %SC only; %S cannot be used.
