SLAVEREG SLAVEREG is the start of the area in the addressed slave from which the source
data is read. The source area always resides within the %MW word (4x register)
area. SLAVEREG expects the source reference as offset within that area. In 4x
registers, the leading 4 must be omitted. For example, 59 (contents of the variables
or value of the literal) = 40059.
The parameter can be specified as direct address, located variable, unlocated
variable, or literal.
NO_REG Number of registers to be read from the addressed slave (1 ... 100).
The parameter can be specified as direct address, located variable, unlocated
variable, or literal.

registers used as source data area.
The parameter must be entered as a direct address or located variable.
