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 NO_REG parameter can be specified as direct address, located variable,
unlocated variable, or literal.
NDR Transition to ON state for one program cycle signifies receipt of new data ready to
be processed.
The NDR parameter can be specified as direct address, located variable, or
unlocated variable.
ERROR Transition to ON state for one program cycle signifies detection of a new error.
The ERROR parameter can be specified as direct address, located variable, or
unlocated variable.

lying in series used as destination data area.
The REG_READ parameter must be entered as a direct address or located variable.
