• REGISTER TABLE
MAPPING BE1-851 PARAMETERS INTO MODICON HOLDING REGISTER
ADDRESS SPACE
General
Parameters are mapped into the holding register address space (40001 - 49999) in blocks according to
access type.
Any Holding Register not listed in the Register Table is an unassigned Holding Register. A value of zero
always results when reading an unassigned Holding Register. Writes to unassigned Holding Registers
are legal, but no action will be taken (the write is ignored).
