Output Registers/Coils (Y, YW)
These registers and coils are designed for use by the physical outputs (digital or analog) from an
attached or built-in (HMC7030A-L) output expansion module. The value read from these
internal registers/coils is used to determine and set the current state of the physical output of
the expansion module assigned to it. When you start a new project and assign I/O expansion
modules to each expansion slot of the HMC, the MAPware-7000 will automatically assign the
appropriate memory addresses according to slot location. For example, the eight built-in digital
outputs of the HMC7030A-L are assigned to coils Y00000-Y00007 and register YW0000. For a
HMC7000 unit that has eight digital outputs in expansion slot #1, the MAPware-7000 software
automatically assigns coil addresses Y01000-Y01007 and register YW0100 to the outputs. If
twelve digital outputs are located in slot#3, the software assigns coil addresses Y03000-Y03011
and register YW0300 to the outputs. If an analog module with two analog outputs is installed
into slot#5, then no coil addresses would be assigned (since these are analog outputs) and
registers YW0500-YW0501 are assigned.
The Y and YW registers are mapped to the same memory area in the HMC with sixteen Y coils
per YW register. For example, Y161 corresponds to the second least significant bit (bit 1) of
YW0010.
IO Registers/Coils (M, MW)
These registers and coils are reserved to perform special functions when the HMC7000 has built-
in or attached expansion modules. For example, the HMC7030A-L has the following I/O
Register/Coil memory allocated for the twelve digital inputs and eight digital outputs built into
the unit:

M00240 HSC Enable Bit (ch1)

M00241 HSC Reset Bit (ch1)

M00400 HSC Enable Bit (ch2)

M00401 HSC Reset Bit (ch2)

MW0000 PLC mode control

MW0003 Run/Stop Switch

MW0010 HSC Configuration Register (ch1)

MW0011 HSC Current Register (ch1)

MW0013 HSC Preset Register (ch1)

MW0020 HSC Configuration Register (ch2)

MW0021 HSC Current Register (ch2)

MW0023 HSC Preset Register (ch2)
These registers are used when the built-in I/O of the HMC7030A-L is configured as high speed
counters.
The MAPware-7000 automatically allocates the necessary IO registers to each expansion module
according to slot location and type of module. For example, a HMC7000 unit that has eight
digital inputs and eight digital outputs in expansion slot #1 has coil addresses M01080, M01081,
M01176, and M01177 and registers MW0100-MW0109 assigned for two high-speed counters.
