Process-data softwiring in the units

Process-data softwiring involves logical connection of the setpoints and
the control bits. The transferred process data come only into effect
when the used bits of the control words, setpoints, status words and
actual values have been routed to (logically connected to) the dual-port
RAM interface.
The received process data are stored by the CBL at fixed, pre-defined
addresses in the dual-port RAM. A connector (e.g. 3001 for PZD1) is
assigned to each item of process data (PZDi, i = 1 to 10). The
connector also determines whether the corresponding PDZi (i = 1 to 10)
is a 16-bit value or a 32-bit value.
The Mitsubishi data structure for converters at CC-Link handles only
16-bit values. So CBL works at the dual-port RAM only with 16-bit
values.
By means of selection switches (e.g. P554.1 = selection switch for bit 0
of control word 1), the setpoints or the individual bits of the control
words can be assigned to a particular PZDi in the dual-port RAM. To do
this, the connector belonging to the desired PZDi is assigned to the
selection switch.
Control words STW1 and STW2 are also available in bits on so-called
binectors within CUMC, CUVC and Compact PLUS. (For an
explanation of the BICO system, see Section "Function blocks and
parameters").
For connecting the MASTERDRIVES converter to CC-Link a defined
set of softwiring has to be done. Additional features (e.g. optional
control and infobits) can be activated by setting additional binectors.
