8.4.5.2 Process-data softwiring in the units
Process data interconnection involves the linking up of setpoints and
control bits to the RAM interface. The transferred process data only
become effective when the used bits of the control words as well as the
setpoints, status words and actual values are allocated (connected) to
the dual-port RAM interface.
The received process data are stored by the CBC 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.
With the help of selector switches (e.g. P554.1 = selector 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. In
order to do this, the connector belonging to the required PZDi is
assigned to the selector switch.
In function classes CUPM, CUMC, CUVC and Compact PLUS, the
control words STW1 and STW2 are also available in bit form on so-
called binectors (explanations of BICO systems can be found in
Chapter 4 "Function Blocks and Parameters").
