GENERAL OPERATION
16 PLC Access to Drive Setup Parameters 12/22/94- RD 3196-10
There are two types of PAC blocks which can be used with the PLC
initialization command. These are the GETN and RDCI blocks which allow
the programmer to define drive setup parameters, each of which has a unique
"function" number. The vaules of these setup functions can be changed from
the drive, and can also be accessed by devices on the drive network such as the
PLC gateway.
Figure 9 shows the relationship between an RDCI PAC block and the PLC
initialization table. A GETN block would be handled the same way. The PLC
initialization table refers to this RDCI by its function number (115).
