Conversion Of Special Relays - Panasonic FP7 Series Additional Functions Manual

4.2 Conversion of Special Relays

When using special relays on a conventional model, address conversion is performed in
accordance with the conversion rule for converting programs to FP7.
 Conversion rule
(1) Only for convertible special relays, address conversion is performed.
(2) As only similar device items are converted, the device addresses after R902C cannot be
converted.
(3) Word accesses (from WR900) cannot be converted.
 Operation when an instruction cannot be converted
Converts instructions leaving inconvertible device numbers unchanged, and sets "network to
be excluded from execution".
Example) Before converting an FP2SH program
Example) After converting the program to FP7 program
In the above example, the device addresses R9001 to R9003, and R9005 are the output
results of inconvertible items.

