The following table gives the addresses to use when reading or writing PLC
data. The Data area address column gives the normal addresses used in the
PLC program. The Address used in communications column are the
addresses used in CV-mode commands and responses. These addresses
are combined with the memory area codes to specify PLC memory locations.
These addresses are not the same as the actual memory addresses of the
data.
The No. of bytes column specifies the number of bytes to read or write data for
that area. The number of bytes varies for the same area depending on the
memory area code. Actual data area sizes vary with the PLC being used.
Refer to your PLC's operation manual for specific limits.
