6-6-2 Memory Area Designations

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.
