Appendix 3 How To Find Buffer Memory Addresses - Mitsubishi Electric MELSEC iQ-R-RD75P4 User Manual

Appendix 3
This section describes how to find the buffer memory addresses of positioning data, block start data, and condition data.
Positioning data
Positioning data No.1 to No.600 are assigned to each axis. Positioning data has the following structure.

• Up to 600 positioning data for each axis can be set (stored) in
the buffer memory addresses shown on the left. These data are
controlled as positioning data No.1 to No.600 for each axis.
• One positioning data is configured of the items shown in the
bold box.
