# Appendix 2 How To Find Buffer Memory Addresses - Mitsubishi Electric RD77MS2 User Manual

Melsec iq-r simple motion module.

Appendix 2
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.100 are assigned to each axis. Positioning data has the following structure.
data No. 2
Positioning data No. 1
Positioning identifier
6000+1000n
[Da.1] to [Da.4]
[Da.10] M code/Condition data
No./Number of LOOP to LEND
6001+1000n
repetitions/Number of pitches
[Da.9]
Dwell time/JUMP destination
6002+1000n
positioning data No.
Positioning option
6003+1000n
[Da.27] to [Da.29]
[Da.8]
6004+1000n
Command speed
6005+1000n
[Da.6]
6006+1000n
6007+1000n
movement amount
[Da.7]
6008+1000n
6009+1000n
Axis to be interpolated No.
71000+1000n
71001+1000n
[Da.20] to [Da.22]
n: Axis No. - 1
When setting positioning data using a program, determine buffer memory addresses using the following calculation formula
*1
+ (1000  (Ax - 1)) + 10  (N - 1) + S
• 6000
*1 The value is 71000 when setting "[Da.20]" to "[Da.22]".

Up to 100 positioning data items can be set (stored) for each
axis in the buffer memory address shown on the left.
No.101 to No.600 are not allocated to buffer memory.
Set with the engineering tool.
Data is controlled as positioning data No. 1 to 600 for each axis.
One positioning data item is configured of the items shown
in the bold box.
