Appendix 3 Remote Buffer Memory; List Of Remote Buffer Memory Areas - Mitsubishi Electric NZ2GN2S1-32D User Manual

Appendix 3
This section describes the remote buffer memory.
The remote buffer memory consists of addresses for the error history area and module control data area.
• For a single I/O module, do not execute multiple dedicated instructions at the same time. If multiple
dedicated instructions are executed at the same time, the I/O module may be unable to receive the
dedicated instructions, and the dedicated instructions may time out.
• Do not read or write data from/to any "Use prohibited" remote buffer memory areas. Otherwise, an accident
may occur due to an incorrect output or malfunction.
