Shared Memory Configuration; Memory Configuration For Valid/Invalid Extended Function - Mitsubishi Electric MELFA BFP-A8787-F Instruction Manual

1.3 Shared Memory Configuration

Here, describes the shared memory configuration among multiple CPUs.

1.3.1 Memory Configuration for Valid/Invalid Extended Function

To use the shared memory extended functions, enable the shared memory extended functions with the
parameter "IQMEM".
After enabling the shared memory extended functions, the shared memory is used by extending the robot I/
O area by 0.5 K word.
