6.1.1 Shared Memory
The S-LINK is equipped with an internal shared memory that enables data to be read from and written to
the control unit.
Function of the shared memory
Information such as the detection of unit (S-LINK device) addresses where errors occur, when they
occur, and the number of S-LINK devices connected to the S-LINK system is stored in the memory. Data
can be read from and written to the control unit using high-level instructions.
Reading data from the shared memory using FPWIN-GR
