Operation example 5: Writing to the RAM area, turning the power off and on, and then writing the
same value to the normal memory area
(1) Turn the C7G on. The Loop1 LSP group 1 LSP is 100.00.
(2) Write 200 to data address 1007 (RAM area) via communication.
The Loop1 LSP group 1 LSP changes to 200.00.
At this time, RAM has "200.00" and the normal memory area has "100.00."
(3) Turn the C7G off and then on again.
The Loop1 LSP group 1 LSP changes to 100.00.
At this time, RAM has "100.00" and the normal memory area has "100.00."
(4) Write 200 to data address 1008 (normal memory area) via communication.
Because this value is different from the value in RAM, it is written to the
normal memory area.
The Loop1 LSP group 1 LSP changes to 200.00.
At this time, the value in RAM is 200.00, and the value in the normal memory
area is 200.00.
(5) Turn the C7G off and then on again. The Loop1 LSP group 1 LSP is 200.00.
