7.2 Overview of Programs
7.2.1 Reading Data From Input Control Area
• The reading program from the unit memories (input control area) reads and stores flags in
the operation memories such as internal relays to enable them to be treated easily in
consecutive control programs.
• Most flags are allocated to 1-word (16-bit) unit memory for 16 axes. As for the limit inputs, 2
bits (+ and - sides) are required for 1 axis, therefore, flags for 8 axes are allocated to 1-word
(16-bit) unit memory.
