The basic instructions achieve a processing speed of 0.045 µs and beyond. – The high-speed instruction processing capability of the F3SP22- 0S makes it ideal for applications that require high speed and quick response. (Scan time is 1ms for 6 K steps of program.) (Application instructions, such as analog I/O that read from and write to advanced modules can achieve a speed of 40 µs and beyond.) – The sensor control function allows one CPU to perform another scan (input, program execution and output) besides the main scan simultaneously, realizing a steady I/O response of 400 µs. – The use of index modification and an object ladder language simplifies program design and maintenance. – The module permits reconfiguration of device size and operating mode according to the application in use. – A user can create and register new instructions. – Program debugging and maintenance can be easily performed using a rich set of functions such as forced set/reset that takes effect regardless of the result of program execution. – Sampling trace features are provided that can collect and display the status of multiple devices with a maximum of 1024 scans. – The programming tool link port is provided with a personal computer link feature, which allows the F3SP22-0S to connect to a higher-level computer or display without a personal computer link module. (The maximum communication speed is 115 Kbps) – High-reliability design and powerful self-diagnostics are provided. Errors detected during program execution can be logged with predefined messages. – Program data is saved to memory, which is backed up with a battery that has a long service life and does not require maintenance. – Programs and data can be made resident in an optional ROM pack, which facilitates program modularization. – Programs can be protected using a protection feature. This can prevent a third party from viewing, modifying or copying programs. – When installed in slot 2, 3 or 4, the F3SP22-0S functions as an add-on sequence CPU module. – Structures allow a user to easily reuse data. – Circuit comments, subcomments, tag name definitions (including I/O comment) can be saved in the CPU program area, improving maintenance efficiency. – Indirect designation and input macro instructions facilitates standardization and modularization of programs. – The partial download function improves debugging efficiency.
