High-speed input / output function
The high-speed input / output function of the SJ series has been greatly enhanced.
Dedicated instructions are provided for the high-speed counter function and motion control function, making it extremely easy to use.
Input / output function settings can also be easily set from KPP.
If the high-speed counter function is used in the SJ series, the program in this part cannot be diverted, so it is necessary to change the program by referring to the following manual.
CPU built-in analog input / output setting method
Special register for setting the function of analog input / output with built-in CPU: The specification method of R7600 is different.
In addition, SJ-ETHER can be set not only from R7600 but also from KPP’s I / O configuration function.
