As for individually writing parameters via CC-Link, changing OUT area values constitutes a write request. In your case, since the OUT area value hasn't changed from the previous value, the SP value is notoverwritten. As a fix, periodically copy the current SP value (IN area CSP_L1) to the OUT area SP_L1_1 on the MELSEC. As a result, the OUT area value is updated by the reloaded SP value, and the SP value can be overwritten.
