PLC FX3U FX3U FX3U DDRVI JOG Y001 (K999999 K1000 Y000) and DDRVI K1000 (D200 Y001 Y000) 2 DDRVI instructions, the test found when the automatic positioning instruction in the positioning process in the positioning process of the JOG (DDRVI), and sometimes JOG PLC, M8348 conditions are set up M8340 and ON for OFF, JOG conditions are normal. At the same time when the ON is not normal, M8312, why is it?

Hello, Based DDRVI command on DDRVI command the above, the suspect could be Y0 is driven by multiple location directive at the same time. Proposed PLC without the time, connect programming software Diagnostics-PLC Diagnostics, see if there is error.
Secondly, M8312 is a real time clock time data loss bug, but M8312 support FX3G,FX3S PLC, FX3U PLC are not supported, so not working has nothing to do with the M8312.
