Circuit blocks which cannot be written
during RUN
Circuit blocks in which labels P and I are added, deleted or changed in edited circuits
Circuit blocks in which 1-ms timers (T246 to T249 and T256 to T511) are added in edited circuits
Circuit blocks in which the following instructions are included in edited circuits
• Instruction to output high speed counters C235 to C255 (OUT instruction)
• SORT2 (FNC149), TBL (FNC152), RBFM (FNC278) and/or WBFM (FNC279) instruction
Circuit blooks which require attention
on operation after writing during RUN
During RUN, avoid writing to a circuit block including the following instructions under
execution. If writing is executed during RUN to such a circuit block, the PLC decelerates
and stops pulse output.
• DSZR (FNC150), DVIT (FNC151), ZRN (FNC156), PLSV (FNC157) instruction [with
acceleration/deceleration operation], DRVI (FNC158) and/or DRVA (FNC159) instruction
During RUN, avoid writing to a circuit block including the following instruction under
execution. If writing is executed during RUN to such a circuit block, the PLC immediately
stops pulse output.
• PLSV (FNC157) instruction [without acceleration/deceleration operation]
During RUN, avoid writing to a circuit block including the following instructions under
execution of communication. If write during RUN is executed to such a circuit block, the
PLC may stop communication after that.
If the PLC stops communication, set the PLC to the STOP mode once, and then set it to the
RUN mode again.
• IVCK (FNC270), IVDR (FNC271), IVRD (FNC272), IVWR (FNC273) and/or IVBWR
(FNC274) instruction
During RUN, avoid writing to a circuit block including the following instruction under execution.
If such writing is executed during RUN, instructions being executed are canceled.
• FLCRT (FNC300), FLDEL (FNC301), FLWR (FNC302), FLRD (FNC303),
FLCMD (FNC304) and/or FLSTRD (FNC305) instruction
