Hello Rizal just to be clear, only HWconfig and NetPro download require a CPU restart (downloading ofFC's, FB's,etc are/can bedone in RUN mode and do NOT require a CPU restart).
Yes there is, it is called "Configuration in Run" (or CIR,to be precise, this way you actually avoid a CPU STOP and achieve what you want to achieve). You can find out more about in this manual: Modifying the System during Operation via CiR Alternatively (and this is a "nasty" way), certain DQ and AQ modules(the dearer ones) support the "Keep Last value" and/or "Substitute value" fetaure when the CPUgoes into Stop. You could use this "feature" BUT be aware of the ramifications for your Plant control should your PLC (for whatever reasons) NOT start up anymore after the download!!! Ihope this helps |
