I do not have the hardware (V2.2 CPU & MMC) to test and tell you what works and what not. So you will have to do the research yourself or convince someone to help you with this. Seeing that I do not get any star rating from you. This is your best option for what you have. The commands to use are READ_DBL and WRITE_DBL, I think. Reading and writing from/to an MMC card is an option you should look into. The 500 variables you speak of is as good as the variables on the PLC. provided that the 10kB is Please could you help filling in the blanks. In my hmuble opinion it will be less hassle if you can get your hands on software and hardware to have the program run on a FW4 PLC. It will take effort for you to get going. A PC or such device can then load the values into the PLC when it is needed. But if all else fails you can go deeper into this option.Īnother option would be to link the PLC in some way to a network. You remember what was said earlier about using a DB for each recipe? (answer by eisenpferdreiter in your previous post) This becomes more complicated to get working than what you have now. What I can say to you is that the handling of the recipes are going to be different (sorry). I think your PLC firmare 2.2 should have these commands. It should be possible to save and retrieve data records to.from MMC type memory card using READ_DBL and WRITE_DBL commands. Any other way of saving my recipes (DBs) permanently ? I am of the opinion that you can make a backup copy to a PC, but the PC can not process it.ĥ. I have not used it myself and doubt on the limitations and doubt on if you can extract it to a computer. The nice thing about FW4 PLC is that it now has ready made commands to write and read data records to the MMC type memory card. Is it possible to tansfer a recipe from memory card to PLC ? each HMI has its own unique limit on amount of recipes and parameters.Ĥ. Or you can look at the specifications yourself. To be more accurate you should tell us which panels you can make use of. Unluckily the amount of data you are currently planning on using may be a problem (opinion). Is there any way to save my PLC DBs to Hmi Data records ? You can read the value from your program and multiply it with what you need to make retentive.ģ. The attached file shows you how you can see how much retentive memory you have used. Firmware 4 is all new hardware.įor FW4 hardware you have to have TIA version 13 also. As your are saying that i've to update my firmware version from 2.2 to 4 so that my retentive memory can be increased from 2kb to 10kb !!!
