imanERC Posts: 15 Rating: (0)	Hello I have a plc314 with this order no. 6ES7 314-1AE03-0AB0 and has 32KB memory card.This Plc has 24KB work memory and 40KB RAM. This Plc was programmed by someone and I want to reprogram this cpu for extra porpose.So I place 256KB memory card In this cpu and buy a communication processor with this order no. 6GK7 343-1EX30-0XE0.I modify configuration for placing the CP on the rack.Finally I have a rack with cpu and some digital input/output and analog input/output and the CP.I design a new program and place some FBs abd FCs and DBs at the old program.The new program size is about 100KB so When I want to download the program to the cpu this alarm was indicated:[download(294:38)-possible load memory bottleneck or not enough memory on memory card.Do you still want to continue?(required/free/total memory=48832/40296/40960 bytes)].And when I want to download program to memory card from program window toolbar(plc>download program to memory card) anoder error message was indicated,As I said I use 256KB memory card and it seems there is not any errors but…,So for download directly to memory card is it necessary use prommer or the cpu has some restriction or the download way is incorrect?So What should I do?I should change the cpu or memory card or program or something else?please guide me.Thanks a lot.

User blocks require space both in work memory and load memory - could you check an amount of work required for your programm? S7Manager->Blocks->right_click->Properties.

imanERC Posts: 15 Rating: (0)	Hello Thanks for your attentiond.As I said I have plc314 and I should just use MC not MMC,it is an old version of cpu314(6ES7 314-1AE03-0AB0) and memory card.So here there is an information you want: ------------------------------------------------------------------ size in load memory 48324 bytes size in work memory code 31738 bytes date 3620 bytes Total 35358 bytes system data memory 664 bytes ------------------------------------------------------------------ So now what should i do?I should change the downloading way or change CPU or change memory card?As I said i use 256KB flash MC for this cpu instead of its 32KB MC.Please Guide me. Another question is:when I want use simatic usb-prommer to download program to MC,at first I determine port in Memory Cars parameter Assignment in control panel then open the S7 manager and program window and click file>S7 memory card>open.I install prommer driver corectly.By this way I cant acsses to the Memory Card ant this Error is indicated:Function not Impemented.So for solve this problem what should I do? Please answer my Two Question. Thanks A lot. Iman

Aret Posts: 2348 Rating: (265)	This Plc has 24KB work memory Total size of program in work memory - 35 kB. The only you can do: change CPU or decrease program size. I'll repeat once again WORK memory is NOT EXTENDABLE. At all. No way As for your second question - please specify what do you use - is it Siemens PG or PC+Siemens usb-cardreader or PC+Siemens usb-adapter (MPI/Profibus)?

Aret Posts: 2348 Rating: (265)	Ok, seems you have 6ES7792-0AA00-0XA0. Whatfor do you need to open MMC card? If you want to delete all blocks on PLC - just open project online (2nd icon to the right from download icon) and delete them. To be honest i didnt use prommer, but used PG. Operations were quite simple - insert MMC card in corresponding slot of PG - then File->S7 memory card->Open from simatic manager.... If after these actions it doesn't work properly - i can advise anything further.

imanERC Posts: 15 Rating: (0)	Hello Thank your for your advise,About the question that what I want open the MEM-card is that I want to program the memory card apart from PLC and then insert this 256KB in PLC314 slot because of solving that problem we discuse,I am searchin way which can solve my problem becuse it is not economical for me to change the CPU314 because of low work memory,But if there is not any way I must change the cpu to 315.My OS is windows XP+SP2,is it cause problem to read and write from prommer.Please inform me. Thanks Iman

Aret Posts: 2348 Rating: (265)	Do you want do download blocks directly to MMC (via copying by prommer) and then insert it CPU thus avoiding download bottleneck? Think it won't work, because to implement blocks they must be in work memory, and you work memory is not enough. Guess you should reorganize your program. Also check if unlinked property of DBs can be set for some DB according to your application.
