	Hellow everybody I have one problem with saving new program into PLC. We have a machine that have an OMRON programmable controllers C200HE-CPU. When I put new working program and in PLC I confirm to save it and when I turn OFF the machine and back ON, the inserted program doesn`t exist. Inside the controller there are only the old program which were inserted in the past. We change the battery in controller with new one and the problem persist. It is possible that is has some switch which enable/disable writing new programs? Appreciate your help Have a nice day

	Some brands of PLCs have NVRAM, or "Non-Volatile Random Access Memory", in them besides their regular RAM. So... if you have such a CPU module, on power up it looks to see if a program is in NVRAM. If it finds a program in NVRAM, it copies that program to RAM and runs that program. This feature is to ensure that a "baseline" program is always present and used on power up from black. Sounds to me like that is what you have. If so... you must copy the program from running RAM to the NVRAM before powering it down. Then upon restart, the proper program is found in NVRAM, then copied to RAM and away you go. __________________ Joe Contractor to Electrical Inspector, "What do you mean you are going to make me follow the code?".

	Thank you for the answer I check with the company that produce this PLC and also the company that produce panels and the problem is in the panel. The panel has his own memory, which has the program (recipy) and the problem is that I can not save new program. It is possible that the company insert the old program and lock the memory for future writing? or is this common for this type of panel the panel is EXOR R&D T-line; model: TCP05R-04-0345 the panel doesn`t have inside any battery
