How Can i sove the error "Out of global Data Memory ,Variable SP_C12 , 228 Bytes ?
I do have a project with the eCO AC500 PLC
At a stage of the programming I have the following Error massage
Out of global Data Memory ,Variable SP_C12 , 228 Bytes
what is that means ? how can I solve that ?
Its quite a common problem. As you add code and make commissioning changes, the old memory areas do not get "cleaned up", and your global variable memory usage increases.
You need to "Project -> Clean All" the program and then "Project -> Rebuild All". You then need to download the program to the PLC again. Be aware the PLC will warm start when you do this.
Really, the eCO memory is quite small so you should allways do this before you save a boot project and you definitely should do this when you have finshed commissioning.
