Good morning.

I've got the following CPU:

And if I go to "Cycle/Clock Memory" tab, I'll see, that I have 256 bytes for each area set by default:

Please, tell me what's the maximum available size I can set for the input and output areas? What should I check and where to look at to determine the maximum for those values? Is it 1MB mentioned at the first picture in the CPU description? Does it mean I can uplift the values to 512k each area?

Check CPU specification for process image size.

In your case it is 8kB inputs and 8kB outputs.

hi.

to know the maximum size of PII & PIQ for plc,you need to get online in hardware window and then double click on cpu,after that you must choose memory tap,now you can see maximum size of PII and etc ..
