Hi DaveSeda, This is limit for process input image addresses. If u assign address beyond this range, there will be IO access error in diagnostic buffer. Also SF led will be lit. Significance of the setting- CPU needs local memory for execution of user program. Lesser the value of this setting will result in more local data for CPU execution and performance of CPU will be better. This setting is not available for all controller [not available for smaller CPUs]. This becomes very essential for CPUs with H and FH functionality where more memory required for self tests and diagnostics functions. Hope this helps!!!!!!!!!!!! |
