Hello, The last couple of days I'm collection information for the selection of a new cpu which runs under pcs7.1. I can't figure out which CPU we need to choose.. It is also important for feature purposes because now I only do single client OS with one AS. For the feature, there will be two OS stations with redundant server and possibly another CPU. Think of a time span for 1 year or so... I came up with two selections... The 417 I think has too much overhead, since the total I/O is 1000, with six ET200M + a few s7300 CPU's and a total of 800 I/O for exchanging data to/from drives. Let's say that we need three more ET200m fully equipped in the future... Further, the actual data size of the program is as follows: - System data memory = 22534 bytes - User program memory->Load memory = 1284342 bytes - User program memory->Work memory = 1023204 bytes I'm halfway with the project. It is difficult to determine. So far, I didn;t find any good guidelines when selection a cpu... Can somebody point me in the right direction? Thank you |
