Hello all, Looking for a bit of general guidance for how to spec a CPU for a project, and possibly some direct advice on this project. IO wise I am looking at 128 DI, 88 DO, 16 AI and 4 AO, plus a SIWAREX WP521 ST strain gauge module and a single software PID control loop. This will be split roughly evenly between a primary station with the processor and a remote I/O station using an ET200MP. I have currently picked a CPU 1513F-1 PN, but am not sure how to judge if it is up to the task! Looking here https://new.siemens.com/global/en/products/automation/systems/industrial/plc/simatic-s7-1500/cpus.html it looks like a 1513 or a 1515 would likely do it but I am not sure what counts as a small or medium project? Thanks in advance, David McC |
