hi, does this mean that you have 30 signals per revolution and ,with a maximum of 60rpm, up to 30 signals per second. that means a signal changes every 33ms from 0 to 1 and back to 0. The module might can handle it, but the OB1-cycle is the bottleneck here. It is too fast to do it with a "normal" DI-card. You need a counter-module, like 6ES7138-4DA04-0AB0 hope this helps, regards, |
