Hi all, I have a hassle with a ML 1500 and BWA related to this thread. We've just purchased the PLC for a small bottle filling application and cant get the 2nd HSC working properly. What we see from the manual is HSC 0 uses inputs 0-3 and HSC 1 uses inputs 4-7. But looking at the I/O config for the embeded inputs looks like the smallest filter is 500us limiting the HSC to 2khz. Are we doing something wrong here?? Can other inputs on the 0-3 bank be used for counter one ?? If so then how do we configure them. Cheers Malcolm Joburg South Africa
