Hi, I'm very new to PLC's. I'm trying to understand a program that someone else has written. I having trouble understanding the LIM (limit test)I understand where the High Lim and Low Lim come from, but where does the value for the 'Test' come from. I'm looking at a program that has
low lim 4000
4000<
Test I:7.0
12234<
High Lim 20000
20000<
I understand that I:7.0 is an address input but, where does the 12234 come from. Is that a value from the input? Could you please explain the 'Test' part of the LIM (limit test). Thanks ~Snide
