Hello again.
I`m still stuck with the analogue-part of my program and
hope you could answer a couple of questions.
I use the FC105-block to read and scale analogue value.
Let`s go through the block one-by-one.
1. IN, here comes the analogue value from the analog-input, for example PIW130 etc.?
2. HI_LIM this is high value of my scaled analogue?
3. LO_LIM and this is the low value?
For example I have a analogue thermometer which gives me a signal between 4-20mA. I want to use a temperature between 0-50 degrees.
So do is set the LO_LIM to 0 and HI_LIM to 50, or are these values for something else?
Next the BIPOLAR, what is this used for? It`s either on or off.
Is BIPOLAR for example needed if I use +- 5V instead of 4-20mA
or for something else?
4. RET_VAL, where does this lead to?
5. OUT, is this the scaled output value which I then can
move to a DB and then process from thereon?
I`ll put a linki which shows the block, which I hope to simplify what I mean

Thanks in advance!
