Please note the information on gain and offset parameters in
Chap
ter 4.3
.6.
Parameters On and Off
The On and Off parameters can be provided by the actual
value
o
f another already-programmed function. You can use
the actual values of the following functions:
• Analog comparator (actual value Ax - Ay, see Chapter
4.4.18)
• Analog trigger (actual value Ax, see Chapter 4.4.16)
• Analog amplifier (actual value Ax, see Chapter 4.4.20)
• Analog multiplexer (actual value AQ, see Chapter 4.4.26)
• Analog ramp control (actual value AQ, see Chapter
4.4.27)
• Analog math (actual value AQ, see Chapter 4.4.30)
• PI controller (actual value AQ, see Chapter 4.4.28)
• Up/down counter (actual value Cnt, see Chapter 4.4.13)
Select the required function by the block number.
