Example
The analog inputs terminal 8 and terminal 6 are to be connected (division) via the
arithmetic block 2 and then be assigned to the code C046 ”main set-value”.
Procedure
( Select C145 = -4-, terminal 8
( Assign C146 = -14-, arithmetic block 2 input 1
( Select C145 = -3-, terminal 6
( Assign C146 = -15-, arithmetic block 2 input 2
( Select C145 = -10-, arithmetic block 2
( Assign C146 = -1-, main set-value (C046)
( C191 = -4-, division: select input 1 / input 2 (C338 / C339).
3. Functions
For all arithmetic blocks the following functions can be preselected (example for
arithmetic block 2):
with C191 = -0-, output = C338 (C339 not processed)
with C191 = -1-, output = C338 + C339
100% = 50% + 50%
with C191 = -2-, output = C338 - C339
50% = 100% - 50%
with C191 = -3-, output = C338 : C339
100% = 100% : 100%
with C191 = -4-, output = C338 / |C339|
1% = 100% / 100%
with C191 = -5-, output = C338 / (100% - C339)
200% = 100% / (100% - 50%)
