PL B4 Result is in Byte 4
L B3 Current switch setting (0 to 7) plus
+ B4 minimum interpolation factor from MP7670
= B5 is new interpolation factor
<= K+10 If the new factor is greater than 10,
JPT 102
L K+10 ... then the new interpolation factor is set
= B5 to equal 10.
LBL 102
PS K+4 Transfer new interpolation factor

Example:
Switch setting: 4
Minimum interpolation factor:
MP 7670 = 5
In this PLC example are the following events:
Inputs: I160 to I162 and I164 to I167 are logically 1
Input: I163 is logically 0
Byte 1: 11110111
Byte 2: 00001000
Byte 3: 3
Byte 4: 5
Byte 5: 8
In the above example, the switch S2 is configured as follows:
Switch setting Interpolation factor
1 (Left-most setting) 5
2 6
3 7
4 8 Present switch setting
5 9
6 10
7 10
8 (Right-most setting) 10
