In Comparison Mode every Counter can be assigned up to a maximum of 32 Com-
parison Values. The Data of every Comparison Value (CV-Data) is contained by 5
double words:
•
Comparison Value (can be set between 80000000
Counter and between 00000000
•
Output Set Pattern for the positive counting direction (+Set Pattern CV'n'),
specifying which Outputs must be Set on reaching that CV in the positive
counting direction (0 = No Change, 1 = Set Output)
•
Output Reset Pattern for the positive counting direction (+Reset Pattern
CV'n'), specifying which Outputs must be Reset on reaching that CV in the
positive counting direction (0 = No Change, 1 = Reset Output)
•
Output Set Pattern for the negative counting direction (-Set Pattern CV'n'),
specifying which Outputs must be Set on reaching that CV in the negative
counting direction (0 = No Change, 1 = Set Output)
•
Output Reset Pattern for the negative counting direction (-Reset Pattern
CV'n'), specifying which Outputs must be Reset on reaching that CV in the
negative counting direction (0 = No Change, 1 = Reset Output)
To configure a Counter in Comparison Mode for every Comparison Value that you
want to use the CV-Data must be set. Each data-item is specified by two words
(=32 bits). For the exact memory location of the CV-Data, refer to 4-2-1 "Memory
Mapping".

In the +/- Set and Reset Patterns the Outputs are represented by:
= Digital Outputs 0-1
(corresponding with Physical Digital Outputs O0 and O1)
= Soft Outputs 2-31
