3-5-2-2 Configuration and operation in Comparison Mode
Specifying Comparison-
Data In Comparison Mode every Counter can be assigned up to a maximum of 8 Com-
parison Values. The Data of every Comparison Value (CV-Data) is contained by 5
double words:
• Comparison Value (can be set between 80000000
H
– 7FFFFFFF
H
for a Lin-
ear Counter and between 00000000
H
– FFFFFFFF
H
for a Circular Counter)
• 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 section
Section
4-2-1 Memory Mapping.
Note Precautions When Setting Comparison Data
• Comparison Stoppage When Comparison Target Reached
When the Counter Value reaches the target value for Comparison Data,
