DATA CONVERSION
■ COUNT VALUE
The count value is 32-bit data. It is divided in 2 words of 16 bits represented with 2 addresses.The lower address is
allocated in the upper word (MSB) and the upper address in the lower word (LSB). The count value is 0 - 4 294 967 295.
The maximum count value available is 1 000 - 4 294 967 295. In case of overflow, the vaule is reset to 0 or 1
(configurable) from which the count will restart. The preset of the count value is also available. Use the R7CON or
host PC/PLC for the configuration.
