Standard function blocks329Standard function blocksWhat this chapter containsThis chapter describes the standard function blocks. The blocks are groupedaccording to the grouping in the DriveSPC tool.The number in brackets in the standard block heading is the block number.Note: The given execution times may vary depending on the drive application used.The block execution time describes how much CPU load (1.21 CPU USAGE) theblock reserves. For example, if a block with the execution time of 2.33 μs is set to a1 ms time level, the increase in the CPU load will be 0.23%.TermsData type Description RangeBoolean Boolean 0 or 1DINT 32-bit integer value (31 bits + sign) -2147483648…2147483647INT 16-bit integer value (15 bits + sign) -32768…32767PB Packed Boolean 0 or 1 for each individual bitREAL -32768,99998…32767,9998REAL24 -128,0…127,99916-bit value 16-bit value (31 bits + sign)= integer value = fractional value8-bit value 24-bit value (31 bits + sign)= integer value = fractional value
