D-(P)(_U) [when three operands are set]
These instructions perform subtraction between the two sets of 32-bit binary data specified.
■Execution condition
■Description, range, data type
• In safety programs executed by the Safety CPU, only safety devices and safety labels of data types described in the table
can be used.
■Applicable devices
• In safety programs executed by the Safety CPU, only the following safety devices and constants can be used.
