*1 The number of steps may differ, depending on the device or CPU module to be used.
*2 The conditions under which character string comparisons can be made are as shown below:
CPU module Device Number of
steps
Remark
High Performance model QCPU
Process CPU
Redundant CPU
• Word device: Internal device (except for file register
ZR)
• Bit device: Devices whose device Nos. are multiples of
16, whose digit designation is K8, and which use no
indexing.
• Constant: No limitations
5 When using a High Performance model
QCPU, Process CPU or Redundant CPU,
the number of steps increases but the
processing speed becomes faster.
Devices other than above 3 The number of steps may increase
depending on the conditions.

• Match: All characters in the strings must match
• Larger string: If character strings are different, determines the string with the largest number of character codes. If the lengths of the character strings
are different, determines the longest character string.
• Smaller string: If the character strings are different, determines the string with the smallest number of character codes. If the lengths of the character
strings are different, determines the shortest character string.
