*1 The points are fixed for the system. (Cannot be changed)
The points for the step relay can be changed to 0 if the Universal model QCPU whose serial number (first five digits) is
"10042" or later.
For the Universal model QCPU whose serial number (first five digits) is "12052" or later, a step relay can be set in
increments of 1k point and up to the following points. (
• Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU: 8192 points
• Universal model QCPU other than the Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU: 16384 points
*2 Up to 32K points can be set for each device.
However, up to 60K points can be set for each device of the internal relay and link relay if the Universal model QCPU
whose serial number (first five digits) is "10042" or later,
*3 Enter the values multiplied (or divided) by the number shown in the Size (words) column.
