4.2 Internal User Devices
Internal user devices can be used for various user applications.
(1) Points for internal user devices
The device points can be changed in the Device tab of the PLC parameter dialog box.
Note 4.1Note 4.2Note 4.3
When changing device points, note the following.
• The number of points for the input (X), output (Y), and step relay (S) cannot be
changed.
• Set points for each device in increments of 16.
• The total number of internal user device points differs depending on the CPU module.
(
Page 334, Section 4.1 )
• The maximum number of points for bit devices is 32K.
For the internal relay and link relay, the number of points can be set up to 60K.
• For the timer (T), retentive timer (ST), or counter (C), one point includes one point of a word device and two
points of a bit device. ( Page 344, Section 4.2 (2))
Note 4.1
For the Universal model QCPU whose serial number (first five digits) is "10042" or later, the step relay (S) points can be
changed to 0K. ( Page 465, Appendix 2)
Note 4.2
This applies to the Universal model QCPU whose serial number (first five digits) is "10042" or later.
( Page 465, Appendix 2)
Note 4.3
For the Universal model QCPU whose serial number (first five digits) is "12052" or later, the points for the step relay (S)
can be set up to the following points in increments of 1K. ( Page 465, Appendix 2)
•Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU: 8192 points
•Universal model QCPU other than the Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU: 16384 points
Most of the default device
points can be changed.
