POINT
For the High Performance model QCPU, Process CPU and Redundant CPU, the
total number of internal relay, latch relay, annunciator, edge relay, link relay, link
special relay, step relay, timer, retentive timer and counter points is a maximum of
64k points.
(3) Memory capacity
Use the following expression to obtain the memory capacity of an internal user device.
(For the Basic model QCPU)
(Bit device capacity) + (Word device capacity) + (Timer, retentive timer and
counter capacity) 16.4k words
(For the High Performance model QCPU, Process CPU, Redundant CPU)
(Bit devices capacity) + (Word devices capacity) + (Timer, retentive timer and
counter capacity) 29k
(a) For bit devices:
For bit devices, 16 points are calculated as 1 word.
(b) For timer (T) retentive timer (ST), and Counter (C):
For the timer, retentive timer, and counter, 16 points are calculated as 18 words.
(c) For word devices:
For data registers (D) and link registers (W), 16 points are calculated as 16 words.
POINT
When an internal user device's "number of usable points" setting is changed, the
following files which were created under the previous setting cannot be used as
they are.
• The sequence program
• The SFC program
• ST program
When the number of used internal user device points is changed, read the above
program from the CPU module to GX Developer, and write it to the CPU module
again.
