5.2 Internal User Devices
Set the internal user devices within 29K words in total. One point of the timer, retentive timer, and counter is
regarded as one word device point and two bit device points.
(Bit device) + (Timer, retentive timer, and counter) + (Word device) ≤ 29K words
• For bit devices, 16 points are calculated as one word.
• For the timer, retentive timer, and counter, 16 points are calculated as 18 words.
• For word devices, 16 points are calculated as 16 words.
If the points for the internal user devices are changed, the programs created with the previous parameters can no longer be
used. Read the program files from a programming tool, and then write them back again to the CPU module.
