Input Specifications
Special I/O Unit Area in CIO
Area (CIO 2000 to CIO 2959,
CIO 2000.00 to CIO 2959.15)
Regularly exchanges 10 words per Unit.

Universal Input Unit)
Special I/O Unit words in DM
Area (D20000 to D29599)
Transfers 100 words of data per Unit. The
following data is transferred at the indi-
cated time.
• Initial settings data: Transferred when
power is turned ON or the Unit is
restarted.
• Continuously refreshed data (e.g., alarm
settings): Transferred during I/O refresh
period.
• Expansion Setting Area: Transferred
during the I/O refresh period.
