Duplex CPU Units
The underlined errors are related to duplex operation.
Operation switching errors
• CPU error
• Memory error

• Program error
• Cycle time overrun error
• FALS error
Fatal errors
• I/O bus error
• Duplication error
• Too many I/O points error
• I/O setting error

times are longer than for the CS1-H. (For details on processing time, refer
to 9-5 Instruction Execution Times and Number of Steps.
Synchronized instructions:
IORF(097) (I/O REFRESH), DLINK(226) (CPU BUS UNIT I/O
REFRESH), IORD(222) (INTELLIGENT I/O READ), IOWR(223) (INTEL-
LIGENT I/O WRITE), PID(190) (PID), RXD(235) (RECEIVE),
FREAD(700) (READ DATA FILE), and FWRIT(701) (WRITE DATA FILE)
the above instructions are executed (except for PID), the ER Flag will turn
ON. If that occurs, execute the instruction again.
