DPL01 Duplex Unit, which is used in a Duplex CPU Single I/O Expansion Sys-
tem, cannot be replaced. (The PLC will stop if a CS1D-DPL01 Duplex Unit is
replaced.)
The CPU Unit will operate in Simplex Mode while the Duplex Unit is being
replaced. If the active CPU Unit stops during replacement, the PLC will stop.
