Precautions
Refer to the operation manual for replacement procedures, and
observe the following precautions.
1) Turn OFF the power supply to all external devices connected to
the Unit before starting the replacement procedure.
2) Set the same unit number on the new Unit as was set on the Unit
being replaced.
3) When the new Unit has been mounted and the online replace-
ment operation has been completed for it, the settings stored in
the CPU Unit will be automatically transferred to the new Unit.
Refer to the Customizable Counter Unit operation manual for
replacement procedures, and observe the following precautions.
1) Turn OFF the power supply to all external devices connected to
the Unit before starting the replacement procedure.
2) Stop Unit operation before starting the replacement procedure.
3) Set the same unit number on the new Unit as was set on the Unit
being replaced.
4) When the new Unit has been mounted and the online replace-
ment operation has been completed for it, the settings stored in
the CPU Unit will be automatically transferred to the new Unit.
5) Use one of the following methods to transfer the same data to the
flash memory in the Special I/O Unit as was in the Unit that was
replaced: a) Use the simple backup function or b) Transfer the
user program and required data from the CX-Programmer.
Note The version 1 (-V1) Customizable Counter Units support a
simple backup function. If the data stored in the flash memory
in the Unit is saved to a Memory Card in advance and the
Memory Card is inserted into the CPU Unit, the Memory Card
can be used after online replacement to automatically transfer
the required data to the new Unit. (See note 1 following next
table.)
Pre-V1 versions of the Units do not support the simple backup
operation. Use the CX-Programmer to either transfer the
required data or set it again to the same settings as the Unit
being replaced. (See note 2 following next table.)
Refer to the High-speed Counter Unit operation manual for replace-
ment procedures, and observe the following precautions.
1) Turn OFF the power supply to all external devices connected to
the Unit before starting the replacement procedure.
2) Set the same unit number on the new Unit as was set on the Unit
being replaced.
3) When the new Unit has been mounted and the online replace-
ment operation has been completed for it, the settings stored in
the CPU Unit will be automatically transferred to the new Unit.
Note If the gate open operation is being performed with bit opera-
tions for the following bits, turn the bits ON after completing
online replacement so that the bits are effective: Bit 00 of
CIO n+2, Bit 00 of CIO n+5, Bit 00 of CIO n+8, and Bit 00 of
CIO n+11.
