The following steps must be performed in advance before replacing a Unit
online without a PLC Programming Device.
The Unit Removal without a Programming Device or Removal/Addition of
Units without a Programming Device function must be enabled in the PLC
Setup in order to remove a Unit without a PLC Programming Device.
Use a Programming Console to set the appropriate PLC Setup address.

Setup and a Special I/O Unit has been removed, the Special I/O Unit Area
words allocated to that Unit for data transfer (to and from the CPU Unit) will
be cleared. If the loss of the Special I/O Unit Area data will adversely affect
the system, disable the Unit Removal without a Programming Device or

function is enabled in the PLC Setup, the I/O bus error will be treated as a
non-fatal error and PLC (CPU Unit) will not stop operating. If there are any
Units that will adversely affect the system if an I/O bus error occurs, do not

Removal/Addition of Units without a Programming Device function can be
selected with the Programming Console only. The settings will be added to
the CX-Programmer in the next version upgrade. The settings will be add-
ed to CX-Programmer version 7.0 when its functions are expanded by
auto-update.
A Programming Device is not
required. A non-fatal Unit error
will occur in the Unit being
replaced.
