Example
Maintenance Start Bit (A80015)
When the Unit Removal without a Programming Device function is selected
and a Unit is removed without a PLC Programming Device, one of the follow-
ing non-fatal errors will be generated depending on the type of Unit that was
removed. The PLC (CPU Unit) will not stop operating even if one of these
non-fatal errors occurs.
The Maintenance Start Bit is provided to prevent a non-fatal error from occur-
ring even if a Unit is removed without a Programming Device.
When you don't want a non-fatal error to be generated, turn this bit ON before
removing the Unit.
This bit can be turned ON externally (just like the Online Replacement Com-
pleted Bit) by allocating the bit to an external switch on an Input Unit and
inputting the signal or turning ON the bit from a PT. (The bit can also be
turned ON from the CX-Programmer or a Programming Console.)
der program or other source. As long as the Maintenance Start Bit is ON,
errors will not be generated even if there are Unit malfunctions, so the system
may be adversely affected.

Device is enabled.

Program example
vice (CX-Programmer or a Programming Console), always confirm that the
Unit Removal without a Programming Device or Removal/Addition of Units
without a Programming Device function has been enabled in the PLC Set-
up. If a Unit is mistakenly removed without enabling the function in the PLC
Setup, an I/O bus error will occur and the PLC (CPU Unit) will stop operat-
ing.
When this function is enabled in the PLC Setup, the Unit Replacement
without a Programming Device Enabled Flag (A09911) will be ON. This
flag can be used to confirm that the required PLC Setup setting has been
made.
