3 Configuration Software
 Action to PLC Mode Transition Box
The Action to PLC Mode Transition Box defines the behavior of the Unit on the PROFIBUS network,
in case a CPU mode change occurs. The check boxes define how the Unit should behave in case
the CPU mode is changed from RUN mode to PROGRAM mode, or vice versa. Refer to section 1-1-
7 Network Operation Modes for more information on PROFIBUS operational modes.
 Change CPU to RUN Mode
The table below defines the behavior in case the CPU changes to RUN mode.

 Change CPU to PROGRAM Mode
The table below defines the behavior in case the CPU changes to PROGRAM mode.

 Auto-CLEAR Box
Auto-CLEAR defines the Unit's behavior in case an error occurs in one of the allocated slave
devices, which causes it to stop data exchange with the Master Unit. If Auto-CLEAR is enabled, the
Unit will automatically transition to the CLEAR state and force all its allocated slave devices to the
'safe' state, i.e. all outputs are set to 0, using the Global-Control CLEAR command.

 Support Box
The Auto Addressing in the Support Box defines the I/O Mapping process when adding/removing
I/O modules or when editing an existing I/O Mapping. Refer to section 5-5-2 Mapping I/O Data for
more details on I/O mapping.

Description
Unit keeps the current mode if the CPU goes to RUN mode (e.g. stay in
CLEAR mode).
The Unit goes to the OPERATE mode whenever the CPU goes to the RUN
mode.
Description
Unit keeps the current mode if the CPU goes to PROGRAM modem (e.g.
stay in OPERATE mode).
The Unit goes to the CLEAR mode whenever the CPU goes to the PRO-
GRAM mode.
Description
Selected Unit transitions to the CLEAR mode in the event of a network error,
e.g. because one or more configured slaves are not in the Data Exchange
mode.
Selected Unit does not transition to CLEAR mode, but attempts to re-param-
eterize the slave device.
Description
I/O data mapping will be done by the Master DTM by allocating the I/O data
in ascending order of slave device address and selected I/O modules. No
memory allocation gaps are left behind.
New I/O modules are appended to the existing mapping. Changed I/O mod-
ules will be re-allocated to the end of the list. Memory allocation gaps can be
left behind.
