12 GX Configurator-PN
(c) 2013 MITSUBISHI ELECTRIC CORPORATION
PROFINET firmware.
If the IO-controller is starting or
started, each connection will
be automatically released by
the firmware, even if the
connection is in manual mana-
gement.
firmware.
If the IO-controller is stopping
(stop sequence), the firmware
will continue the stop se-
quence up to the end and then
will initiate again a start se-
quence.
If the IO-controller is stopped,
the IO-controller will be started.
The controller will try to start
each connection with an IO-de-
vice, which is configured with
automatic management mode
(1). Each connection with a de-
vice in manual management
mode will not be up until the
PLC explicitly sends a com-
mand to the device.
(1) See IOD_MGT_MODE registers. By default the IO-device management is in automatic mode
(bits are 0). If the PLC does nothing, every connection will automatically be started, when the IO-
controller is started.
IOD_MGT_MODE Registers
With these 128 bits the PLC can indicate, how each connection to an IO-device should be managed
by the firmware.
- for an IO-device in automatic mode the IO-controller will initiate the connection, until the connecti-
on is established.
- for an IO-device in manual mode the IO-controller will wait for commands from the PLC to manage
the connection (see IOD_START_STOP and IOD_CMD_HSK_Y registers).
