Firmware Update/Downgrade

You can update firmware on the Series 750 I/O Modules with the software

interface or, for ETHERNET-based fieldbuses, via the fieldbus connection on the
fieldbus coupler/controller.
Observe the following information:
Do Not Switch Off the I/O Module!
Interrupting the update process can damage the I/O module.
Do not remove the I/O module during the update process. Do not interrupt the
power supply!
• Ensure that communication with the fieldbus coupler/controller is not
interrupted during the update process.
• Any PLC application running on the controller must be stopped before the
update process.
• Before an update via the service interface, disconnect the fieldbus cable
from the fieldbus coupler/controller.
• Do not close the software during the update.
• Only run the software from a local hard disk.
