Firmware Update

Only update firmware when the system is in a safe state!
Firmware updates must only be done when the system is in a safe state.
The system must be checked after a firmware update!
Before commissioning, the safety functions of the automation system must be
checked after changes have been made to the firmware. These tests are a
requirement for occupational safety!
Replace module if firmware defective!
If the module issues the diagnostic message "Firmware update required,"
updating the firmware again is only permissible if this message was issued due
to a previously aborted firmware update.
If the module reports this diagnostic after having functioned without errors, it
must be replaced.
Note firmware version!
Only firmware intended for the F I/O module can be loaded.
You can update firmware on the Series 750 I/O Modules with the software
"WAGO I/O-Update 750." The I/O modules can be updated via the service
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.
