10.2 Firmware update
Introduction
During operation, it may become necessary to update the firmware (e.g. for function
extensions).
Firmware updates are used to update the firmware of the I/O device.
NOTE
Temporary bus interruption
When you update the firmware of an ET 200eco PN M12‑L I/O device, then the MultiFieldbus
is briefly interrupted due to the reboot of the I/O device. This interruption generates an alarm
in the controller for all downstream MultiFieldbus devices.
