3.8 Updating firmware
To update the firmware, the easyE4 expansion device must be connected to the base
device with the plug connector.
The number of the easyE4 expansion is determined based on the position after the
base devices in the assembly block, starting with 1 from the left. The maximum num-
ber 11 can be assigned to an expansion in the block.
An update must be carried out separately for each expansion device.
