4.2.2.2 Firmware activation
In general the module firmware can be activated by reset and restart of the EN100 – module.
Note:
Depending on the device firmware there are two different ways for activation required (please refer the table
in chapter 5.1).
•
After module FW upload and flashing the device has to be reset by power off or device restart.
Advantage
: This procedure is possible for all device firmware versions (no need to care about). This
procedure succeeds always. If a disabled protection for activation of the EN100-FW can be accepted, this
type of reset is the preferred method in the commissioning process.
Disadvantage
: All device functions (e.g. protection functions) are disabled during device reset.
•
The activation button at the module homepage can be used. In this case just the EN100 restarts.
Advantage
: The protection is available during module firmware activation.
Disadvantage
: Not for all device firmware versions applicable.
Attention:
The correct assignment of the process data objects has to be checked after module firmware
activation.
Background of the different required activation methods is the information synchronization between the device
firmware and the module firmware. With the table in chapter 5.1 you can check which devices includes the
necessary synchronization mechanisms and which one does not.
In general it is recommended always to activate the module firmware via device reset. So problems regarding
process data assignment are avoided from beginning on.
The Table in chapter 5.1 lists all software reset capable devices.
4.2.2.2.1 Activation via devices reset
1. Restart the device to activate the uploaded EN100 firmware.
Please note that the protection is disabled during the “Device Reset”. A password is required for
this operation.
This can be done in 3 different ways:
power off
the front display menu.
c) via
DIGSI 4
a.
Remove the power supply of the device via power off for about 20 seconds.
