8.2 Data Storage
The Data Storage feature brings major advantages when it comes to easy replacement
of IO-Link devices due to defects. This means that the whole parameter set of the
device, e.g. switching point, additional logic or teach-in settings, are stored centralized
in the SIG200. In case a connection with a compatible device is established, this stored
parameter set is written to the device and it behaves like the device to be replaced.
There are two different use cases how to utilize this mechanism:
Use Case Backup + Restore:
Parameters are read and written in both directions, from the IO-Link master to the
device and vice versa. This mode is mostly used for commissioning meaning changes in
the device configuration for example triggered by a teach-in are automatically uploaded
and stored in the data storage object within the SIG200. It supports also device
replacement, e.g. the configuration will be automatically copied to the new device, if
one needs to be exchanged.
Use Case Restore:
In this mode the configuration of the connected IO-Link device will be stored and frozen.
It cannot be changed by the device, e.g. a teach-in directly at the device will be ignored.
Replacement of broken devices is also possible.
In any case this mechanism is only working when the devices are compatible to each
other. Therefore, it is necessary to set also the Expected Device and Vendor ID.
8.2.1 Example Usage
The SIG200 IO-Link Master Data Storage functionality allows straightforward replace‐
ment of failed IO-Link sensors. The following step-by-step example shows how the
SIG200 can be used to commission a new IO-Link device so that a replacement device
will be automatically reconfigured to match the original device.
1. Configure the IO-Link port of the SIG200 with an IODD file and with the Data Stor‐
age set to Disabled.
2. Configure the IO-Link device. The IO-Link device can now be configured using the
IODD View in the Configuration window IO-Link Devices tab or other configuration
mechanism such as with the IO-Link device’s teach button.
3. Change the Data Storage mode from Disabled to Restore. The SIG200 automati‐
cally uploads the new configuration.
4. Replace the original IO-Link device with a second device of the same type. The
configuration parameters from the first device are automatically loaded into the
second IO-Link device.
