Local information exchange in the plant network

The external IO-Link memory DSU is a mobile all-purpose device for local data transmission. Connected to an IO-Link master, the small device makes the stored data available to all connected receivers. For example, if used as a digital type label for an interchangeable tool, the PLC can identify it independently and reliably, extract information about operating hours and alert the operator when maintenance is due to prevent damage to the tool or workpiece. During operation, the data is continuously written to the historical memory. Thanks to the COM3 interface with 230.4 kbit/s per second. A total of 128 kBytes offer enough space for all relevant data.

Configuration and reading of data via moneo|configure

The IO-Link memory can also be parameterised and read via the IoT software moneo|configure In this way, recorded data of total operating hours, maintenance intervals or system-relevant maximum and minimum values such as pressure, temperature or vibration data, can be easily read. An optional write protection protects against accidental overwriting of sensitive device information.

Description of the technology

The DSU100 is a 128 kBytes FRAM data carrier which serves as a storage medium in industrial environments. Parameter setting and data exchange take place via the integrated IO-Link interface and can be carried out, for example, via the moneo|configure software while the system is not in operation.

Device-specific information

The IODD required for the configuration of the unit, detailed information about process data structure, diagnostic information, parameter addresses and the necessary information about the required IO-Link hardware and software can be found on the website.

Operating modes of the device

The device supports various operating modes, such as reading the device-specific globally unique UID, reading and writing up to 28 bytes of data in one IO-Link cycle and reading and writing larger amounts of data, with length restrictions usually only imposed by the PLC. Automatic access to the memory stick during operation can be defined via numerous commands that regulate and control the read and write access.
