Data Gateway

The Flexy is capable of publishing data through different communication protocols: OPC UA, Modbus and SNMP.

OPC UA server

The Flexy can act as an OPC UA server. This allows tags exposure (and so data) to 3rd-party applications that feature an OPC UA client (like SCADA), reporting software, ...

For each tag created, you can associate this tag to a group (A, B, C or D) which will be published by the Flexy (OPC UA server) to your OPC UA client.

The OPC UA client can then browse the tags list and thereafter read/write the value of the tags in OPC UA. This will, for example, allow a 3rd-party application to interact with the PLCs and meters, even if the application does not support the PLC protocol.

Modbus

The Flexy can act as Modbus TCP server. This allows tags exposure (and so data) to 3rd-party applications, like SCADA, IO servers, custom developments, ... For each tag created, you can associate it with a Modbus register.

The third party application can thereafter read/write the value of the tag using the Modbus TCP protocol.
This will, for example, allow a 3rd-party application to interact with the PLC, even if the application does not support the PLC protocol.

SNMP server

The Flexy can act as an SNMP server. This allows tags exposure (and so data) to 3rd-party applications using the SNMP protocol. For each tag created, you can associate it with a unique object identifier (OID).

The 3rd-party application can thereafter read/write the value of the tag using the OID. The Flexy can also execute SNMP TRAPs. These traps can be executed as alarm notification or using Basic script command sendtrap.
