Driver Overview
This is a list of industrial protocols supported by PlantPulse Edge. There are 44 types based on product specifications opc_type (43 drivers + 1 alias).
Each driver is implemented in the plantpulse.driver.protocol.<proto> package within plantpulse-edge-driver.jar, and ProtocolDriverFactory.createDriver(opc_type) creates an instance by referencing the APP_OPC.OPC_TYPE string.
Implementation Categories
- In-house Java Implementation (Majority) — Protocol framing is written directly on top of pure Java sockets. There are no external native or JNI dependencies. As of 2026-07, the Modbus family, PROFINET, AB-ETH, BACnet, KNXnet, and CANopen were rewritten as native, completely removing the Apache PLC4X dependency.
- External Libraries — MELSEC and S7 use
iot-communication, while OPC UA uses Eclipse Milo. - Native Bridge — For FOCAS, a C++ collector is launched as a child process and read via TCP/JSON.
- 4 Types of Stubs — CC-Link IE, DALI, IO-Link, and DeltaV. These guide configurations where a gateway bridges to a higher-level protocol rather than reading directly. The determination criterion is whether it inherits from
AbstractStubDriver.
Write support varies by driver
The Write column in the table below is the authoritative source. Attempts to write to drivers that do not support writing will be rejected.
