Virtual Fieldbus Simulator

EVA ICS Virtual Fieldbus Simulator is a pack of services which can simulate a virtual fieldbus on any EVA ICS v4 node.

The source code is available at https://github.com/eva-ics/sim

Currently Virtual Fieldbus Simulator supports simulation of Modbus and TwinCAT/ADS.

EVA ICS can combine both Virtual Fieldbus Simulator and SCADA services on the same machine, however there are no internal bus methods for SCADA services to directly synchronize data with the virtual fieldbus.

To connect to a virtual fieldbus, the standard services must be used (e.g. Modbus: Modbus master controller) as any software/hardware acts with virtual fieldbus as with a real one.

Certain virtual services may provide internal bus methods for fieldbus data visualization which can be accessed by EAPI commons applications/services or via HMI service as bus::<SVC>::<METHOD> HTTP API methods.
