01 / CAPABILITIES
One workspace.
Your entire workflow.
Load SCD, ICD and CID files, connect to real IEDs or simulate your own test environment.
MMS server simulator
Built-in IEC 61850 Edition 2.1 server (Class A/B). Load SCD, pick an IED, edit variable values, attach signal generators to any MX value. Conformance-test ready against UNIGRID SA. Waveforms: sine, triangle, sawtooth, square, ramp and random. Quality and timestamp are maintained automatically.
GOOSE & Sampled Values
The separate JCH GOOSE Bridge (standalone, free) handles the Layer-2 frame work (libpcap). Studio connects over WebSocket — Subscribe + Publish for GOOSE and SV.
SCL editor
Substations, Voltage Levels, Bays, IEDs, LDevices, LNs, DataSets, RCBs, GoCBs, Inputs. Export as SCD/ICD/IID/CID/SED. Three built-in demo projects for training and conformance testing. ConductingEquipment.
Spec-compliant SCL export
xsi:schemaLocation, RptEnabled, correct P-element ordering, transitive DataTypeTemplates closure. Compatible with Phoenix Engineer, Siemens DIGSI, ABB PCM600, openSCD.
Bilingual
Full support for German and English. App and website follow the system language or can be switched manually.
02 / JCH GOOSE BRIDGE
