This page is the central starting point for connecting AMiT controllers to Mervis SCADA. AMiT PLCs can communicate with Mervis in two ways, depending on the age of your controller and firmware:
If you are unsure which method applies to your controller, contact AMiT technical support or Mervis technical support.
Newer AMiT controllers offer native support for Mervis CloudAccess, using AMiT's own WebSocket protocol directly in the controller. This removes the need for a separate proxy tunnel — the PLC connects directly to the CloudAccess cloud service, and the Mervis SCADA project is generated from a WebSocket mapping file.
AmitWebSocketUtil.exe to generate an XLSX mapping file directly from the project uploaded to the PLC.For the full step-by-step procedure, download links, and example generator parameters, see: Amit WebSocket - Integration.
For older AMiT controllers, communication is handled through the Mervis Proxy Service using the DB-Net/IP protocol. This method requires configuring a ProxyID, password, and proxy server address on the controller, and using the AtouchProxy helper application for third-party tools (DetStudio, ViewDet) that don't support Mervis Proxy natively.
For full configuration details — including server addresses, ports, ProxyID/password setup, application code examples, and AtouchProxy — see: Amit DB-Net/IP - AmitProxy.
| Method | Best for | Requires |
|---|---|---|
| AMiT WebSocket + CloudAccess | Newer controllers, new installations | DetStudio 3.2.12+, CloudAccess configuration |
| DB-Net/IP + AmitProxy | Older controllers, existing DB-Net installations | ProxyID/password, AtouchProxy (for legacy tools) |
