The SpiderControl SCADA Server is also available on Linux. It can import all symbolic variables directly from the WAGO PLC! This is based on the SDB file generated by CODESYS, which is also stored on the PLC. The SpiderControl SCADA Server has a freely programmable DB interface. PHP scripts can be used to create arbitrary DB queries. The queried variables are freely usable in the namespace of the Web visualization and can be used with all Visu elements.
