I checked the trafficLight Example, in DNS, in found some vairiable and values,
such as :
SCADA_PedRequests:sfp[pedrequests]
SCADA_Enable: sfp[enable]
SCADA_PedRequestPending:sfp[pedrequestpending]

...
so where does sfp come from? and also the key in sfp list?

sfp stands for Eclipse NeoScada's smal footprint protocol. An experimetn that we conducted once. This protocol is in the meantime deprecated and will no longer be maintained in 4diac FORTE. With on e of the next releases it will be removed. When we finally find tome to clean-up these examples these communication poitns would be moved to OPC UA.
