I work with PascalSCADA 0.7.5.0 from OPM.
Access with the TTCP_UDPPort, TISOTCPDriver and TPLCTagNumber works for Flags (german: 'Merker') works without a problem. (Memreadfunc, Memwritefunc = 3, MemAdress = FlagAdress, PLCRack = 0, PLCSlot = 2, TagType = pttWord).
If i want to access DB 200:DBW2 it doesnt work and return and io??? Error ( I have no PLC actual for tests)
(Memreadfunc, Memwritefunc = 4, MemAdress = 2,Mem_FileDB=200, PLCRack = 0, PLCSlot = 2, TagType = pttWord).
Have i forgotten/misconfigured something ?
Attached a minimal Demo Project.
It uses the Packages pascaslscada (OPM), pascalscada_hmi (OPM) and RuntimeTypeInfoControls
