InstantHMI provides connectivity over various communication links: wired serial or Ethernet, or wireless infrared, WiFi, and Bluetooth. Communication protocols such as EtherNet/IP, TCP/IP, ActiveX and OPC are supported. Comm Drivers are available to support many communication protocols. Serial (RS-232, RS-422 and RS-485) links are supported. TCP/IP is a network communication protocol that allows nodes (computers and other devices) on an Ethernet network to exchange information among them. TCP/IP can be used in a LAN (Local Area Network) or through the Internet. InstantHMI implements TCP/IP, which allows the transfer of data between InstantHMI nodes (PC, PDA or Windows CE) across the room or across the world. EtherNet/IP is an 'Encapsulation Protocol' which carries forward the flavor of TCP/IP (and UDP/IP) very well. The EIP encapsulated message packet transmitted over the Ethernet media is embedded in a TCP/IP packet. EtherNet/IP implementation in InstantHMI enables access to AB Logix controller tags without requiring ladder logic change. Data access includes Class and Object Attributes thus simplifying and streamlining HMI functions across your entire industrial network. Access to Legacy Controller Files (PLC5e, SLC5/05, MicroLogix etc) is supported. ActiveX controls inherit much of their design from OLE documents, which allow applications to embed their data transparently in other applications. ActiveX Controls are COM objects with an User Interface. The InstantHMI Screen Designer and PC Runtime Engine are ActiveX containers. The Screen Designer as a container will allow you to insert ActiveX Control objects into the screen document. OPC (OLE for Process Control) is a standard OLE/COM interface communication protocol that allows OPC Servers and OPC Clients to exchange information relevant to field devices, and process controllers. InstantHMI implements OPC Client Data Access to OPC Servers. Bluetooth technology is built into many PDAs and provides RF (Radio Frequency) communications in the 2.45 GHz spectrum ...
