The SIMATIC Touch Panel (TP), Operator Panel (OP), Basic Panel, Comfort Panel, Mobile Panel, multifunctional platforms (MP)1) offer HMI functionality for the control systems:
- SIMATIC S7
- Non-Siemens controllers:
- Allen Bradley
- Mitsubishi
- Modicon
- Omron
For more detailed information, refer to the WinCC (TIA Portal) user manual, the “Windows-based systems communication” manual, or the WinCC (TIA Portal) online help.
OPC communication and HTTP communication are offered for all Panels with an integrated Ethernet interface. Both OPC and HTTP communication can be used in parallel with the process links to SIMATIC S7 or non-Siemens PLCs.
1) For the sake of simplicity, SIMATIC Panel is always used in the text below. This is not restrictive, as the information is valid for all systems referred to above. If there are constraints, direct reference is made to them in the text.
Note:
Interface options for HMI devices: See the individual device descriptions.
OPC communication
OPC Data Access is an open standard for exchanging both local and remote variables between various applications via Industrial Ethernet. The original version of OPC is based on Microsoft COM/DCOM and, therefore, requires a Microsoft Windows-based PC operating system (not Windows CE) on both clients and servers. As OPC XML, communication is based on the Internet standard SOAP/XML and is, therefore, suitable for embedded systems with Windows CE.
HTTP communication for variable exchange between SIMATIC HMI systems
Communication based on HTTP message frames enables variables to be exchanged between SIMATIC HMI systems.
