Man-machine interface and PLC in the use of vacuum forming machine
Intense competition in the market economy today, the system of the refrigerator interior to cook each have their own characteristics, for our products will give you more convenience, you greatly increase production efficiency.
In the refrigerator production line equipment, single station vacuum forming machine system uses a very popular model for each refrigerator must be of a different process parameters and mold adjustment, with the localization of PLC and continue to lower costs, PLC in energy-efficient industrial production lines and improve production efficiency and other main surface to play an increasingly important role.
For single-station vacuum forming machine control system work environment and energy conservation, efficiency requires the use of the PLC whims and fast response, easy to operate. So we launched the Siemens S7-200 series PLC and Wei Lun provided through MT-500 series touch screen composed of a single-station vacuum forming machine can complete the above industry requirements.
Siemens S7-200 series PLC to a very high reliability and low cost for industrial production site controller of choice. It can adapt to on-site environmental electromagnetic interference and high temperature, high humidity applications.
Siemens CPU226 core of the system as a module, then add O / I expansion module EM223, EM222, and the analog input module EM231, EM232 component output module; to complete the Automatic, Manual and adjusting the three operating states for the operator to bring a great convenience.
CPU226 module has two RS485 interfaces, point to point interface (PPI) multipoint interface (MPI) PROFIBUS very convenient in the use of a touch screen can be used for the control, and other companies that can be used for communication between modules.
Human-computer interface using touch screen is simple and reliable, especially for the complex environment of health of industrial field use. Siemens PPI specific communication protocol uses RS485 communication lines and reliable communication distance up to 50 meters.

What is PCI Interface?
A CPU module (http://www.tri-m.com/products/evalue/esm2615.html) with future expansion PCI interface, what does it mean?Does it mean I can use this interface for my proposed wireless 802.11b/g LAN?
PCI = Peripheral Component Interconnect. It's one of the standards for connecting peripherals (such as network cards, video cards, etc.) to a PC's motherboard.
See here for an article and pictures; http://en.wikipedia.org/wiki/Pci
If you want to use your PC with a wireless LAN, then you will need to purchase a wireless LAN card. The card will likely use the PCI standard. However, PCI by itself does not give you access to a network (wireless or otherwise).
After looking at the spec sheet for the device you link to in your question, it looks like an add-on module for a specific type of system.....It's something you typically don't add to a system unless you already knew what you were needing it for....and it really doesn't go with a PC. It goes with a specific type of carrier board.
If you don't know what PCI is, I'm guessing you don't know what this device is designed for.
