Automation controller with variable I/Os

The WP-9000-CE7 is a Windows CE 7.0 based PAC (programmable automation controller) of ICP DAS. CAN devices can be integrated via a CAN communication module.

Each WP-9000-CE7 is equipped with a Cortex-A8 (1,0 GHz) CPU that runs the Windows CE 7.0 operating system. They also feature a variety of I/O ports (VGA, USB, Ethernet, EIA-232/485). There are 2, 4, or 8 slot options provided to expand the local I/Os. The I/O modules can be parallel bus type (I-9K series) or serial bus type (I-97K series) I/O modules. Modules are provided for AI, AO, DI, AO, counter input, frequency input, PWM output, motion control, memory, communication, etc.

With a CAN communication module in the local slot, CAN devices are easy to integrate, said the company. A built-in VGA port can be directly connected to a regular LCD display. Users can operate the HMI or Scada software (running on the PAC) with display, keyboard, and mouse just like on regular PCs. The 64-bit hardware serial number is unique and individual.

According to the company, the controller’s operating system, Windows CE 7.0, offers advantages, including real-time capability, small core size, fast boot speed, interrupt handling at a deeper level, achievable deterministic control, and low cost. Using Windows CE 7.0 in the WP-9000-CE7 gives it the ability to run PC-based control software such as Visual Basic.NET, Visual C#, Visual C++, Scada software, and Soft PLC.

A system can crash if the OS or the AP fails. Two watchdogs (OS watchdog and AP watchdog) were designed to automatically reset the CPU when this happens. To prevent the PAC from failing because of a power loss, the power module is designed with two inputs. The PAC can keep working even if one power input fails and meanwhile a relay output reports the power failure. Each product is housed in a plastic-based box with a column-like ventilator that can help to cool the working environment inside the box and allow it operating between -25 °C and +75 °C.
