Hardware Features
Powerful CPU Module
The most important features of the CPU module are
- Cortex-A8 (1.0 GHz)
- 512 MB SDRAM (DDR3)
Built-in VGA Port
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 WP-9000-CE7) with display, keyboard and mouse just as how they usually did on regular PCs.
64-bit Hardware Serial Number
The 64-bit hardware serial number is unique and individual. Every serial number of WP-9000-CE7 PAC is different. Users can add a checking mechanism to their AP to prevent software from pirating.
Rich I/O Expansion Ability (RS-232/485, Ethernet, FRnet, CAN)
Beside the local I/O slots, WP-9000-CE7 also equips several RS-232/485 ports, two Ethernet ports to connect serial I/O and Ethernet I/O. And with FRnet and CAN communication module in local slot, FRnet I/O and CAN devices are easy to be integrated.
Dual Watchdog Timer
A system could be hanged up when the OS or the AP fails. There are two watchdogs (OS watchdog and AP watchdog) designed to automatically reset the CPU when the situations happen. The design will increase the reliability of the system.
Dual Ethernet Ports
WP-9000-CE7 provides two Gigabit Ethernet ports. The two Ethernet ports can be used to implement redundant Ethernet communication and separate Ethernet communication (one for global Internet, one for private Ethernet).
Rugged RJ-45 connector for LAN1
The WP-9000-CE7 is equipped with a rugged and dustproof RJ-45 connector on the LAN1 port that is able to provide protection against both liquid and dust contaminants in harsh industrial environments, as well as protection against vibration and shock.
Power/Communication Spring Clamp Terminal Connector
The spring clamp terminal block that is used for the Power/Communication connector in the WP-9000-CE7 offers advantages including anti-vibration, stable clamping, and easier installation.
Metal Enclosure
The WP-9000-CE7 features a durable metal casing to provide high levels of impact resistance and flame resistance, and higher protection on EMS or other electromagnetic noises.
Redundant Power Inputs
To prevent the WP-9000-CE7 from failing by the power loss, the power module is designed with two inputs. The WP-9000-CE7 can keep working even one power input fails, and mean while there is a relay output for informing the power failure.
Ventilated Housing Design Allows Operation Between -25°C ~ +75°C
Each WP-9000-CE7 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 the WP-9000-CE7 operating between -25°C and +75°C.
Standard WP-9000-CE7 (Windows Compact Embedded 7.0 Inside)
The controller supports following software development tools:
1. DLLs of I/O modules for VC, VS.Net 2008
2. DLLs of Modbus/RTU and Modbus/TCP for VC and VS.Net 2008

Local I/O Expansion
I-9K and I-97K series modules are provided for combining a variety of I/O functions within the WP-9000, XP-9000, LX-9000 and LP-9000 programmable automation controllers (PAC). The I-9k series is based on a parallel interface with high communication speed; while the I-97K series is based on a serial interface.
The differences between the two series are listed as follows:
| Model | I-9K Series | I-97K Series |
|---|---|---|
| Communication Interface | Parallel Bus | Serial Bus |
| Protocol | - | DCON |
| Communication Speed | Fast | Slow |
| DI with Latched Function | - | Yes |
| DI with Counter Input | - | Yes (100 Hz) |
| Power on Value | Yes | Yes |
| Safe Value | Yes | Yes |
| Programmable Slew-Rate for AO Module | - | Yes |

Remote I/O Expansion
Ethernet
The available Ethernet I/O devices are ET-7000, ET-7200, ET-87P4/8-MTCP and I-8KE4/8-MTCP. The PAC can access them in Modbus/TCP protocol. A nModbus.dll is provided for C#, VB.net programming.
RS-485
The PACs are equipped with the RS485 COM ports which enable the transmission rate up to a maximum of 115.2 Kbps. The medium for connection is a twisted-pair, multi-drop, 2-wire RS-485 network that can link I-7000, M-7000, RU-87Pn with high profile I-87K modules. To access M-7000, a nModbus.dll is provided for C#, VB.net programming. To access I-7000 and RU-87Pn with high profile I-87K modules, PACSDK is provided for C#, VB.net, VC and VB programming.
FRnet
FRnet is an innovative industrial field bus that has many special features, such as high-speed deterministic I/O control, real I/O synchronization capabilities, non-protocol communication, and easy programming. With a FRnet communication module (I-8172W), the PAC can link FRnet I/O modules to implement high-speed distributed I/O (FR-2000 series). To access I-8172W, a pac_i8172w.dll is provided for C#, VB.net, VC and VB programming.
CAN Bus
The Controller Area Network (CAN) is a serial communication way, which efficiently supports distributed real-time control with a very high level of security. It provides the error-processing mechanisms and concepts of message priority. These features can improve the network reliability and transmission efficiency. Furthermore, CAN supplies the multi-master capabilities, and is especially suited for networking“intelligent” devices as well as sensors and actuators within a system or a sub-system. With I-8123, I-8124, I-87120, the PAC is able to demonstrate every feature of CAN, CANopen, and DeviceNet.
