Module 1 cổng DeviceNet Master ICP DAS I-9124 CR

CAN (Controller Area Network) is a serial communication protocol that supports distributed real-time control and has high security features. CAN is particularly suitable for networked “intelligent” devices and systems, or sensors and actuators in subsystems. In a CAN network, generally, there is no addressing of users or stations, but rather the sending of priority messages.

I-9124 is a DeviceNet master module that supports both Group 2 and UCMM functions, offering a high-performance DeviceNet master solution. Combined with the expansibility and flexibility of the WinPAC-9000-CE7 series host, I-9124 can be used in applications with higher real-time requirements. I-9124’s firmware includes a complete set of DeviceNet communication protocol encoding and decoding functions. Application developers can use simple “Read” or “Write” commands to control the I/O data of remote DeviceNet slave devices. Thus, I-9124 not only expands the WinPAC-9000-CE7 series host with a DeviceNet communication interface but also assists users in efficiently monitoring remote DeviceNet slave devices without being familiar with the complex DeviceNet communication protocols.

There exist two memory areas, “Input Area” and “Output Area”. The input data of all DeviceNet slaves would be stored in the “Input Area” by DeviceNet master scan engine. Oppositely, the output data of those DeviceNet slaves would be in the “Output Area”. Please refer to the following figure.

Users can read a bulk data from “Input Area” in the DeviceNet Master module, like PISO-DNM100U or I-8124W. This bulk data contains multiple devices’ input statuses. If one of the input status of the remote DeviceNet slave changes, the corresponding data located in the “Input Area” would change immediately. Oppositely, the “Output Area” contains multiple devices’ output data. Users may change the output value of a certain device by changing the corresponding data located in the “Output Area”.
