Intelligent PLC module with CAN/Ethernet bridge CAN/Ethernet bridge 16 digital inputs/outputs, individual configuration The PU 104 is part of the P-open series and provides compact PLC functions for automation applications requiring distributed intelligence. It also combines CAN with Ethernet, enabling Ethernet PCs to access CAN field busses directly, without an additional CAN interface. Apart from real-time processing, the unit features 16 on-board digital inputs, and 16 digital individually as inputs or outputs. purposes, the PU 104 is fitted with a complete CAN/CAN master/slave implementation, plus a CANopen master implementation as a library for With its compact dimensions of 124 x PU 104 is ideally suited for mounting close to the process in de-centralized The housing is designed for clip-on mounting to standard DIN rails. System extensions are easily implemented by connecting additional I/O modules to with cables which plug into the module's extension bus (E-bus).The resulting complete PLC system is linked provided via two terminals at the signal level. The supply voltage is 24VDC. The l/O's can be divided into 6 groups, each with its own supply. This enables disabled by means of an external switching device. Convenient field connections Electrical wiring from the machine or process is taken directly to the terminal modules. The terminal strips are of the plug-in type, allowing system pre-wiring as well as fast module Furthermore, the following alternatives are available for the terminal strips: • Screw terminals • Screwless spring-clamp terminals • Crimp terminals. Inputs/outputs are connected using the 3-wire principle. Front panel LEDs indicate the signal status of every I/O, and the module's operational status. The LED positions are directly asso- ciated with the corresponding l/O's. Inscription labels on the terminal strips allow clear identification of each I/O. CAN/Ethernet bridge Together with its PLC functions, the PU 104 provides a ..bridge" between CAN-CALand Ethernet TCP/IP networks. For linking into the Ethernet, applications and Ethernet network modules, have direct access to CAN fieldbus networks.The bridge function is supported by an ANSI-C library in the Programming with standard tools The universal programming tool is used for all of PMAs P-open modules. Depending on your application, the programming software lets you choose the most convenient method: Instruction List (IL), Ladder Diagram (LD), Function Block Diagram (FBD), or the high-level language'C. The first three options are according to the If necessary, we provide full support during development of your own application-specific programs.
