Modbus Plus Network
A multi-purpose networking solution combining high speed, peer-to-peer communication with easy installation
In computers with available PCI slots, Modbus Plus support may be provided using the PCI-85 Modbus Plus adapter. Increasingly, however, manufacturers are eliminating PCI slots from new computers and replacing them with faster and less expensive PCI Express slots. The newer PCIe (Peripheral Component Interconnect Express) technology offers a high-speed serial expansion bus standard designed to replace the older PCI, PCI-X and AGP bus standards. The new PCIe-85 is designed to provide Modbus Plus support on these computers.
Today's PCs are evolving toward the replacement of RS232 and other serial ports with several USB ports. Also, new PC notebooks no longer provide type-III PCMCIA slots. Consequently, connecting a PC directly to products such as PLCs, HMI or remote equipment through a Modbus Plus network becomes increasingly difficult or impossible, thus depriving a user of basic functions such as programming or debugging applications.Modbus Plus application
