描述:
SNAP PAC brains are compact, high-performance processors that connect real-world analog, digital, and serial devices with Ethernet or industrial RS-485 networks for monitoring, control and data acquisition. A SNAP PAC brain on a mounting rack with I/O modules is called an I/O unit. Each I/O unit can operate independently or as an intelligent, distributed node on a larger network controlled by a SNAP PAC controller. SNAP PAC brains are available for use on both Ethernet and RS-485/422 serial networks. SNAP PAC Brains for Ethernet Networks * The SNAP-PAC-EB1 Brain Works with Analog, Digital, and Serial Signals, and Supports High-Speed Digital Functions * The SNAP-PAC-EB2 Brain Works with Analog, Digital and Serial Signals * Use Intelligent SNAP I/O with Allen-Bradley? PLC Logix Systems Ethernet-based SNAP PAC brains feature pure TCP/IP transport protocol, two switched 10/100 Mbps Ethernet interfaces, and multiple simultaneous protocols such as Modbus/TCP, SNMP and SMTP.
