The CPX I/O system is a line of Ethernet-enabled highly modular IP65 valve manifolds. Protocols include Ethernet/IP, Modbus TCP, standard IT protocols, and further industrial protocols in preparation. The system also accommodates IT protocols for supporting e-mail, file transfer, integrated Web servers, and communications for OPC, DDE, and others. An embedded controller enables decentralized or stand-alone control. Complete diagnostics via LED, network, or handheld, provide fast error detection for easy service. An optional CPX-MMI handheld device provides clear descriptive diagnostic and commissioning messages. The units reduce labor costs by up to 70 percent, according to the company, with easy installation, exchange, service, or expansion of I/O modules, manifold bases, and valves. Flexible electrical connections include multi-pin or Fieldbus, full diagnostics, mixed valve sizes, and multiple pressure zones on a single manifold. Designed to ISO standard 15407-2, the units have a flow rate per valve up to 1,000 l/min. Up to 32 solenoids with a full range of pneumatic accessories are available. Flow rate per valve is up to 700 l/min.
