SMC Corp. of America, is now offering ControlNet and CANopen compatible network adaptors on Series SV and VQC solenoid valves/manifolds. The ControlNet and CANopen serial communication protocol offering from SMC complements, previously released, DeviceNet, Profibus-DP, CC-Link an As-i protocols. The IP67 (Non-IP65/IP67 for ControlNet) compliant network adopter series EX250 integrates with SV and VQC manifolds and discrete input /output modules in one package. It has been designed for use in industries including automotive, food and beverage, water treatment, material handling, packaging, electronics and chemical processing. The EX250 serial network adaptor has been designed to reduce the need for wiring between conventional serial interface units and valves installed in confined spaces. The integrated assembly of the unit comprises a serial network adaptor and a user defined number of solenoid valves mounted on a manifold. The unit can drive 32 (24 for VQC) solenoid valve outputs and 32 sensor inputs, and is UL/CSA/CE compliant. The EX250 network adaptor is fitted with advanced self-diagnostics function that include monitoring of solenoid valve voltage and sensor power supply over current cut-off, with status information sent to master PLC.
