Fieldbus remote I/O module ASCON

The Ascon’s deltadue offers several modules for I/Os, control and acquisition. Connectivity is guaranteed by MODBUS RTU serial comms and by gateways, line adapters, line converters, WebSCADA and Managers which allow to realize different architectures by connecting the modules to:

o A PLC or SCADA with MODBUS TCP via an Ethernet network or the web

o Any web browser for the configuration of HTML management pages and to MODBUS TCP SCADAs via an Ethernet network

o A MODBUS TCP SCADA (via an Ethernet network) and to a PLC (PROFIBUS DP or MODBUS RTU or DeviceNet) simultaneously

o CANopen, PROFIBUS DP, DeviceNet networks

o MODBUS RTU networks with different baud rate, parity and stop bits

o Two masters, such as Operator Panels, SCADA, PACs, simultaneously

The series include: universal analogical inputs (Pt100, T/C, mA, mV), digital inputs; universal control outputs (mA, relay, SSR), PID algorithm with overshoot control; heat/cool PID. The Manager provides: automatic learning and back-up of the configuration data of the modules; Hot Swapping to maximize process uptime; automatic configuration of replaced modules; the other modules work while replacing the failed module to reduce machine downtime; offline configuration to simplify start-up, when the modules are inserted, they are recognised, configured and parameters are downloaded; diagnostic, scanning of the connected modules to verify if they are the correct ones and if they work properly, actions can be taken quickly. Modules work as independent units; no backplanes or common modules are necessary. The Manager and the Gateways are needed only when their functions are necessary
