Amplicon has introduced the ioLogik range of PLC-grade remote I/O servers, which have been developed by Moxa to offer higher performance and functionality than available alternatives. The range comprises two discrete I/O modules and the modular 4000 series, providing an easy-to-use networked I/O solution. The ioLogik E2210 remote server is designed to read and control the online status of up to 20 connected devices over an Ethernet network from a host computer. The E2240 supports eight analogue inputs and provides control of two analogue outputs. Both models are available with a plug-in display for programming and the reading of inputs and are easily expanded via the on-board RS485 interface. Active I/O messaging allows alarms to be sent over Ethernet, saving network bandwidth.
The ioLogik 4000 series is a modular system comprising either an Ethernet or serial adapter, and a variety of analogue and digital I/O modules. This allows users to choose the correct number and type of analogue and digital inputs or outputs to suit each application. Customers can choose from volts, mA or temperature inputs, volts or mA outputs, and a variety of different digital I/O modules. Up to 32 modules can be connected to an integral bus system, removing the need for a back plane. Isolation is provided when external voltages exceed 24Vdc. The RS485 serial adapter allows the 4000 series to be connected to either an E2210 or E2240 server for higher flexibility.
A comprehensive range of software tools are available to support the ioLogik range. These include Modbus/TCP and Modbus RTU drivers that allow integration with the most popular SCADA software packages. There is a DLL library allowing programming in Visual Basic or C++. An ioAdmin tool is also provided for easy set up and control of ioLogik servers. Simple Network Management Protocol (SNMP) is supported in all ioLogik devices.
“This new range from Moxa expands our capability in the field of remote data acquisition. Until now, we have only offered distributed I/O models that sample at relatively slow speeds, however, Moxa’s products can sample 4 analogue channels in 4ms. Another benefit of the modular design is that many modules can be connected to the Ethernet with just one port, reducing the need for switches,” says John Hayward, product manager for Measurement and Control at Amplicon.
