USB storage
Program Download/Upload without a PC connection
If end users don’t have HX-CODESYS or are not familiar with PLC programming, the user-program can be easily updated simply by plugging a USB memory device into the PLC.
Data logging to USB storage
Logging data can be stored on to a USB memory device using a specific library.
Logging data can then be analyzed or edited remotely.
Note : Using USB memory does not mean to expand MICRO-EHV+ CPU memory.
Web visualization
Worldwide access to MICRO-EHV+ via an Internet browser.
I/O data can be monitored like HMI via a PC, Smartphone or Tablet.
Functionality
Purpose
Simple automation system
Application Example – Position control
Using the built in High-speed counter and pulse train output a simple position control system can be achieved without the need for a dedicated motion controller.
● High-speed counter | Single counter / Max. 5ch, 100kHz, 32bits 2 phase counter / Max. 2ch, 60kHz, 32bits |
● Pulse train output | Max. 3ch, 65kHz |
Application Example – Speed control using PWM output
Speed control can be achieved without a dedicated speed control unit.
Conveyor speed can be changed depending on the contents of packages.
● PWM output | Max. 3ch, 65kHz |
Application Example – Interrupt input
Specific processing can be executed without jitter.
● Interrupt input | Max. 5ch |
Easy communication with Hitachi Inverter
MICRO-EHV+ can be used as a controller for multiple Hitachi inverters.
The new option board OBV-NES can turn the MICRO-EHV+ into the ideal controller for the Hitachi NE-S1 series inverter. Communication is achieved using a standard Cat. 5 LAN cable.
By using RJ-45 splitter, multi-drop connection will be achieved easily.
Compliance with Fieldbus Standards
MICRO-EHV+ supports Modbus-TCP (master / slave), Modbus-RTU (master / slave) and EtherCAT® master.
EtherCAT is registerd trade mark and patented technology, licenced by Beckhoff Automation GmbH, Germany.
