Hitachi launches PLC with five times faster speed
May 2007
PLCs, DCSs & Controllers
Hitachi has recently introduced the EHV Series PLC CPU. This is according to Mike Cronin, managing director and owner of Elquip Solutions, Hitachi's South African representative and sole agent.
"We are very pleased to be able to bring Hitachi's impressive, recently launched EHV Series to the South African market. By partnering with companies of Hitachi's status and reputation, and being included in their network of agencies, we are able to ensure that local industry has access to the latest and most innovative technology," comments Cronin.
He explains: "The EHV CPU can process each binary command in 20 nanoseconds, which translates to a program of 80 kB completing in 1 ms. Memory areas for Program, Data and Comments are separated, so that in total, more memory is available for the user. The EHV-CPU can be used in conjunction with all available input/output modules of the EH150 series PLC, but the CPU at the heart of the system can operate at five times faster speed."
"The new Control Editor software allows for fast data transfer, including on-line change while running. Control Editor was developed with user-friendliness in mind. A windows-type tree structure simplifies project management, and multiple windows showing different program sections simplify the editing and debugging process; while ladder programming allows for a fast implementation of the application logic structure," continues Cronin.
"For open networking and communication the EHV-CPU has USB, serial and for the first time an Ethernet interface on-board as standard. These interfaces allow for fast and easy communication with other Hitachi CPUs and fieldbus systems. A total of eight additional communication modules can be connected as well. An LED display provides fast information for the operator with error codes and operating status."
Cronin concludes: "Hitachi has established a name for itself locally, as having the capacity to bring big-brand quality and technology to the end-user - with the advantage of being extremely competitive in pricing."
