Lighthouse PLCs, Inc. : Automation Forum
THE PURPOSE OF THIS FORUM IS: AUTOMATION SOLUTIONS. IF YOU ARE A PERSON INVOLVED IN SOME ASPECT OF AUTOMATION, HAVE AN APPLICATION YOU JUST CAN'T QUITE GET A HANDLE ON 
- HAVE A PRODUCT QUESTION - OR MAYBE HAVE AN ISSUE WITH SOMETHING (EVEN IF IT IS WITH US 
), IT IS POSSIBLE YOU WILL FIND THE ANSWER HERE!!
OR, IF YOU ABSOLUTELY KNOW THE ANSWER, OR EVEN THINK YOU KNOW THE ANSWER, THEN JUST POST IT! MAKE THAT REPLY!
YOU ARE PROBABLY RIGHT ON THE MARK, AND MIGHT BE ABLE TO HELP SOMEBODY OUT!! 
AND, IT COULD BE YOU THAT NEEDS HELP NEXT TIME. AFTER ALL...(REALLY?).. ARE WE NOT ALL "CHILDREN" - AT VARIOUS POINTS ON THE LEARNING CURVE OF TECHNOLOGY" ??? (I know I've still got a lot to learn and I've been at it for... well since 1970!)
Hopefully the information presented here will help provide solutions to some of today's automation challenges. Some issues are probably old, some are probably new. Many are products of the economy, the resultant reduction in manpower, exacerbated by aging equipment crippled by decreases in maintenance budgets. The ULTIMATE goal here is that we all become more successful in our careers and chosen professions.
MAYBE THIS FORUM CAN HELP!!!

IMPORTANT ANNOUNCEMENT
Date: March 1, 2007
Hitachi has announced a "Stop in Production" for the EC-Series, The EM/EMII-Series, and the H200/250/252-Series.
REASON: The components used to create these models have been discontinued.
SCHEDULE: The production will stop in March of 2008. After that time, orders will be filled as long as stock is available. It may be possible to get units repaired after that time, dependent upon availability of parts.
REPLACEMENT The Hitachi recommended replacement for the EC is the Micro-EH series. The recommended replacement for the EM, EMII and H200/250/252 is the EH-150.
NOTE: The program running in your EC/EM/EMII will work just fine in the Micro-EH and/or EH-150. There are at least two "translation" programs available, which will adapt your program for use in the newer models. This is necessary, because the "H" type processors in the Micro-EH and EH-150 use the same HI-Protocol as the Hitachi Large-H family. This protocol is fundamentally different than the protocol used in the "E" series processors. You will find that this upgrade will run your current program just fine. In most cases, it will even run faster (faster scan times) and offer you more versatility that what you had previously (greater functionality).
If you currently use the H200/250/252 system, your project will run properly in the EH-150, as long as the I/O addresses match. (The H200 CPUs already use the "H" series processor).
I would be happy to address your concerns, or discuss various upgrade opportunities.
