Title: DoMore and ECOM100
Post by: MAEdwards on July 17, 2015, 02:07:03 PM

I was having a discussion with some co-workers and some ADC guys when a question came up that none of us had a SOLID answer for.

Is there a need for an ECOM100 with the DoMore DM1E?

If you are using the on-board Ethernet port, is it wise to dedicate all multi-device Modbus TCP communication, programming, C-More communication, etc. to the that port OR should you allocate some responsibilities to a separate ECOM100 unit?

There are great reasons to use ECOM100s with DM1Es, generally related to load and/or network segregation. We have a number of users using both.

Bob,

With that in mind, has there been any thoughts to an ECOM100 unit using the Terminator platform?

We considered it, but I'm not sure there is enough volume for it to justify the development cost. The T1H-DM1/E is a great solution for certain apps, but it is still fairly niche.

Roger that.  Thanks, Bob.

MAEdwards, it is a good practice to separate your external I/O from HMI or programming. So being able to use an ECOM100 is nice. I would hate to loose my I/O because of a network problem in the programming plc or HMI, etc. Could be dangerous. But then again, I never had a network failure. I also communicate back and forth on the I/O and if I do not get an answer back, I know my I/O is down and can shut down safely.

Thanks PLCGuy!
I like the level of people that hang out in this room!
