    Run with either an FX3u-48MR (or MT).  They are a good physical replacement for the FX2n range and the programming software is the same.  So when you do find your original software you will be able to easily program it into the FX3u.

    I just use a fine tooth metal cutting blade. Tried the diamond tip but they seem to just be a waste of money

    Yep, I agree.  Four holes in each corner widened using a step drill to the size that I want (about 12mm).  2" duct tape (not masking tape)  along all four sides to the outer edge of the step holes giving me the cut line.  Then just cut along four straight lines and the centre piece drops away.

    The trick for me though comes before this.  I always have a panel template engraving manufactured.  They are not expensive typically only £40.00 UK price.  I use Pantograph Services (http://www.pantograph.co.uk/).  They work from a dimensioned PDF (see attached example).  As an extra this gives you text engraving around your buttons and indicators.  it is well worth doing.

    With the panel engraving as a template you mark out the position of the cutout easily getting perfect HMI line up with your buttons and indicators.   Drill your four holes, widen them, add the duct tape, get cutting.  A Bosche hacksaw blade in a mains powered jig saw works for me.

    I pull the 22.5mm holes through with a circular hole puller, driven with a 1/2" impact driver.  Works well up to and including 1.0 x 0.8m door panel sizes.

    Not sure if it would handle stainless though.  Never tried.

    Besides the FX2N doesn't support ethernet. If you have an Got HMI connected to both it could also do this job.

    Really?  I know you can get LAN modules for the FX2n so they must only be for slave operation via the MC protocol.  My plan was to always have an FX3u in the system so that it could act as master and map the FX2n.  A pretty simple requirement I would have thought, although I admit I have yet to get to the bottom of it.

    I am looking to map an FX2n's I/O into a second FX3u PLC on a local PLC to PLC link.  I was wondering which interface unit I could use to make this happen.  Would it be a LAN link, RS485 or Fieldbus of some sort?   I have no preference at this stage.

    Thanks in advance.

    If you don't use screening you can always twist the two cables tightly together.  It helps minimise pickup.  Obviously not as good as full screening though.

    You could switch to a different block that shows everything else identical apart from the temperature fields.  These would have different offsets and gains to do the Fahrenheit conversion.

    Use Gain 1.8, Offset 32.

    Does anyone have the .bin file that I would be able to use to reload my vs 6.02 firmware for the E200.  Running E designer 7.5 and it doesn't recognise the E unit I have.  

    Thanks in advance

    All of the info I have seen so far on line shows a PLC or a network of PLC's on COM2.  It being a HMI it would have to connect to something intelligent downstream so my question to you is, is the HMI configurable for non PLC connection?  It may only be linkable to PLC's and as you have not connected a PLC on com2, it is shouting at you. 

    Second question. Has the HMI got a driver for the weighing device, or does the weighing device have an OMRON PLC emulation mode?

    That's all I have I am afraid.  I came across this ...

    ... in my on line travels.  It may have a pointer for you.  Sorry I don't have a definitive answer for you.
