leitmotif/Ken,
I'm in the process now of convincing the customer to swap the ComBox-E for an S.
I've worked with more than a dozen Modbus Atlas Copco over the past year or so, so I know how well that works.
That said, until I actually get an OK that the units are being swapped out, I'm going to continue to try to figure this out -- and figure it out without the luxury of even having the ComBox-E to work with.
Any assistance you can give will be appreciated. Ken, any sample code or info you have would be awesome -- please just email to
[email protected], or I can PM you, or whatever's easiest for you.
As for what I'm trying to accomplish, I solely want to read info back for logging/display on a local HMI, and for plant use in their SCADA system.
Specifically:
In "Modbus-speak" I'd like the "General Compressor Condition" coils 0001 through 0010, or I guess Modbus register 0403d, which looks like it's Parameter ID 0401 in Ethernet/IP.
Past that, I'd like outlet temp, pressure, entering/leaving water temps, and the like.
Again, I'm working towards getting this E swapped for an S, but until I'm for sure on that, I want to keep trying to plug away on this.
Thanks all,
Chris
