Hi Tim
Thank you
That might work.
I have 2 scenarios – the immediate one;
We have a unit installed in the parking lot of a client.
Client does not have a BMS so warning and alarm notification is by client call out to technician.
Client wants to be able to see our HMI [ via SBC MicroBrowser – only browser that works with the HMI] from his office.
So my option is:
Install a cellular modem/router at site [ site is 4hrs remote from nearest technician ]
- Goal is to get the eWON to send at least a warning email [ I think I can program it to send an email on a TAG change of state, we have flags for “alarm” condition. Or I could
install an I/O board and have the PLC close a dry contact to create a trigger event.*
Technician would then use TeamViewer to access our local laptop and connect to the HMI
I also want to poll our PLC via the eWON and log key data for review and trend machine performance.
- I think I can program the eWON to log the data and push it out via Talk2M, but that’s unclear on the website. So I was going to install a datalogger on the laptop and just have
the tech copy and send it to me during regular service visit.*
It’s unclear of the eWON and HMI are on the same network, would the Talk2M VPN allow access to the HMI? Or does the eWON have to be the router, and I need to add a port?
I also have a SPM Intellinova SPM vibration device on the system, it uses the cell modem to push vibration data to our server in Belgium for historical trending and analysis.
Thoughts?
Thanks again for your help!
