Re: [External] Re: Bacnet/IP to Modbus TCP Gateway Hardware Recommendations

Heinz,

Thank you for the recommendation. We are considering using the MOXA 5217 gateway to set the BACnet values to "read only" before passing them onto EPICS as MODBUS records. This will be our method to prevent accidental write operations from EPICS, which are undesirable in our application.
