Known Limitations

At the time of this document update, there are several known limitations for a Supervisor running on a 64-bit Windows operating system. Although most of these do not apply to a typical Supervisor, they should be understood before installation time.

These 64-bit Windows platform limitations include the following:

  • NRE serial support is available for a 64-bit Windows platform. However, serial-based drivers (for example, modbusAsync, flexSerial, various legacy drivers) are not typically licensed on a Supervisor, and therefore are not fully tested or supported on a 64-bit platform.

    Exceptions to such license rules can occur with 64-bit engineering workstations and demo machines. Again, 64-bit serial operation is not fully guaranteed.

    A known issue with the 64-bit serial library may present itself in initialization phases,with usage of a 64-bit Niagara Serial Tunnel client. For related details see the Niagara Drivers Guide.

  • Lonworks FTT-10 is not fully supported on a 64-bit Windows platform—although there are Echelon 64-bit drivers, most are 32-bit drivers in a “64-bit wrapper”, and are likely unsuitable. Further, a Supervisor is not typically licensed for Lonworks. However “LonIP” is supported.
