Just putting this out there that SEL has a great “Embedded Automation Computing Platform” under the model SEL-3354 preloaded with “Substation Server” which can convert IEC-61850 to a handful of protocols that Ignition does support. If you add a IRIG-B signal it can even fill in timestamp data and serve as a NTP server. If you were feeling really ambitious, would be possible to get an Ignition gateway residing on it also.
