I have a system that’s connecting to two PLCs using the Modbus driver and another system using an Allen Bradley driver.
We are intermittently seeing tags go to bad quality. Rebooting the Ignition server fixes it.
It isn’t happening every day but it’s becoming a problem for our demos.
We’re running these drivers
AB driver 5.0.0-rc1 (b2019040123)
Modbus driver 6.0.0-rc1 (b2019040123)
