time not right

Hi All
I have an NI-2100 that will not maintain its time, I have even added it to my RMS and this unit lose's hours everyday. I could understand if the battery was dead but the power is always on and the unit still lags time 10-20 minutes / hr. Sounds like a bad internal clock to me. Has anyone else had this type of issue?

Not on a Netlinx master but once on an older Macintosh with the old on-the-board clock/battery chip. In that case it ran really fast. I attributed it to a bad Heisenberg compensators not protecting it from the effects of uncertainty.

Or sometimes the flux capacitors just go bad

Only when your warp core is operating at less than 98% efficiency.

Actually, this can be directly linked to the world-wide shortage of pure dilithium crystals.

Can you call tech support and get this RMA'd? Let them know to send it to Rick in engineering. I'd like to understand what the issue is with this unit and make sure it isn't something more systemic.

Most likely your battery has gone bad. On a master, there are actually 2 clocks. The real-time clock and the run-time clock. The real-time clock is tied to the battery and is read at startup to initialize the run-time clock. Then, periodically during execution, the run-time clock is checkpointed back with the real-time clock to correct any drift. But if the real-time clock is not working (due to a dead or failing battery) the run-time clock will continue to drift.

The solution is to either a) replace the yellow snap-hat battery or b) switch the master to use Network time if the master has connectivity to the internet. Under Network time, the master will periodically connect to a Network time server on the internet and set it's time appropriately.
