This sets, in non-volatile memory, the elapsed time between two readings of a TMS's error counter (too long a period risks the counter overflowing; a value of 0 means read on every token ring driver poll). Valid range is 0 to 5000 (milliseconds); factory default is 5000. Setting this object stores the new value for the next reset, but does not change the currently-effective fibTmuFunctReadPerRun value until the system is actually reset. Admins shorten this if error counters are at risk of overflowing between reads on a very busy or noisy ring, then schedule a reset to apply the change.
