This read-write Integer32 sets how often, in milliseconds, the IO module rereads its digital input values, ranging from 1000ms (1s) to 10000ms (10s) in 100ms increments. A shorter interval gives an admin faster detection of input state changes at the cost of more frequent polling overhead. For example, setting this to 1000 makes the module check inputs every second, which also determines how quickly hm2IOModConfigDigInputLogEvent and SNMP traps fire after a change.
