Operation Description Timing
(2)
Throughput The delay time between the module receiving a pulse and the
updating of its physical outputs. Sequencer: 1.8 ms
Range: 3.9 ms
Rate: 70.0 ms +
Rate Period
Minimum wait time between
range boundaries Minimum amount of time (between range or step boundaries)
required to ensure a range or sequencer step is not missed. Sequencer: 2.5 ms
Range: 3.0 ms
Rate: 70.0 ms +
Rate Period
Input file update time The time required for the module to make a change of input status
(I:e.0 to I:e.7) available to the user program. Sequencer: 45 ms
Range: 60 ms
Rate: 35 ms
Physical output response time
(under SLC control) The time required for the module's Direct Outputs Field to respond
to control commands from the user program. Sequencer: 45 ms
Range: 60 ms
Rate: 35 ms
Z input reset response time.
Reset to zero (0) The time required for the module to respond to an external Z input
event and reset the pulse counter to 0.
4.0 µs
