† DO I/O timing is the time to output values to discrete output module.
†† Service Request #14 (Clear Fault Table) timing was done when fault table contained no faults.
††† Service Request #26/30 (Interrogate I/O) timing was done when I/O configuration was empty and both an MDL740 (16pt out)
and MDL640 (16pt in) were physically present.
