Data: The states of the relay and digital inputs at the time of capture for both Option
cards 1 and 2. If the option card does not support I/O Change Records (no card or not
a Digital Option Card), the value will be 0.
NOTES:
• An I/O Change log record will be taken for each Relay and Digital Input that has
been configured in the Programmable Settings to record when its state changes.
• When any one configured Relay or Digital Input changes, the values of all Relays
and Digital Inputs are recorded, even if they are not so configured.
