Data Logging
Data logging is normally configured in a configuration file (see page 66), but you can change it in the
Inspect window. Remember that changes made here cannot be saved to a configuration file,
however. To change configuration, with the I/O unit’s IP address in the Inspect window, click Data
Log➞Data Logging Configure. For help, see the information in the steps on page 66.
To read the data in a data log you have set up, use PAC Manager’s Inspect window. See instructions
on page 68. To clear all data from a data log, see page 69.
Reading or Changing PID Loops
See the steps in “Configuring, Viewing, or Changing PID Loops” on page 147.
Reading or Changing Events and Event Messages
Digital, alarm, serial, timer, and Wiegand events are normally configured in a configuration file. Event
messages are configured in a configuration file if you are using PAC Control; otherwise, they are
configured in the Inspect window. See Chapter 4, “Setting Up Events and Reactions,” for
configuration steps on all events and event messages.
However, you can read current events and also change their configuration in the Inspect window.
Digital Events are shown below as an example.
The current state of the Scratch Pad bitmask
(as of the Status date and time) is shown here.
Choose the event
number from the
drop-down list.
This event’s
configuration data is
shown here.
