10.5.2 TT4000S Display Screens
The TT4000S displays a comparable set of screens to the full TT4000 except that the
data is in numerical form and graphics are limited (Figure 19).
10.5.3 TT4000 Data Collection and Display
The Discrete Event Log records changes in status for all defined discrete inputs,
including operator commands, alarms and shutdown annunciations, and key sequencing
and status signals. Up to 5000 events are stored and can be viewed and sorted by
heading.
Analog Data are collected and saved to disk. The standard data files are:
Hourly Log - data are read at hourly intervals for 2 years. Each year’s data are stored in
a separate file. Data are recorded whether or not the equipment is operating.
Minute Log - data are read and stored at one-minute intervals for the previous 62 days,
one file for each day.
10 Second Log - data are read at 10-second intervals for the previous 31 days, one file
for each day.
Trigger Log - data are read at one-second intervals for 6 minutes before a “trigger” event
that is defined in the software. The standard trigger is a shutdown. Six minutes before the
trigger of data are written to a file. Up to 50 trigger logs files can be stored.
10.5.4 TT4000 Display Language
In addition to English, dual language screens are available with English and Spanish
(Latin America), Portuguese (Brazil), French, German or Chinese (simplified). Other
languages can be provided as custom features.
10.5.5 TT4000 Operating Modes
There are two operating modes for the TT4000 software: Design Time and Run Time.
Design Time is used to create or modify a project’s working files. Run Time uses those
files in the normal equipment operation.
10.5.6 Supervisory Control Interfaces
The Turbotronic 4 control system can transmit data to, and receive control instructions
from, a supervisory control system. All analog data and the status of all discrete values
