Diagnostics Menu
The DIAGNOSTICS menu option permits the user to view basic information about the system. The information
can then be used to readily troubleshoot problems when they occur. Most of the screens available under this
menu option are view-only screens and information displayed cannot be changed by the user. There are a few
screens available which have selected parameters for which data entry is possible. The menu selections include
System Info, View Discrete I/O, View Analogs, View Network Communications and Override Discrete I/O.
System Information
Selecting SYSTEM INFO will display the System Information screen. Information displayed includes the
dates for last memory initialization and system reset, status on system options such as modem
communications and frame statistics.
View Discrete I/O
The VIEW DISCRETE I/O screens display discrete Input and Output information from the unit. Channel
assignment, signal name, input/output designation and current state of the signal are displayed for discrete
I/O racks.
View Analogs
The VIEW ANALOGS screens display analog signal information from the unit. Channel assignment, signal
name, current value, units of measurement and hexadecimal equivalent values are displayed.
View Network Comm
The VIEW NETWORK COMM selection displays the current communication status for various units
involved in system communication such as the modem, PC or other network connections. Current status, last
error, total error count and message count are examples of the parameters which may be displayed here.
Override Discrete I/O
The OVERRIDE DISCRETE I/O screen allows the user to set the state of certain discrete outputs. It also
allows the user to simulate certain discrete inputs to an active or inactive state. This feature is for diagnostics
purposes only and will only function if the system is off-line.
NOTE: The user is responsible for knowing the consequences of manual control actions. Please use with
caution.
