LOAD Command
The LOAD command has the form:
LOAD
The LOAD command causes the Ethernet Interface to enter the “load” state as described in
Chapter 2, Installation Procedure 4: Configuring and Downloading a Station. After the
LOAD command is entered, the module must have its software reloaded and reinitialized
before any further processing may take place. Any data transfer between the Series 90-70
PLC and the network when the LOAD command is issued is permanently lost.
A typical LOAD command is shown below:
= load
Forcing software load
LOG Command
This command prints entries from the Exception Log. Log entries remain in the log until
they are explicitly cleared by using the CLEAR LOG command or until they are overwrit-
ten by more recent data. The log is maintained as a circular list where new data over-
writes the oldest data in the list. An arrow points to the most recently logged event.
The LOG command has the form:
LOG
A typical LOG command is shown below:
> log
<<< Exception Log >>> Entry
Date Time Event Count 1 2 3 4 5 6
01-FEB-1996 00:00:00.0 1H 1H 00H 0000H 0000H 0000H 0000H 0000H
->01-FEB-1996 04:37:15.3 cH 14H 00H 0103H 0000H 0000H 0000H 0000H
The Date and Time columns contain a time stamp of the last occurrence of the logged
event. The Event column gives the kind of event which occurred. The following table
lists the possible values for events. The Count column contains a repetition count for the
event. If events which are identical occur regularly, they can easily flood the log with
useless entries. Instead of recording each such repeated event in detail, the log simply
keeps the time stamp of the latest and a count of the number of repetitions of the re-
peated event. The log Entry contains detailed information about the event.
Note
The timestamp used is the current date and time of day as known by
the TCP/IP Ethernet Interface. This is the same time that is displayed by
the DATE and TIME commands and changed by the CHDATE and
CHTIME commands.
