System Status
The Do-more CPU internally stores a record of all Information-Level, Warning-Level, and Error-Level messages generated while it is running. The System Status tab displays these messages. Any time Info or Warning or Error appear on the Status Bar a corresponding message has been generated that can be viewed on the System Status tab.
Info Messages displays the last system generated Information-level messages
Warning Messages displays the last system generated Warning-level messages
Open I/O System Window will open the I/O System View which displays a list of the current Errors and Warnings from all of the I/O Masters and the I/O Modules they control.
Error Messages displays the last system generated Error-level messages
Last Error(s) displays the
last 5 system generated Error codes. Click the Goto
button to open the code-block and position the edit cursor on the rung
that contains the programming element that is generating the Message.
Fatal Error Message (DST51) will display the error code if the CPU has a fatal error.
MSG: displays the current contents of the system-generated MSG string. Click the Goto button to open the code-block and position the edit cursor on the rung that contains the programming element that is generating the Message.
ERR: any time an Info, Warning, or Error message is generated, the ERR string will contain additional information about that message. Click the Goto button to open the code-block and position the edit cursor on the rung that contains the programming element that is generating the Error.
Note: the text of the last 8 System Errors and last 8 System Messages are also contained in the system-defined Strings called LastERR0 - LastERR7 and LastMSG0 - LastMSG7 respectively.
Click Clear All to clear all of the lists on the dialog.
