This command is used to verify user program and messages in processor
memory with the content in data cartridge tape, or vice versa. Although the
data table size and configuration are checked, the data table content is not
verified.
With the processor in any mode, verification can be done by pressing the
keys [RECORD] [SHIFT] [C] on the industrial terminal keyboard. The
number of user program and data table words are counted and displayed
while tape content and memory content are being compared. When
verification is complete, the number of discrepancies in processor memory
can be located and displayed as described in Section 8.3.5 and corrected by
reference to a hard copy print out. The verification process can be aborted
at any time by pressing [CANCEL COMMAND].
Accessible in any mode, the ladder diagram dump command is used to
print out a hard copy of the user program using a peripheral printer that is
connected to channel C.
This command is accessed by pressing the keys [SEARCH] 44 on the
PLC-2 family overlay. The printout will begin from the current rung,
allowing all or part of the program to be printed.
When the printout is complete, this command is automatically terminated.
This command can be terminated before completion by pressing [ESC] on
the peripheral device or [CANCEL COMMAND] on the PLC-2 family
overlay.
The total memory dump command is accessible in the program mode only.
It is used to print out a hard copy of the data table, user program and
messages using a peripheral printer connected to channel C.
This command is accessed by pressing:
[RECORD]
Set the baud rate (Table 8.B)
[SEARCH 45]
The complete memory will print out regardless of cursor position.
The data table will be printed in hexadecimal. The bit pattern for each data
table word will be as shown in Figure 8.2. In each row, the 4-digit octal
word address is the address where the left-most hex value is stored. For
example, the hex values ECCB and 024C are stored in word addresses
0020 and 0025, respectively. For more information on the hexadecimal
numbering system, refer to Appendix B, Number Systems.
