Dear Sir

SRAM backup of the machine, stored in 1MB Fujitsu Flash card, got corrupted and hence we are unable to restore Ladder although Parameters etc, we are inputting manually as per hard copy backup

We have got Fanuc Power Mate Ladder Editing cassette

We made keep relay K17.1 then PMC - Edit

Now typed few rungs of ladder with the help of hard copy on LCD and then put a function block SUB2 END2 to indicate end of the program
now to save this to CNC,
PMC - I/O, Channel =1, Device Others, Read, Exec
we get "Program data Error"

We want to make sure ladder typed using Ladder Editing cassette gets finally saved to CPU


Kindly advice

Best Regards,

Dear sir,
You can not be sure by this method , You have other option also , send the details with photograph for immediate service as usual.

The PMC configuration menu is used to display screens related to
PMC configuration data that change the target PMC, and display and
edit PMC data.
You can move to the PMC configuration menu by pressing the
[SYSTEM] key, then the [PMCCNF] soft key.
On the TITLE DATA screen, you can check the title data items and
some ladder information items. To switch to the TITLE DATA screen,
press the [TITLE] soft key.
Besides, the following operation is available in the TITLE DATA
screen.
• Moving to the TITLE DATA EDITOR screen [EDIT]
• Moving to the TITLE DATA (MESSAGE) screen [MESAGE]

(1) Title data
The following title data that is set in the sequence program is
displayed.

The FB body program can be displayed and
monitored on both the PMC screens and FANUC
LADDER-III, but can be edited only on FANUC
LADDER-III in the offline mode.

Use the operation soft keys to operate the individual screens.
To switch to the operation soft keys, do the following:
• Click the [(OPRT)] soft key, which is one of the PMC submenu
soft key.
• Enter a numerical value or character string.
To switch from the operation soft keys to a specific PMC submenu or
to the PMC main menu, click the [<] soft key.
No operation soft keys are displayed when the screen requires no
operation. In that case, the [(OPRT)] soft key is not displayed, either.
On the other hand, a screen that involves multiple different functions
consists of two or more layers of operation soft keys.
In that case, to return from the operation soft keys of one layer to
those of the previous layer, click the [EXIT] soft key

Example) Ladder display/editing screen
Operate the ladder display/editing screen by switching three layers of
operation soft keys - ladder display operation soft keys (1st layer),
ladder editing operation soft keys (2nd layer), and ladder net editing
operation soft keys (3rd layer).

Several PMC screens can be protected from unauthorized attempts to
display data or operate the screen, based on preset conditions. This
section describes such display and operation conditions.
There are two kinds of data protection for PMC. One is the
Programmer Protection Function and another is Protection of Data at 8
Levels.
The Programmer Protection Function is effective in standard. When
the Protection of Data at 8 Levels is added, the Programmer Protection
Function becomes ineffective and the Protection of Data at 8 Levels
becomes effective

PMC system provides various embedded programmer functions such
as edit, diagnosis and debugging which help the programming and
debugging of sequence program. To use these functions which may
even disable safety mechanism realized by sequence program, it is
required that the operator of these functions should be an expert who
fully understands the sequence program and the operation of PMC. It
is also strongly recommended to the developer of machine that these
functions should be protected from careless use by ordinary operators
after the machine is shipped into the field. Furthermore, if these
functions partly need to be used in the field for any purpose such as
the maintenance or adjustment, the developer of the machine should
implement any means to enable these functions after forcing the
machine in safe mode or should let the operator know and strictly
follow proper procedure to ensure the safety.
The setting parameters described in this section are provided for the
developer of machine to be able to properly program the sequence or
control the parameters for necessary conditions on which the operator
is allowed to use PMC programmer functions safely by eliminating
careless operation which may cause "stopping the ladder", "changing
sequence program" or "changing important setting data".
These parameters can be set on the setting screen or in some system
keep relays (K900 to 999).
