dear everybody
as I know, setting password plc omron TPM1A, it has two ways to setting password
I am test setting password for plc omron types : TPM1A
The first way : the following program should be written in the first rung in the plc.
LD AR10.01 FUN49 000ch #****(****= password )
Example whole program protection.


------[ AR10.01]---------------[FUN49 (000) ]
00
00
password 1235
-------[0000]---------------------------------[ 1000]
-------[0001]---------------------------------[1001 ]
----------------------------------------------- [END]

now I test the use software XTAL to unlock password TPM1A, I see that
software XTAL unlock password for CPM1A and TPM1A ok, or use software XTAL to unlock password for plc TPM1A I see unlock ok
you look at the attached image above
I unlock password successfully or unlock password ok , no problems

second way :
I test installtion password protection for plc TPM1A the following second way.

an example of partial program protection


-------[0000]---------------------------[10000]
-------[0001]---------------------------[10001]
------[ AR10.01]---------------[FUN49 (000) ]
00
00
password 1235
-------[0000]---------------------------------[ 1003]
-------[0001]---------------------------------[1004 ]
----------------------------------------------- [END]

this following second way:

I also use software XTAL to unlock password protection but software XTAL unlock password unsuccessful
in the second case or second way I unlok password completely failed
when I open software cx- programmer
-----> plc ---> upload plc program but I get the partial program back and many 'NOP'.
I don't see command [END]
----------------------------------------------------------[ NOP (00)]
----------------------------------------------------------[NOP (00) ]
----------------------------------------------------------[ NOP (00)]
----------------------------------------------------------[NOP (00) ]
----------------------------------------------------------[ NOP (00)]
----------------------------------------------------------[NOP (00) ]
----------------------------------------------------------[ NOP (00)]
----------------------------------------------------------[NOP (00) ]
