How to increase binary counters in srt512/sri512 using WRITE_BLK()?

I'm really curious about how to increase binary counters in srt512.
I bought some of srt512 cards but i can't increase any of them.

Datasheet said it is protecting by anti-tearing protection, and developer can define the value but i can't.
(but Decrement is worked right.)

someone please tell me why i can't ..

anti-tearing is a protection to ensure an operation happen or not.  Like atomic in databases. 
It protects you from start writing a block and then move the card away from the reader and making the card powerless,  leaving a "half" written block. Nothing to do with other restrictions like access.

you would need to read the datasheet and see if the block you want to write to has read/write protection,  locked, or other accessprotection.  smile
