What is the Module ID and Block ID

[Jacksonlv]

I am using the nrf51822 and I want to use the pstorage library to save some data which is "power lost can save",but I cloud not find the example of it.I am using the SDK 8.1.0 and after init the pstorage by pstorage_init() function.I got error when I store and load .I think maybe is the module ID and block ID problem.I don't know if I set it at this way is right pstorage_handle_t PID_local={1,260096};

I am using SDK 8.1.0 and I using the example in here.It worked fine.Now I want to use the pstorage function with BLE mesh but I found that after I comment the "ble_stack_init();" function ,the Serail always prints "pstorage ?".Can you tell me why?
