MODULAR X6 CCTALK VALIDATOR 48

REQUEST DATA STORAGE AVAILABILITY [216]
Command not available in “Secure Mode”.
The Validator has one zone into its Flash memory used only for data storage from the Machine.
Using this command the Machine can be informed about the type of memory and the
capability of this zone:
Send:
[Dir] [0] [1] [216] [Chk]
Reply:
[1] [5] [Dir] [0] [Data 1] [Data 2] [Data 3] [Data 4] [Data 5][Chk] -> ACK
with 5 data
Where
Dir = address of the corresponding Validator
Data 1 = 2: Type of memory: non-volatile (permanent), with limited use in
number of writes.
Data 2 = 2: Number of blocks of read data available.
Dato 3 = 32: Number of bytes per block of read data..
Dato 4 = 2: Number of blocks of write data available.
Dato 5 = 32: Number of bytes per block of write data.
The user zone is 64 bytes long. It is contiguous and it is divided in 2 blocks of 32 bytes each.
Both blocks are read/write enabled and they are identified as 0 and 1.
The user zone is part of the Flash memory of the microcontroller of the Exits Module of the
Validator. This memory lasts 10.000 writes (typical). The stored data are not modified if the
Validator is powered-off and they are available after the power-on. The contents of this zone
are not modified if the Sensor Module is changed or modified, neither when the Validator is
teleprogrammed nor when the firmware is updated.
The contents of this zone can be modified (erased to 0) if the Exits Module is damaged and it
implies to replace the microcontroller or reprogram the firmware in factory.
In the paragraphs 5.30- READ DATA BLOCK [215], and 5.31- WRITE DATA BLOCK [214], the
details of use of the read and write in this zone are written.
