Chapter 4 - BRI Commands BLOCKPERMALOCK READ Purpose: Syntax: Examples: This command allows you to read the lock status. BLOCKPERMALOCK [flex_query_selector] READ [data_field]*[TAGTYPE=] [WHERE ] [PASSWORD=] data_field = Specifies a bank, offset, and length in this form: HEX(:,). = The bank should always be three. = The offset is the "BlockRange" parameter of the specification. It specifies the range of blocks for the which the status should be returned. The range starts at and ends (16*)-1 blocks later. The result of a "BLOCKPERMALOCK READ" command is a hexadecimal value that represents a bit map of locked and unlocked blocks. A one bit indicates that the corresponding block is locked. A zero bit indicates that the block is unlocked. The most significant bit of the resulting hexadecimal value corresponds to the lowest address block. Example 1: BLOCKPERMALOCK READ HEX(3:0,1) HH0123456789ABCDEF01234567 H0800 Read the permalock status of the first 16 blocks of user memory. Example 2: BLOCKPERMALOCK READ HEX(3:3,1) HH0123456789ABCDEF01234567 H0001 Read the permalock status of the third 16 blocks of user memory. Example 3: BLOCKPERMALOCK READ HEX(3:2,2) HH0123456789ABCDEF01234567 H00000001 Read the permalock status of the second and third 16 blocks of user memory. Example 4: BLOCKPERMALOCK READ HEX(3:2,1) HEX(3:3,1) HH0123456789ABCDEF01234567 H0000 H0001 Read the permalock status of the second and third 16 blocks of user memory.

Basic Reader Interface Programmer Reference Manual
BLOCKPERMALOCK READ
Purpose:
This command allows you to read the lock status.
Syntax:
BLOCKPERMALOCK [flex_query_selector] READ
[data_field]*[TAGTYPE=<tagtype list>] [WHERE <data condition>]
[PASSWORD=<“access_password”>]
data_field = Specifies a bank, offset, and length in this form:
HEX(<bank>:<offset>,<length>).
<bank> = The bank should always be three.
<offset> = The offset is the “BlockRange” parameter of the specification. It specifies
the range of blocks for the which the status should be returned. The range starts at
<offset> and ends (16*<length>)-1 blocks later.
The result of a "BLOCKPERMALOCK READ" command is a hexadecimal value
that represents a bit map of locked and unlocked blocks. A one bit indicates that the
corresponding block is locked. A zero bit indicates that the block is unlocked. The
most significant bit of the resulting hexadecimal value corresponds to the lowest
address block.
Examples:
Example 1:
BLOCKPERMALOCK READ HEX(3:0,1)
HH0123456789ABCDEF01234567 H0800
Read the permalock status of the first 16 blocks of user memory.
Example 2:
BLOCKPERMALOCK READ HEX(3:3,1)
HH0123456789ABCDEF01234567 H0001
Read the permalock status of the third 16 blocks of user memory.
Example 3:
BLOCKPERMALOCK READ HEX(3:2,2)
HH0123456789ABCDEF01234567 H00000001
Read the permalock status of the second and third 16 blocks of user memory.
Example 4:
BLOCKPERMALOCK READ HEX(3:2,1) HEX(3:3,1)
HH0123456789ABCDEF01234567 H0000 H0001
Read the permalock status of the second and third 16 blocks of user memory.
