SetEchoMode
SetEchoMode verifies whether data transfer is intact.
See also Chapter 8.1.9 ”Fault Diagnosis and Functional Test”, page 223.
SetEchoMode passes an 8-bit value to the scan system with Code
LOW
. As a consequence, the
scan system transmits a 16-bit value (16-bit protocol) or 20-bit value (20-bit protocol) on the
corresponding status channel to the RTC board. If the data transmission has been error-free,
with this:
• The upper 8 bits and Code
LOW
are identical
• With the 16-bit value, the lower 8 bits / with the 20-bit value, the next lower
8 bits and the complementary value of Code
LOW
(NOT Code
LOW
) are identical
Example with 16-bit protocol: For control_command(1, 1, 0x210A) and if data transfer is error-
free, (get_value(1) AND 0xFFFF) returns 0x0AF5.
Example with 20-bit protocol: For control_command(1, 1, 0x210A) and if data transfer is error-
free, (get_value(1) AND 0xFFFF0) returns 0x0AF50.
