Auto-zero on the ATEQ device
Master
Slave
— Select the program on which you want to make the
auto zero
— Write at the address 08(h) the identifier number of
the special cycle for an auto zero
— Activate the “Start” and the “Start special cycle”
commands:
Write at the address 00(h), the value 0006(h)
Byte 0 = 06(h) (Bit 1 = 1 and Bit 2 = 1)
Byte 1 = 00(h)
Acknowledgement
Command echo:
— Byte 0 = 06(h) (Bit 1 = 1 and Bit 2 = 1)
— Byte 1 = 00(h)
Command error code:
— Byte 2 = FF(h)
— Byte 3 = FF(h)
(if command error code = FFFF(h), command is in
progress)
Running “Start” and “Start special cycle” commands
Command finished
Command echo:
— Byte 0 = 06(h) (Bit 1 = 1 and Bit 2 = 1)
— Byte 1 = 00(h)
Command error code if the command is correctly
carried out:
— Byte 2 = 00(h)
— Byte 3 = 00(h)
OR if an error occurred during the command:
— Byte 2 = 06(h) (Bit 1 = 1 and Bit 2 = 1)
— Byte 3 = 00(h)
— Wait the end of the command:
command echo = 0006(h)
command error code ≠ FFFF(h) (end of command)
— Deactivate the “Start” and “Start special cycle”
commands:
Write at the address 00(h) the value 0000(h)
Byte 0 = 00(h) (Bit 1 = 0 and Bit 2 = 0)
Byte 1 = 00(h)
The master instrument must always set to zero the command bit. If it is not done, the slave instrument
will not detect the following command on this bit. It has detection on the rising edge (when the bit
state goes from 0 to 1).
