ES601 Plus OPERATING MANUAL
7.4.2 Safety Test Execution
Under computer control, a Safety AutoSequence is initiated by means of this exchange:
a. PC software transmits
RSAF\r
to ES601
Plus
via the serial connection.
b. ES601Plus responds by returning
*\r
(0x2A 0x0D) to the PC. If the RSAF\r command is received by ES601
Plus
without
errors, the *\r response should be returned to the PC within 0.2 seconds.
c. PC software sends one ASCII character to ES601
Plus
to specify the AutoSequence.
Send:
a (0x61) to select AutoSequence #1; or
b (0x62) to select AutoSequence #2; or
c
(0x63) to select AutoSequence #3;
...
and so on up to x (0x78) to select AutoSequence #24. PC software must send this
character within two seconds of the *\r response from ES601
Plus
, otherwise
ES601
Plus
will time out and abort the protocol. If ES601
Plus
receives a character
other than
a
to
x
, ES601
Plus
returns
?\r
to the PC and aborts the protocol.
As an alternative to sending a lower-case letter, PC software can alternatively send an
upper case letter:
A (0x41) specifies AutoSequence #1, B (0x42) specifies
AutoSequence #2, and so on up to X (0x58) which specifies AutoSequence #24. The
difference is that sending lower-case causes ES601
Plus
to execute a complete
AutoSequence as if the test had been selected from the SAFETY
AUTOSEQUENCE menu, beginning with CONNECTION instructions,
APPLIED PARTS setup, and SEQUENCE control menus. Alternatively, for
upper-case letters, these initial information and setup menus are bypassed and
execution of the test begins immediately with the first measurement.
