4.8 Remote Interface
730 Sample Changer, Detailed Description
120
Various remote cables are available to use the specific functions
of the individual instruments of the various Metrohm model lines
(see page 15ff). Metrohm also delivers special cables on request
suited to the customer’s needs, which allow complex couplings
(including foreign instruments).
The 14 output lines of the remote socket can be separately set
(statically) in manual operation as well as during method process-
ing with the "Control" command (CTL). A 14-place bit pattern
must be defined for this. Every bit is assigned to an output line.
Output 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Bit 13 12 11 10 9 8 7 6 5 4 3 2 1 0
(Bits are always numbered from right to left)
Example: "CTL Rm ∗∗∗∗∗∗∗∗∗∗∗∗ 1 ∗ "
sets the output line 1 to active (=set), that for exam-
ple, would cause a STOP command with a connected
Titrino.
It is recommended to mask the output lines that are not relevant
with a asterisk (
∗ ) to prevent alterations to these line states.
The 8 input lines of the remote socket are queried during method
processing with the SCAN command (SCN). Method processing
is interrupted until the predefined bit pattern compares to the ef-
fective state of the input lines (for example, the status of the ready
line, for catching the end of a titration with a Titrino). An 8-place bit
pattern must be set for this. Every bit is assigned to an input line. If
there is correspondence, method processing will continue with the
next command line. During manual operation the SCAN command
serves as a status display of all input lines.
0 = inactive
1 = active
∗ = no change
