The 8 or 14 output lines of the remote socket can be set at will both in man-
ual operation and during a method run with the "CONTROL" command
(CTRL_RM) by setting an 8 or 14-place bit pattern in which each bit is allo-
cated to an output line. The output lines can also be set manually.
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:
CTRL_Rm Remote A Signal *******1
sets output line 0 to active (=set) which, for example, if a
Metrohm Ion meter is connected would have the effect of a
start command.
It is recommended that non-relevant output lines are masked with an aster-
isk (*) so that the status of the line is not changed.
The 8 input lines of the remote socket can be scanned during a method with
the "Scan" command (SCAN_RM). Execution of the method is stopped
until the pre-determined bit pattern coincides with the effective condition of
the input lines (e.g. the status of the ready line, for querying the end of a
determination from a Metrohm instrument). This is done by setting an 8-
place bit pattern in which each bit is allocated to an input line. When they
coincide the method will be continued with the next command. In manual
operation the status display of all input lines can be scanned.
Input 7 6 5 4 3 2 1 0
Bit 7 6 5 4 3 2 1 0
(Bits are always numbered from right to left)
Example:
SCAN_RM Remote A Signal *******1
waits for an active input line 0 (1=set). This line will be set by
e.g. a Metrohm instrument when a determination has been
finished and a start signal can again be accepted.
Input lines which are not of interest or for which no defined status can be
predicted should also be masked with an asterisk (*) here.
0 = inactive (high)
1 = active (low)
* = no change
0 = inactive (high)
1 = active (low)
* = arbitrary
