4.3 Methods 4.3 Methods 4.3.1 Structure of a method A method consists of the following parts: • Number of samples to be processed • Process sequences (start, sample and final sequence) • Definition of the various instrument settings (changer settings, manual stop options) These method parameters are accessible by pressing the key (see section 4.3.2). With the key, methods can be stored, loaded and deleted (see section 4.3.8).
4 Operation 4.3.2 Method parameters – key PARAM The key combines the most important parameter settings for the 766 IC Sample Processor. All these settings constitute a method and may be saved as such (see section 4.3.8).
4.3 Methods parameters >start sequence Start sequence of a sample series The processing sequence entered here is executed once at the start of a sample series. This can be useful for switching on external devices, for example. In this submenu up to 99 command lines can be entered as a processing sequence (see section 4.3.3). parameters >sample sequence Processing sequence for each sample This processing sequence is executed during the processing of every sample of a series.
4 Operation parameters >manual stop Actions at manual stop The following entries define the commands or signals that are transmitted via the interfaces when the key is pressed. This enables peripheral instruments connected to be stopped automatically. >manual stop CTL Rmt: ************** 14 bit (1,0 or *) Signal output via remote interface The 3 lines 11, 12 and 13 are occupied for the swing head and are therefore ignored (see section 5.1).
4.3 Methods 4.3.4 LEARN mode LEARN HOLD When editing a method, the parameters of a command are most easily determined experimentally, i.e. by manual execution, and it is for this reason that certain commands are "teachable". The LEARN function makes the manual execution of particular changer commands possible during the editing of a sequence. The resulting parameters (for example, the lift position or the status of the input lines) can be taken over in the current command line.
4 Operation 4.3.6 Commands for sequences The following commands are programmable within a sequence. Most of them are also available in manual operation but may vary partially in their operation or exhibit a limited parameter selection (see section 4.4). SAMPLE SAMPLE 7 >start sequence 1 SAMPLE: = 1 =,+,–; 1…999 Define current sample position The SAMPLE command defines the rack position for the current sample (SAMPLE = X). This is stored as a index variable.
4.3 Methods LIFT LIFT 9 >sample sequence 3 LIFT: 1 : rest mm Position the lift work,rinse,shift, special,rest,0…125 mm Raising or lowering the lift to a defined position. Work, rinse, shift and special position are rack-specifically defined in the Configuration menu under '>rack definitions' (see section 4.2.1). The rest position is the zero position (0 mm) of the lift, i.e. the upper stop. Each lift can also be precisely positioned to the millimeter.
4 Operation Predefined bit patterns are supported which can be selected by short names (e.g. 'Ready1' or 'End2'). signifies a static "ready" line of an external instrument. 'End' stands for pulse signals, for example EOD (= end of determination). When scanning for pulse signals parallel scanning of several lines cannot be applied. 'Ready' Setting special bit patterns allows flexible control of connected instruments.
4.3 Methods More detailed information about the syntax can be found in the Instructions for Use of the instrument from which the status messages should be transmitted. CTL CTRL 2 With the LEARN function transmitted data (= character strings) can be taken over interactively (see section 4.3.4).
4 Operation Data (= character string) can be sent to instruments connected via the serial RS232 interface. Make sure that the transmission parameters of the RS232 interface correspond to those of the connected instrument (see Configuration menu '>RS232 settings', section 4.2.1). Any letters, numbers and special characters can be chosen from the character set of the 766 IC Sample Processor. This function is suitable for instruments with Metrohm remote control language.
4.3 Methods 4.3.7 Process control START STOP LEARN HOLD RESET CLEAR QUIT With a method is started from the normal state. If there is no manual intervention or unexpected errors, the sample series is correctly processed and closed with the final sequence. The sample sequence is executed repeatedly according to the entry under 'number of samples', beginning with the sample tube that is defined as 'SAMPLE'.

PP Sample tube (6.2743.050; 11 mL) PE Bottle (6.1608.080; 300 mL) 010001 2 If desired, other user-defined racks can be delivered and defined in the instrument via PC software. Irregular arrangements of vessel positions are also possible. 4.5.
4 Operation Magnets inserted In this example the code is: 000110 Rack bottom view In order to assign a certain sample rack for different applications, certain properties or recognition data can be defined for up to 16 racks. This is useful when a certain beaker size or the size of the sample series or a certain course of processing is to be predefined in an application. 4.5.
4.5 Sample racks The rack Type serves for the assignment to a position table internal to the instrument, in which the positions of the sample tubes in the rack are defined in tenths of a degree (0-3599) of the full turning angle. The rack type is coded as Mxxx-y, whereby M stands for Metrohm-defined types. The placeholder xxx stands for the number of sample tubes in a rack. The numerical code y is a special code for the number of rows on a rack (0 = single-row, 1 = double-row, 2 = triple-row).
4 Operation 4.5.4 Special beakers Special beakers are reserved positions in a sample rack. 0 to 8 special beakers can be defined per rack. They can be placed under the needle during method processing for particular operations without interrupting or hindering the sample series run. Special beakers can be used in a sample sequence for rinsing the needle. Special beakers are placed under the needle with 'MOVE 1 : spec.1'.

5.1 Remote interface 5 Interfaces 5.1 Remote interface Peripheral instruments connected such as 732 IC Detector, 709 IC Pump, 752 Pump Unit, etc. can be controlled via the remote interface (25-pin socket). 14 lines (Output 0 – 13) are available for the emission signals. Lines 11 – 13 are used for swing head control. For receiving signals (e.g. the "ready" signal of the 732 IC Detector) 8 lines (Input 0 – 7) are provided. Line 7 is used for the swing head. 5.1.
5 Interfaces For the 766 IC Sample Processor, the output lines 11–13 and the input line 7 are occupied for the control of the swing head. These four lines are not continued in the plug and ignored, when further instruments are connected via the remote cable (see section 2.4). Various remote cables are available to use the specific functions of the individual instruments of the various Metrohm model lines (see section 2.4).
5.1 Remote interface Input lines 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 effective state of the input lines (for example, the status of the ready line of the 732 IC Detector). 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.

5.2 RS232 interface 5.2 RS232 interface 5.2.1 General rules for remote control The 766 IC Sample Processor is equipped with the comprehensive Metrohm remote control language, which allows full control over the instrument via an RS232 interface, i.e. the 766 IC Sample Processor can receive data from an external device or send data to an external device. The 766 IC Sample Processor sends 2×CR and LF as the terminator of a requested data block.
5 Interfaces 5.2.2 Call-up of objects A section from the object tree is shown below: Node 3 Language Node 2 Node 1 Prog Aux RSset Config Mode Node 0 & Root The following rules apply to the call-up of objects: Rules Examples The root of the tree is designated by ‘&’. For the call-up of an object, the nodes (levels) of the tree are marked by a point (.). For the call-up of the objects, as many characters as necessary to allow unambiguous allocation of the object suffice.
5.2 RS232 interface 5.2.3 Trigger Triggers initiate an action at the 766 IC Sample Processor, e.g. sequence start or data transmission. Triggers are marked by the introducer '$'. The following triggers are possible: $G Go Starts processes, e.g. starting the mode run or setting the RS232 interface parameters $S Stop Stops processes $Q Query Used to request all information from the current node in the tree forwards up to and including the values $Q.
5 Interfaces 5.2.4 Status messages To ensure appropriate control of an external control unit is possible, it must also be possible to request status conditions which provide information on the status of the 766 IC Sample Processor. The output of a status message is triggered by the trigger '$D'. Status messages consist of the global status, the detailed status and eventual error messages.
5.2 RS232 interface 5.2.5 Error messages Error messages ‘EXXX’ are appended to the status message and separated from this by a ‘;’.
