4. Overview
4.1 Introduction
This document is written for technicians who must configure the cobas c 111 interfaces in
the environment of a lab. Depending on the type of host system and workflows in the
laboratory, the cobas c 111 host interface offers a set of configurable features. The assigned
reader should have basic knowledge of laboratory terms and workflows.
To understand all the details of the cobas c 111 host interface it is important to know the
context of the LIS interface between the cobas c 111 and the host, e.g. a Laboratory
Information System.
4.2
4.3 System Overview
Before discussing the host communication’s working principle, it is important to understand
the basic architecture of the system. This section provides an overview of the architecture
and discusses some specialized items of interest pertaining to the analytical system.
•The Sample Area is the place where the sample tubes are kept for processing.
•The Pipetting Unit is responsible for collecting the reagent and sample fluids, filling
them into the reaction cuvette and mixing of the various fluids.
•The LCD with a Touch Screen interface allows operator interaction with the system,
such as entering orders, displaying results and changing configuration settings.

4.4 System Information
4.4.1 Sample Carriers
The cobas c 111 instrument has a direct sample reception area and does not use or
support separate sample carriers such as racks.
4.4.2 Samples
The sample area can accommodate various types of sample tubes and cups. A sample must
be identified prior to positioning at the sample area. Containers that are introduced without
prior identification will be refused and will not be processed. During analysis, the analyzer
retrieves the identification of a sample from its memory and matches it to the corresponding
sample position, then analyzing it according to the test orders defined for that sample.
•Standardized material used for calibration
•Control material used for quality control
•Patient samples
4.4.3 Sample Type
The cobas c 111 system database does not support the definition of ‘Sample Types’,
therefore a specific ‘sample type parameter’ is not available in this host interface protocol.

4.4.4 Repeat / Rerun
Repeating an order will just do the same basic processing again.
Rerunning an order means to repeat according to the settings given in the application
configuration, such as predefined dilution factors.
Note: For easy reading only the term ‘Rerun’ instead of ‘Repeat / Rerun’ will be used in this
document.
4.4.4.1 Manual Rerun
The operator can manually ask for a Rerun.
To do so, the operator has to display the result in question and ask for a Rerun. This action
can also be initiated via the host. Once the sample is recognized by the system (i.e. already
present or re-inserted by the operator) the measurement will be initiated.
4.4.4.2 Automatic Rerun
Automatic Rerun is not supported on cobas c 111 instruments.
4.4.5 Sample Number and ID modes
The analyzer can be operated in one of two modes for identifying samples:
•ID Mode, using barcoded samples
settings: Utilities/Configuration/Workflow/Sample Barcode = on
•Sample Number Mode, each sample number is manually entered by the operator
settings: Utilities/Configuration/Workflow/Sample Barcode = off
The most common mode used is ID Mode, which also allows processing of samples that
have damaged, unreadable or missing barcode label.
For all following described Sample ID Handling modes you can use ID Mode or Sample
Number Mode
4.4.5.1 Order ID = Sample ID
Setting: Utilities/Configuration/Workflow/Sample ID handling -> Order ID = Sample ID
The user can switch between ‚ID Mode’ and ‚Sample Number Mode’ during standby without
clearing the database, but switching is strongly discouraged.
Generally, once a mode is decided upon, it should not be changed.
The sample identification item (Sample ID) however remains the same in both modes.

cobas c 111
Host Interface Manual
Version
2
.1
13 / 93
In this mode the Order ID is equal to the Sample ID. The sample number is given by the
operator while placing the sample on the system.
4.4.5.2 Independent ID
Setting: Utilities/Configuration/Workflow/Sample ID handling -> Independent ID
In this mode the Sample ID and the Order ID are not connected to each other and could be
different. Sample ID is given by the operator. Order ID can be given by the operator or the
system increments automatically the Order ID.
Setting for automatic Order ID increment: Utilities/Configuration/Workflow/Auto Order ID -
> On
4.4.5.3 Grouped Sample ID
Setting: Utilities/Configuration/Workflow/Sample ID handling -> Grouped Sample ID
In this mode the Sample ID and Order ID are identical. For a given patient, the sample ID is
used all the time. A three digit number is appended and automatically increased with each
new order.
This mode is used to provide a patient ID centric behavior for cobas IT 1000 interface
connected systems. In this mode the Sample ID entered is extended on c111 (3 char unique
extension per sample ID), to provide a unique sample ID for the system, when there is a
need to handle samples with identical barcodes or manually entered IDs.
The total number of characters (including separator and number) is 23.
The extension is done whenever the system is configured in that particular mode. The
extended ID is then processed by the system in the same manner as in other modes.
To complete the NPT ID Mode the host protocol will send the part of the sample ID which
has been entered in the P-Record simulating a patient ID. The complete extended sample
ID is still reported within the O-Record as sample ID field.
It is important to know that even by introducing this P-Record content the system will not
maintain patient relevant data, neither will it consolidate data based on P-Queries or send
multiple O-Records belonging to a specific P-Record.
4.4.6 Working Mode
The Working Mode defines the way you select tests when defining orders.
4.4.6.1 Manual
Settings: Utilities/Configuration/Workflow/Working Mode -> Manual
During order definition, the test selection screen is displayed, allowing you to select the
tests or to make changes to the selection.
After measuring the sample the results are uploaded to the host system.

6.1 Communication methods
cobas c 111 instruments support real-time communication and batch communication for
test ordering and analytical data upload.
6.1.1 Automated Real-Time Communication (REAL)
Real-time communication refers to a communication model where the reception of a
sample on the system triggers an inquiry for test orders from cobas c 111 instrument to
host. The host may now download the known orders for this specific sample order (also
known as Host Query Mode).
The relationships between real-time communication functions and types of samples are
shown in Table 1. The following are the details regarding communication procedures and
communication functions.

6.1.1.1 Sample Introduction
Samples (tubes and cups) are placed directly into one of the sample carrier slots of the
cobas c 111 instrument. (Sample Area)
6.1.1.2 Sample Identification and Test Ordering
A sample is identified by the sample ID either read via barcode reader or the number given
by the operator. On cobas c 111 instruments a sample is never referred to by a position.
The system looks for test orders for each sample, depending on configuration settings. Test
orders can come from:
•The host prior to testing
•The host as a result of a ‘Test order inquiry’ initiated by the analyzer
•Manually programmed test orders on the analyzer by the operator
6.1.1.3 Sample Aspiration
The aspiration of sample will take place at the position in the Sample Area. Once all sample
aspirations have been done, the sample can be removed without disturbing the perfor-
mance of the system.
