1、Designation:E 1989 98(Reapproved 2004)Standard Specification forLaboratory Equipment Control Interface(LECIS)1This standard is issued under the fixed designation E 1989;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last
2、 revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers deterministic remote control oflaboratory equipment in an automated laboratory.The labor-intensive p
3、rocess of integrating different equipment into anautomated system is a primary problem in laboratory automa-tion today.Hardware and software standards are needed tofacilitate equipment integration and thereby significantly re-duce the cost and effort to develop fully automated laborato-ries.1.2 This
4、 Laboratory Equipment Control Interface Specifica-tion(LECIS)describes a set of standard equipment behaviorsthat must be accessible under remote control to set up andoperate laboratory equipment in an automated laboratory.Theremote control of the standard behaviors is defined as standardinteractions
5、 that define the dialogue between the equipmentand the control system that is necessary to coordinate opera-tion.The interactions are described with state models in whichindividual states are defined for specific,discrete equipmentbehaviors.The interactions are designed to be independent ofboth the
6、equipment and its function.Standard message ex-changes are defined independently of any specific physicalcommunication links or protocols for messages passing be-tween the control system and the equipment.1.3 This specification is derived from the General Equip-ment Interface Definition developed by
7、 the Intelligent Systemsand Robotics Center at Sandia National Laboratory,the Na-tional Institute of Standards and Technologies Consortium onAutomated Analytical Laboratory Systems(CAALS)High-Level Communication Protocol,the CAALS Common Com-mand Set,and the NISTIR 6294(1-4).2This LECIS specifi-cati

12、,1.4.17 Independent power-up order,and1.4.18 Safe start-up behavior.2.Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 command messagecommunication from the TSC tothe SLM that is being controlled.Receipt of this messagecauses a state transition in an interaction.2.1.2 device capab
13、ility datasetdata file that contains all ofthe SLM-specific information required for the TSC to interactwith the SLM(2).This includes definitions of the arguments ofthe standard commands and events,estimates of processingtimes in states,and SLM specific interactions.Material inputand output ports an
14、d support services are also defined.2.1.3 errorinfrequent,unplanned event that makes thecurrent goal of the SLM unachievable given the systemresources,the state of the system,or the absence of aguaranteed,alternative plan.(This definition is distinct fromany other ASTM standard definition of error.)
