4. 2 of this manual The 1309 accepts job headers in both upper and lower case characters The Data Field The data field contains further information specific to the interface job defined by the job header The data field is separated from the job header by a space character SP or a comma In the following examples the separator will always be the space character represent ed by the symbol _ The data field will normally contain a numerical value For example OPEN_SAMPLING_VALVE _2 Some jobs may require more than one item of data In this case the data is given item by item separated by commas For example OPEN_SAMPLING_VALVE _2 3 4 BE1285 15 1309 Multipoint Sampler LumaSense Technologies A S Page 23 of 42 Chapter 3 Numerical data for interface jobs sent to the 1309 can be in NR1 NR2 or NR3 form This is a format for describing how the numerical data is represented for example NR1 data 250 number without decimal fraction or exponent NR2 data 249 85 number with decimal fraction without expo nent NR3 data 2 499E 2 number with fraction and exponent Generally any of these data formats can be used unless specifically stated otherwise in the interface job overview given in section 4 2 The number of characters in the non exponent part of the data field must not be greater than 8 Job Terminators BE1285 15 Each interface job must have a terminator signified by Te in Fig 3 1 whic
5. The 1309 s functions are controlled over the IEEE IEC interface using a range of commands and data requests each of which is specific to a particular function or item of data These commands and requests are known as interface jobs This section describes the structure of the in terface jobs used to control the 1309 Further details about the IEEE IEC interface of the 1309 are given in Chapter 4 of this manual Syntax for Interface Jobs Fig 3 1 shows a diagram representing a single interface job sent from the system controller to the 1309 Each constituent part of the interface job is explained below 1309 Multipoint Sampler LumaSense Technologies A S Page 22 of 42 Chapter 3 PP y al Job Header y Data 8924946 Job Headers The job header specifies the function you want the 1309 to perform It consists of one or more words The ASCII underline character _ is used to separate individual words in the job header For example OPEN_SAMPLING_VALVE A hyphen or a full stop can also be used to separate words in the job header The words making up the job header do not need to be sent in full to the 1309 they can be shortened to a code form for example OP_SA_VALVE O_S_V The minimum code for each job header is usually the first character of each word in the job header This is written in bold characters in the list of interface jobs given in section 4
6. This job reads out an 8 bit byte the Warning Flags which gives infor mation about error conditions which affect the efficient operation of the 1309 The 1309 is still able to operate but the error should be rectified as soon as possible The Warning Flag byte is shown in Table 3 4 Table 3 4 The 1309 s Warning Flags byte WARNING FLAGS Bit no Dec Value Flag Description 1 1 Reset Done Flag 2 2 Temperature Flag 3 4 Power Fail Flag 4 8 Not used 5 16 Not used 6 32 Not used 7 64 Not used 8 128 Not used Warning Flags are set when either the 1309 s self check procedures or the Check System interface job identify an error condition This in turn sets bit 6 of the Status Byte generating a service request if enabled to indicate that an error condition exists The Warning job can then give more information about the cause of the error condition Example Warning lt LF gt Outputs the Warning Flags from the 1309 A 1 indicates that the flag is set a 0 indicates the flag is not set The conditions which cause the Warning Flags to be set and the appro priate action to be taken are dealt with in turn below Reset Done Flag Indicates that the 1309 has completed a reset following either the Re set System interface job section 3 6 2 or switching on the 1309 This flag is reset when the Warning Flags are read out from the 1309 Temperature Flag BE1285 15 Is set when the int
