User Guide Landmark for Profibus Introduction 1.1 About this guide This guide gives the information necessary for you to operate a Landmark for Profibus Signal Processor. Information regarding installation is contained within the Installation Guide. 1.2 About the Landmark for Profibus Processor The Landmark for Profibus Signal Processor provides an accurate signal processing unit for a single LAND System 4 thermometer on a master-slave Profibus DP network. The Landmark for Profibus processor can be set and run entirely from the Profibus DP master. Profibus DP has three states in it’s normal operating cycle: User Parameterisation Configuration Data Exchange 1.2.1 User Parameterisation In ‘User Parameterisation’, a one-off download of the operating parameters of the processor is carried out, including: • Emissivity / Non Greyness •... -

Landmark for Profibus User Guide Installation and Removal 3.1 Fitting the Unit Onto a DIN Rail The LMP processor is designed to be mounted onto a standard DIN rail. To install the unit: Ensure that a suitable DIN rail (DIN EN 50 022) is available and installed c orrectly (refer to Appendix). Refer to Fig. 2.

Page 17: Profibus Dp Operation
User Guide Landmark for Profibus Profibus DP Operation This section gives details of how to apply the LMP to a Profibus DP System. It does not go into detail explaining Profibus DP. Further information can be found by visiting the designated website: www.profibus.com When the LMP processor is connected to a Land System 4 thermometer, the processor must be configured for use with that particular thermometer type. Profibus DP uses a ‘.gsd’ file as an electronic data sheet to allow the master processor to set up the operating parameters for the slave units attached to it’s network. 4.1 .gsd Files The Landmark for Profibus (LMP) is registered with the Profibus Nutzer Organisation (PNO) and has been designated with the special register number: LAND 0807. A .gsd file has also been allocated to this registration and is supplied on disk, with the processor. (LAND 0807.gsd). To allow access to the user parameters and cyclic data configuration of the processor, this .gsd file must be copied from the supplied disk to the gsd directory of the master system in use. 4.2 User Parameters User parameters are downloaded from the master system to the LMP, as a one-off at the start of Profibus operation. These user parameters are stored in a non-volatile memory within the LMP (if the LMP should lose power AND... - Page 18 Landmark for Profibus User Guide Page 12...
- Page 19 User Guide Landmark for Profibus Notes • If on-line access to a parameter is not required, set the LMP using the ‘User Parameters’ list. • A full, valid list of user parameters must be given, even if a particular parameter is not being used or is to be overwritten with cyclic data. • Ensure all parameters are within limits, as the LMP will reject any list containing ‘out of limit’ parameters.

Page 21: Configurable Cyclic Data
User Guide Landmark for Profibus 4.3 Configurable Cyclic Data In Configuration, it is possible to organise the continuous reading and writing of cyclic data. The most obvious candidate for cyclic data is the ‘Temperature’ value. However, within the LMP it is also possible to select most of the user parameters for cyclic adjustment i.e. without having to re-initialise the Profibus DP system. When adjusting a parameter cyclically (eg. emissivity), the value overwrites the parameter that was written during ‘User Parameterisation’. However, it will only be stored in volatile memory. If power is lost, the LMP reverts to the user parameter version of the parameter until data-exchange is re-established when the cyclic value will be used again. - Page 22 Landmark for Profibus User Guide Module Name Size Description Temperature & Status 2 words I/P Word 1 - Temperature: 16 bit unsigned value of temperature in units as per IRT type Word 2 - Status: Bit 0-2: Not used Bit 3: 1=Command IP active / 0=Not active Bit 4: 1=Under range / 0=OK Bit 5: 1=Under range / 0=OK Bit 6: 1=Unclamped ratio IRT obscured / 0=OK Bit 7: 1=Clipping in averager / 0=OK...

Page 23: Extended Diagnostics
User Guide Landmark for Profibus Notes • IRT Type, Time Function Type and Current O/P Parameters are NOT available as cyclic data • Any configuration MUST include the Temperature and Status module • Only one of any type of module is allowed • It is common for there to be mismatches in the order of bytes within I/P and O/P words. Should this happen, use the CyclicDataByteOrder User Parameter to reverse the order of the bytes within a word from the LMP. • The user MUST NOT configure cyclic data for inactive parameters i.e: 1) Emissivity is only configurable if a single colour IRT (M type) has been selected in the User Parameters; 2) Non Greyness is only configurable if a two colour ratio IRT (R type) has been selected in the User Parameters; 3) Peak Picker parameters are only configurable if Peak Picker has been selected in the Time Function Select User Parameter; 4) Averager Response Time parameter is only configurable if Averager has been selected in the Time Function Select User Parameter •... -
Page 24: Time Function Processing
Landmark for Profibus User Guide Time Function Processing 5.1 Peak Picker The Peak Picker function can be used to monitor the highest temperature measured by the thermometer. This feature is useful especially for moving targets and/or where the target is obscured partially e.g. a steel slab on a rolling mill where parts of the surface are covered with scale. The ‘clean’ area will be at the higher (i.e. true) temperature. The Peak Picker used in Profibus processors has the following features. Refer to Fig. 9. Threshold level: Temperature above which the Peak Picker is active, used in conjunction with the ‘ON’ and ‘OFF’ delay. ON delay: Time period between the temperature rising above the threshold level and the Peak Picker function switching on OFF delay:... -

The Averager time function can be used to ‘smooth’ the temperature output signal in relation to the temperature input. The averager response can be adjusted to suit your application. With a fast response speed, the temperature output signal tracks the input signal closely, any rapid fluctuations in the input are reflected in the output. -
