76. 9000 via the PROFIBUS interface the MLC9000 system must first be registered on the PROFIBUS network using the PROFIBUS network manager software A PROFIBUS gsd gse file is provided on a 3 5 Floppy disk with the PROFIBUS B240 BCM to allow the the MLC9000 to be registered onto the PROFIBUS network The latest MLC9000 gsd gse file is always available from our website at www westinstruments com Europe or www dancon com North America 7 4 VO SIZES AND MAPPING The I O requirements for PROFIBUS are dependent upon the number of Loop Controller Modules LCM s in the MLC9000 system At power up the BCM detects the the highest address LCM and sets the PROFIBUS I O data size accordingly For this reason when setting up the MLC9000 system on a PROFIBUS network gaps are not allowed L___ J If it is likely that additional LCMs will be added to the MLC9000 in the future ensure that other PROFIBUS devices mapped to the PLC do not use registers that may be required by these additional LCMs The maximum PLC I O requirements for the MLC9000 are 104 bytes input and 70 bytes output With older versions of the gsd gse file a device called Empty Slot was available to reserve register space for future expansion The amount of register space the empty slot reserved was for the single loop LCM making it unsuitable for systems that may require the 4 loop LCM in the future

172. vershoot is measured when the process variable value has dropped by an amount equal to the noise band If the process is noisy additional input filtering may be required to guarantee detection of the proper peak This overshoot is used together with the time to peak value to determine the optimum PID terms The stored overshoot is then updated in preparation for the next power up The computed PID terms are then used by the normal PID control algorithm to control the power applied to the process Note that on the next process power up when Easy Tune is enabled see Subsection 4 4 4 the maximum power is turned off when the process variable is below the setpoint by the new stored overshoot value It is expected that the subsequent overshoot above the setpoint will then be much less than previously NOTE Easy Tune is run from process power up and will always produce best results when used in this manner If the process has not cooled more than 5 of the input span see Subsections 4 1 10 amp 4 1 11 below setpoint or by more that the stored overshoot value below setpoint Easy Tune will not operate and PID terms and stored overshoot value will be unchanged In processes with a large overshoot this could lead to confusion as to whether Easy Tune is operating correctly or not B 2 PRE TUNE Pre Tune is initiated either at power up see Auto Pre Tune Subsection 4 4 6 or manually using the Pre Tune parameter Pre Tune can be initiated at any
