Flender/Flender Gear Units/Bevel-helical speed reducers B4
transmitters using HART protocol. The configuration of the control systems application software shall be above to be modified with regards

to the process controllers (logic, adjustments, interlocks, alarm pages, etc). The use of the modified configur ation however shall not

require the suspendi ng of control and supervision fun ction of the node or nodes involved in the modifications. .

Control System Structuring / Configuration / Tuning Facilities Structuring / configuration and tuning facilities shall be provided for structuring /

modification, stor ing / loading, testing, tuning, monitoring etc. of all the microprocessor based cont rollers of the control system. It shall be possible to configure the system with ease without any special knowledge of programming or high level languages. Control strategy shall be implemented using familiar and conventional automation function blocks (sof tware implemented). Whichever any cha nges in configuration is done, shall be recorded and modified. Configurat ion shall be available for pri nting and documentation and shall be store in non-volatile memory. The entire system configuration, tuning / fixed par ameters shall be documented an printing in form of function diagrams and lists respectively. On-line tuning of the control loops shall be possible without ausing any disturbance in the execution of the control loops. Provision to retrieve on immediate and long term basis the system configurat ion, data base etc. on some device such as CD shall be included. Facility shal be provided to reload / down load the system or controller module from the lready stored data, on-line. II. HMI Program Development / Modification The EWS shall be able to provide programme development / modification to achieve various functions including development modification an testing of software of HMI; generation and modification of graphics, Logic , Historical Storage & Retrieval system funct
