Interface for a Local Operator Station-ABB

Date: May 07, 2025 Views: 903

　　Advant Controller 160 Processor Modules include an asynchronous serial interface (Com B), which is intended only for communication with a PC-based Human Machine Interface (HMI) package (3rd party product). In Advant Controller 160 data is exchanged, with e.g. the HMI package, by means of PARDAT elements. The supported communication protocol on this serial interface is the MODBUS I protocol. The serial interface on the CPU can only be used as a slave on MODBUS.

　　The number of MODBUS I commands that can be exchanged via the serial interface is depending on the type of command and also on the load of the CPU. For performance estimation the figures for Advant Controller 110 within Advant OCS Product Guide as worst case figures can be used.

　　Cycle and Scan Times

　　An Advant Controller 160 application program consists of one AMPL program (PCPGM) which can be further divided into a maximum of 31 (PM665: 63) execution modules (CONTRM, MASTER) or sequence modules (SEQ). Note that SEQ and STEP cannot be used with redundant processing. Instead GRC and P_STEP can be used. Different cycle-times may be assigned to the execution modules so that the AMPL program can include both fast and slow control functions. Cycle times can be chosen from the range 2 ms to 20 s in steps of 2 ms. For applications with redundant Processor Modules cycle times smaller than 10 ms are not applicable.

　　For triple redundant configuration maximum cycle time is 1 second.

　　Control tasks with shorter cycle times always have a higher priority than those with longer cycle times. The execution order of modules with equal cycle times can be selected explicitly. Activation once at start can be chosen by the CONTRM’s call parameter C2.

　　I/O Scanning

　　The scanning of I/O modules is directly related to the cycle time of the execution module.

　　Each execution module reads its inputs before execution of its AMPL elements. This guarantees a consistent image of the process signals. After execution of the AMPL elements, the module writes the calculated results to the outputs.

　　CPU Load Calculation

　　To determine the CPU load for an Advant Controller 160, the maximum load values available for the application program as shown in Table 6-9 must be considered.

　　CPU Load Calculation, Data Set Communication

　　The OCS Product Guides provides load data from Data Set communication for Advant Controller 110. These data can be used for PM640, PM644, PM645, and PM646 if divided by 3. For PM665 this has not been measured yet.

　　Memory Requirements

　　1 Mbyte of memory is available for the application program. For a rough calculation of the application memory requirements, the following table can be used.

　　Chapter 7 Environmental Immunities

　　Environmental Considerations

　　General

　　Advant Controller 160 is designed for a demanding industrial environment. Alternative cabinets is available for different degrees of protective rating (IP21, IP41, IP54). Interference from electrical sources is suppressed by a suitable solid design and particular installation rules. The building where the system is to be stored or installed should provide an environment such that established environmental conditions are not normally exceeded.

　　A hardened enclosure protects the printed circuit boards from mechanical and electrostatic damage and from electromagnetic interference. The equipment complies with the EC directives 89/ 336/EEC on electromagnetic compatibility, 73/23/EEC and 93/68/EEC on low-voltage apparatus. Limit values are given to: Corrosive gases, Temperature, Vibration, Moisture, Electro-Magnetic Compatibility, etc.

　　For further information about the environmental immunity, please refer to the Environmental Immunities chapter in the Advant OCS with Master Software, Overview Product Guide.

　　Temperature

　　It is important to note the temperature within cabinets and in the surrounding environment and atmosphere. Lower temperatures mean increased system reliability and availability

　　The lives of wet, electrolytic capacitors and most semiconductors are greatly reduced if the maximum permitted temperatures are exceeded.

　　To avoid overheating, when ambient temperatures are high, take into consideration the heat dissipated in the cabinet. This is particularly important with sealed cabinets (IP54) with considerable number of circuit boards and ambient temperatures at levels approaching 40°C. It might be necessary to mount heat exchangers on the cabinet to bring down the temperature to levels below limits given in the environmental data sheet.

　　The different hardware modules in the controller and the I/O system have different outputs of heat. Accurate calculation of the heat produced by the system requires knowledge of the modules and the work cycle.

　　Maximum permitted temperature above the subracks in the cabinet is 55°C.

　　Chapter 8 Ordering

　　Price List Structure

　　Depending on the desired I/O configuration one or several price books and price lists must be used when ordering an Advant Controller 160 with local S600 I/O, distributed S800 I/O or additional hardware modules to support enhanced features, e.g., burner management, turbine control, or safety applications.

　　Advant Controller 160 Version 2.1 (3BSE020695/B)

　　Price Book AC 55/70/110/160, AdvaSoft and OPC Server (3BSE001780/L).

　　See this Product Guide.

　　S800 I/O Version 3.2 (3BSE014394/D)

　　Price Book S800 I/O (3BSE020696/A).

　　See S800 I/O Product Guide (3BSE015969R301).

　　Spare Parts (3BSE001783/K)

　　Price Book AC 55/70/110/160, AdvaSoft and OPC Server (3BSE001780/L).

　　Assembled Delivery or Loose Part Delivery

　　The item Assembly and test in Table 8-1 determines if the controller shall be mounted in cabinets or not. If this item is not ordered the delivery will be a loose part delivery

　　Note also that in Table 8-1 the items for CE-marking are different for an assembled delivery and for a loose part delivery

　　Loose Part Delivery and CE-marking

　　If an Advant Controller 160 is ordered as a loose part delivery and the intention is to mount the equipment in other cabinets than RM500, certain considerations must be taken to make it follow the provisions of the EMC Directive 89/336/EEC, Low Voltage Directive 73/23/EEC, and 93/ 68/EEC.

　　• The cabinet or series of cabinets mounted side by side must be radio-proof.

　　• Protection against line conducted radio emissions is obtained by means of a mains net filter placed in the cabinet close to the incoming mains cable.

　　• Communication cable shields must have a capacitive grounding at the point where they enter the cabinet.

　　The conditional EC-Declaration of Conformity, which accompanies the loose part delivery, must be signed by the person responsible for assembling the controller in cabinets.
