RP ru ob dr ui k c t s U nSt ie mr ro uc bo rd i ek p Simocode intelligent motor management system Promoting Energy Efficiency With easy integration to PCS 7, the Simocode intelligent motor management system enables dynamic monitoring of motor performance and the opportunity to enhance energy efficiency in the plant. Energy consumption is the second largest operating expense in a process plant, after raw materials. And studies have shown that more than sixty percent of that energy is used to operate motors. Hence, optimizing motor energy consumption is a logical starting point in any energy cost reduction initiative. In the traditional process plant, it has not been economical to hardwire all of the operating data from individual motors back to the process controller, which makes it almost impossible to determine the energy consumption for different parts of the process. This information gap prevents plant operators M o t o r m a n a g e m e n t s y s t e m S i m o c o d e p r o Simocode pro (Sirius Motor Management and Control Devices) is the flexible, modular motor management system for constant speed motors. By means of a Profibus DP interface it can easily be linked to a higher-level automation system. Simocode pro implements all motor protection and control functions, provides operational, diagnostic and statistical data and organizes the communication between automation system and motor feeder. In addition, Simocode meets all the requirements for future-proof power management. Simocode pro is divided into two device series with different levels of functions: 3 Simocode pro C (Compact): the compact motor management system for direct on-line starters and reversing starters 3 Simocode pro V (Variable): the variable motor management system with an even greater range of functions including voltageand power monitoring The system also includes software tools for plant configuration, device parameterization, diagnostics and plant documentation. from scheduling partial shutdowns to improve energy efficiency or from taking advantage of the various incentives that electric utilities offer to balance demand. But today’s new class of DCS, exemplified by the <strong>Siemens</strong> PCS 7, not only provides regulatory control of processes, but can integrate high speed devices to enable dynamic monitoring of motor performance and, hence, much more sophisticated management of energy consumption. Simocode spells smart Simocode is an intelligent motor management system that can be added to the MCC motor bucket to make it “smart”. Hardwired circuitry running to the various motors across the plant is replaced with just one fieldbus cable and the compact tool provides a high level of protection, monitoring and control. For example, the control circuit can be “rewired” via a mouse click, and eliminating conventional relays saves space and reduces wiring expenditures. In particular, with Simocode, a high degree of detail on the status and performance of each motor component is provided, including motor current, direction, phase and overload status. This information can be sent up to the PCS 7 via a single Profibus DP cable. Having access to comprehensive data on motor activity in the process plant provides a number of benefits: Productivity improvement – engineers can modify operating parameters, analyze performance, and reset faults of an individual MCC bucket directly from the control room; downtime minimization – an unusual condition such as excessive current draw can be reported in the DCS, allowing operators to 12 ideas singapore | 2008

New and updated And now, the latest release of the Simocode pro motor management system features a number of new components, accessories, functions, plus an update of the parameterization software. The operator panel with display provides for indication of current measured values, diagnostic data and status information directly at the control cabinet. Selecting predefined profiles, the user can determine the values to display during normal operation. As for functions, two new logic blocks can do arithmetic operations and adjust, calculate and convert analog values such as temperature, allowing measured values to be transferred to the DCS in predefined units. An addition to the statistical data provided by Simocode is “motor power consumption” (in kWh), which allows users to quantify power consumption of motor feeders. An update of the Simocode ES parameterization software provides multilingual online help and trend indication of the current curve shape (of up to five measured values). These new functions can be applied via a service pack for previously installed versions of Simocode ES. p info contact www.siemens.com/simocode wahseng.liew@siemens.com ideas singapore | 2008 13
