Profinet Brings Many Benefits to Motor Management System
Siemens Industry Automation Division has expanded its SIMOCODE pro motor management system, adding a Profinet interface to the basic unit. Linking SIMOCODE pro to higher-level automation systems via Ethernet allows new functions to be provided for motor diagnostics, control and protection. Additionally, integrating PROFIenergy improves energy management.
Siemens new SIMOCODE pro motor management system includes a SIMOCODE pro V Profinet basic unit with two RJ45 interfaces, allowing the system to connect to higher-level controllers such as Simatic S7 or to control systems such as Simatic PCS 7.
Profinet can be used to provide media redundancy functions which ensure that a connection is maintained within a network with ring topology, even if one communication channel fails. This helps to increase the availability, resulting in increased productivity of the entire plant.
Profinet compatibility gives users better diagnostic and control functions while also simplifying communication between higher-level plant control and drive systems. SIMOCODE pro features integrated web diagnostics, as well as server for OPC UA, the multi-vendor communication standard in automation.
With the aid of an Internet browser, all diagnostic and service data, values and statistics relating to the motor starter can be called up from anywhere via a network connection and the web server. This means increased flexibility for the user. The integrated OPC UA server allows this data to be called up from the higher-level SCADA system via HMI panels at the field level. Users can also have their diagnostic data shown in a customized display adapted to their application. A further advantage of the OPC UA server is that control signals can be transmitted to the control system via a secure link. That lets users monitor and control the drives more effectively while also improving protection.
PROFIenergy has also been integrated into the new basic unit for SIMOCODE pro with the Profinet interface. The motors are controlled centrally via Profinet and, for example, can be shut down during breaks. The measured values and status information can also be called up via the PROFIenergy protocol, thus enabling efficient energy and load management. This considerably reduces the plant’s energy requirements and costs.
