Features

To bring Ethernet from the office to the system field requires a number of enhancements; the most important is real-time capability. Depending on the application, a marketable industrial Ethernet must handle safety applications or the entire range of drive technology, right up to synchronous motion control with cycle times of less than a millisecond.
You can achieve this using a clever distribution of protocols via the OSI layered system structure. This results in many solutions. One of the most common is the open standard, PROFINET, which also provides a great deal of investment protection. Existing field bus systems such as Profibus DP, Profibus PA, AS interface and interbus can be included in the existing field devices without the need to make changes.

The UMG 96RM-PN is equipped with two Ethernet interfaces that conform to PROFINET IO-IRT and an integrated switch. The familiar line topologies are used to display the structure of the field bus technology in a way that complies with standards. Parameters can be set and configuration carried out completely in the Step 7® environment or the TIA portal. All measured values are displayed directly in the PLC's process data channel. Its digital inputs and outputs can be used via both Modbus and PROFINET. Two analogue inputs are available for 0-30 mA or to capture temperatures. A separate 5A current measurement channel can monitor the neutral conductor, for example.

All relevant measurements can be displayed on the device's own homepage. A REST interface enables measured values and configuration parameters to be queried from the HTTP interface. A highlight is integrated residual current monitoring (RCM), which can be used to detect insulation faults at an early stage.This increases the system availability and reduces the risk of fire.

Energy data capture has become increasingly important in recent years. This is less due to the cost factor itself, but more due to realising that only fine-tuned and highly temporally resolved energy data capture can enable the desired savings. To do this, the measurement technology must be integrated into existing systems – even in ongoing operation where possible.

PROFINET is ideal for this task as this standard enables it to be integrated into existing field bus systems such as Profibus DP, Profibus PA, etc. easily. This also allows measuring devices such as the UMG 96RM-PN to be integrated into the field bus level without complications.

Simple installation reduces the costs. Furthermore, migrating from centralised to decentralised structures is possible. Additional infrastructure components are not required, as the UMG 96RM-PN already has a switch and two PROFINET interfaces on board and, therefore, enables line structures to be set up.

The UMG 96RM-PN is certified for PROFINET and is suitable for using PROFIenergy. A PROFINET certificate attests to a response that conforms to standards in accordance with IEC 61158 within a PROFINET network and, therefore, guarantees a high standard of quality.

PROFIenergy is a profile for energy management in production systems, which is based on PROFINET. Energy consumers within the system can, therefore, be controlled using open and standardised commands. Using PROFIenergy means that external, hard-wired systems are no longer required.
