## **NRGC** 

## **NRGC** 

## **NRG controller with Modbus RTU over RS485** 

## **Main features** 

- **Communication interface.** The NRG controller bridges the field level devices to the control level to allow exchange of data in real-time with the NRG solid state relays. 

- **Reduced maintenance costs and downtime.** Use of real-time data for prevention of machine stoppages during operation. 

- **Good quality products and low scrap rates.** Real-time monitoring allows timely decisions for better machine and process management. 

- **Reduced efforts in troubleshooting.** A number of faults can be distinguished to facilitate and reduce troubleshooting time. 

- **Fast installation and set-up.** The solid state relays on the BUS are configured by AutoConfiguration for fast set-up and prevention of incorrect settings. 

- **Compact dimensions.** One controller with a product width of 35 mm can handle up to 32 RG..CM..N or 48 RG..D..N NRG solid state relays. 

## **Description** 

The **NRGC** is the NRG controller in the NRG BUS chain. 

The **NRGC** interfaces directly with the main controller of the system through Modbus RTU on an RS485 interface. Each **NRGC** in the system is identified by a unique Modbus address that can be set either manually via a front selector switch that allows only Modbus addresses 1 to 15 or through dedicated registers for addresses 1 to 247. The default Modbus communication settings can also be modified via dedicated registers. 

The **NRGC** acts as a master of the respective NRG BUS chain when it is requested by the main controller to carry out actions on the specific NRG BUS chain. Otherwise, the **NRGC** is just a facilitator of the communication between the main controller and each individual **RG..N** solid state relay in the system. 

The **NRGC** needs to be supplied with 24 VDC. It is equipped with a configurable digital output that is set as an **NRGC** alarm indication as the default setting. LEDs on the front facade give a visual indication of the status of the NRGC, of any ongoing communication with the main controller (COM) and the RG..Ns on the BUS chain (BUS) and of any alarm condition related specifically to the **NRGC** . 

Specifications are noted at 25°C unless otherwise specified. 

## **Applications** 

Any heating application where reliable and precise maintenance of temperatures is crucial to the quality of the end product. Typical applications include plastic machinery such as injection machines, extrusion machines and PET blow moulding machines, packaging machinery, sterilisation machinery, drying tunnels and semiconductor manufacturing equipment. 

## **Main function** 

- Communication interface: Modbus over RS485 

- Connects up to 48 **RG..D..Ns** or 32 **RG..CM..Ns** 

- Selector switch for Modbus addresses 1-15 (Modbus addresses 1-247 through comms) 

- Supply voltage 24 VDC +/-20%

## **System Overview** 

The NRG is a system consisting of one or more BUS chains that enable communication between the field devices (such as the solid state relays) and the control devices (such as the machine controller or PLC). 

Each **NRG BUS** chain consists of the following 3 components: 

- the NRG controller 

- the NRG solid state relay(s) 

- the NRG internal BUS cables 

The **NRG controller** is the interface to the machine controller. It acts as the master of the BUS chain when performing specific actions on the respective BUS chain, and acts as a gateway for the communication between the PLC and the RG..N solid state relays. It is not possible to operate the NRG system without the NRG controller. 

The NRG controllers available are: 

- **NRGC** 

- The NRGC is a NRG controller with a Modbus RTU interface over RS485. The NRGC is addressed via the assigned Modbus ID (from 1-247). In a NRG system operating on Modbus it is possible to have 247 NRG BUS chains. 

## **• NRGC-PN** 

NRGC-PN is a NRG controller with a PROFINET communication interface. The NRGC-PN is identified by a unique MAC address which is printed on the facade of the product. The GSD file can be downloaded from www.gavazziautomation.com 

## **• NRGC-EIP** 

- NRGC-EIP is a NRG controller with an EtherNet/IP communication interface. The IP address is provided automatically 

- via a DHCP server. The EDS file can be downloaded from www.gavazziautomation.com 

- **NRGC-ECAT** 

- NRGC-ECAT is a NRG controller with an EtherCAT communication interface. The ESI file can be downloaded from www.gavazziautomation.com 

## **• NRGC-MBTCP** 

NRGC-MBTCP is a NRG controller with a Modbus TCP communication interface.

## **System Overview - continued** 

The **NRG solid state relay** is the switching component in the NRG system. Each **RG..N** integrates a communication interface to exchange data with the machine controller (or PLC). The available RG..Ns that can be used in an NRG system are: 

## **• RG..D..N** 

The RG..D..N are solid state relays for use in an NRG system having the communication interface only for real time monitoring. Control of the RG..N is done via a DC control voltage. It is possible to have maximum 48 **RG..D..Ns** in one NRG BUS chain. 

## **• RG..CM..N** 

The RG..CM..N are solid state relays for use in an NRG system having a communication interface for control of the RG..N through the BUS and for real time monitoring. It is possible to have a maximum of 32 RG..CM..N  in one NRG bus chain. There are two variants of the RG..CM..N: 

**RGx1A..CM..N** - the solid state relay with zero cross switching 

**RGx1P..CM..N** - the solid state relay with proportional switching. 

For a review of the features available in both variants refer to the table below:

It is not possible to mix RG..D..N and RG..CM..N in the same BUS chain. 

The **NRG internal BUS cables** are proprietary cables that connect the NRG controller to the first RG..N in the NRG BUS chain and respective RG..Ns on the BUS. The internal BUS terminator, provided in the same package with the NRG controller, shall be plugged to the last RG..N in the NRG BUS chain.

**Main features** • Cables available at various lengths to provide the internal BUS of the NRG system • Cables terminated at both ends with a microUSB plug • Connects the NRG controller to the RG..N solid state relay and respective RG..N solid state relays l ~~g~~ **Description** > The **RCRGN** cables are proprietary cables that must be used with the NRG system for the internal BUS. These cables connect the NRG controller to the RG..N solid state relays and respective RG..N solid state relays. 

The RCRGN... are 5-way cables carrying the communication, supply and autocofiguration lines. By means of autoconfiguration, the RG..Ns are assigned a unique ID based on the physical location and hence internal BUS wiring sequence when an autoconfiguration command is sent to the RG..Ns.
