Can I use the RNA for discrete applications?

The RNA-1845 is an analog specific device and cannot be used for discrete applications. The RNA-1845D is designed for discrete applications and will be available in the near future.

How can I get my logged data into my historian or SQL database?

The RNA-1845 provides a CSV (Comma Separated Variable) formatted file which can be easily used in an historian, an SQL database, in Excel, or any other system capable of accepting a CSV formatted file.

How do I give the RNA-1845 an IP address and make it accessible on my network?

The RNA-1845 is capable of automatically assigning itself an IP address and making itself accessible on your network via either DHCP or a statically assigned IP address. The RNA-1845 looks first for a DHCP server to get its IP address, and then if none is found will default to a specified static IP address from which it can be accessed for re-assigning the IP address manually.

I don’t have any PoE switches in my facility; can I still use the RNA-1845?

The RNA-1845 is designed to utilize PoE, or an external 24VDC power source for its power. Media converters or midpoints can be added to traditional Ethernet networks that enable PoE.

What are the requirements for the PoE switch when using PoE with the RNA-1845?

The RNA-1845 is designed per IEEE 802.3af standards. As long as your switch is made to work with these specifications you can use it with the RNA-1845.

Can I use the RNA-1845 with a wireless Ethernet radio?

Yes. The RNA-1845 can be used with any Ethernet capable transmission system; Wireless radio (licensed or unlicensed), Cellular system, Satellite system, and or ATM.

My plant utilizes a fiber optic Ethernet backbone; can I use the RNA-1845?

Yes, with the use of a copper to fiber capable switch, or converter. The native Ethernet connection on the RNA-1845 is a copper connection.

Can I use the RNA-1845 to control a proportional valve?

No. The RNA-1845 is designed to provide monitoring data only. The RNA-2020 will provide control capabilities and will be available mid to late 2009.

How does the RNA-1845 handle security?

The RNA-1845 has three levels of security built into the device.

1. User Access - View data only

2. Admin Access - View and Change data

3. Factory Access - Factory ONLY

RTG recommends that the RNA sit on the inside of a traditionally secured network, including router and firewall security. The RNA-1845 security levels are not meant to provide global security for the device and or device network. In most cases your plant network segment has already been secured and is ready for the RNA-1845. In new and or unique applications, it may be necessary to involve IT resources.
