Real Time Automation 490NBX Overview
The RTA 490NBX exchanges raw Ethernet TCP data with Allen-Bradley PLC tags. It targets devices such as barcode readers, scales and displays that communicate through TCP, using browser-based configuration to establish the device and PLC mapping.

Review Summary

A useful candidate when an existing TCP device needs a defined data path to an Allen-Bradley controller. The application still needs a message-format and transaction contract; receiving a string is not the same as accepting a valid production result.
