RHAA007(Driver Name): (Port Name) Received data has been framing error

Error Details
The error message [RHAA007(Driver Name): (Port Name) Received data has been framing error] appeared on the GP3000 screen.

Causes

This error occurs when the data the GP received is different from the data the device/PLC sent.
■ The cause could be a lack of receiving data.
■ The cause could be a noise or a loose connection.

Actions
1. Check if the data length and parity bit settings of the host side and those of the GP side are the same, if the Memory-Link method is used.
→ Communication Settings on the GP unit
→ Communication Settings in GP-Pro EX
2. Place the cables away from noise sources (such as a welding machine, an inverter or a motor) by rewiring the cables, or try noise suppression such as attaching a ferrite core.
3. Check the cable soldering, electric continuity, and if the connector is installed properly.

NOTE
For detailed explanations of the communication settings and parameters, please refer to the Device/PLC Connection Manual.
