Modbus Slave Parity Error

Hva betyr I x .Slave.ParityError ?

This boolean tag indicates that a parity error occurred during Modbus slave communication. A value of 1 (Occurrence) means a data transmission error was detected due to incorrect parity. This suggests corruption in the serial data stream received by the slave, leading to unreliable data processing.

• Incorrect parity setting on the Modbus master or Modbus slave module
• Noise or electromagnetic interference (EMI) on the communication line corrupting data bits
• Damaged or loose serial communication cable connections

1. 1

   Verify the parity setting in the Modbus slave module's configuration matches the Modbus master's setting.

2. 2

   Inspect the serial communication cable for physical damage or loose connections at both the module and master ends.

3. 3

   Check for sources of electromagnetic interference (EMI) near the communication line and implement shielding if necessary.
