Common Troubleshooting

Issue: Timer Not Updating with Modbus Word

Symptoms:

The timer does not update its start value when a new word is received via Modbus. The timer remains at its initial value regardless of the input.

Solution:

Ensure that the Modbus communication settings are correctly configured in both the Zelio SR3B101BD and the Modbus master device. Verify that the Modbus address and data type match between the devices. Additionally, check that the timer’s configuration in the Zelio software is set to accept the external delivery input.

Issue: Incorrect Data Type for Modbus Word

Symptoms:

The timer receives a value but does not interpret it correctly, leading to unexpected behavior or incorrect timing.

Solution:

Confirm that the data type of the Modbus word matches the expected input format for the timer. For instance, if the timer expects an integer value, ensure that the Modbus word is being sent as an integer. Adjust the data type in the Modbus master device if necessary.

Issue: Modbus Communication Failure

Symptoms:

The Zelio SR3B101BD does not receive any data from the Modbus master device, resulting in the timer not being updated.

Solution:

Check the physical connections and cabling between the Modbus master device and the Zelio SR3B101BD.
