About This Page

Use this page to modify an existing configured device.

You can Name the device and set its Modbus Address. Leave the Modbus IP Address at 0.0.0.0 to disable Modbus/TCP for this device. A non-zero value enables Modbus/TCP.

Automatic Device Instances: When using up to 10 BASgatewayLX units, assign a different Region Number (0-9) for each BASgatewayLX to make auto-created Device Instances unique across multiple EIA-485 networks. Uncheck Device Instance Auto to manually enter a Device Instance. Otherwise, it is an automatically created 7-digit value as follows. The first 3 digits are 245 (Contemporary Controls' Vendor ID). The next digit is your specified Region Number. The last 3 digits are the Modbus Address you entered above. Max Consecutive Read: Set the number of registers (1-125) to be read as a group. Default = 1. Write Code: Use function code 6 (Preset Single Register)or 16 (Preset Multiple Registers) to write one holding register. Default = 6. Max Consecutive Errors: Set the number of consecutive communication errors (1-300) after which to report a device offline. Default = 1. NOTE: if your Modbus/TCP devices use duplicate Modbus addresses then disable Device Instance Auto and manually assign a Device Instance.
