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.
