Convert BASgatewayLX CSV Configuration To BACRouter JSON

BASgatewayLX (Hereinafter referred to as LX) supports CSV configuration file. There are decent documents about the format and dozens of configuration samples for vary devices on their website. The convert tool we provided could convert the CSV file to JSON file which could be imported in BACRounter’s WebUI to create a Modbus slave station.

Matters need attention:

Though LX claims the object name should be unique, but the accessory “Profile Checker” does not check duplicated object name. We found a lots duplicated object names in the samples. So we decided to disable object with duplicated name in converting.

Some CSV files have characters out of UTF8 code page, we guess they are ISO-8859-1 encoding. So if we fail to decode CSV by UTF8, we fall back to ISO-8859-1.

LX supports maximum 64 bytes of object name and description (With ISO-8859-1 encoding?). BACRouter supports 64 bytes too, but with UTF8 encoding. There has possibility that 64 bytes in ISO-8859-1 is larger than 64 bytes when encoding as UTF8. We will tail-cut too long name and description and promote to user.

BACRouter doesn’t allow 2 output objects mapped to overlapped Modbus address, but LX seems to allow it. We will disable the conflicted object in converting.

LX defines register order for every 32 bits data, but BACRouter has to set unitary byte order for all objects. If the consistent byte order definitions are found when converting, the previous definition will be accepted, the conflict will be promoted to user.

BACRouter has object instance range of 0~999 for every slave, but LX seems no limitation. If instance larger than 999 is found, the object will be auto assigned a new instance.
