| To allow support for datatypes larger than 16 bit, has been designed an extension to the protocol to treat long 32 bit dimension values. Implementing this feature preserves the formatting of the message standard modbus it uses the contents of two consecutive addresses to represent a 32 bit value. When this extension is enabled (wider = 1), depending on the address used the slave responds with a 16-bit or 32-bit value for each log request. If the address is greater than 5000 will be returned a 32-bit value, if under the Protocol remains unchanged with response to 16 bits. | To allow support for datatypes larger than 16 bit, has been designed an extension to the protocol to treat long 32 bit dimension values.
