6.3.4 Slave_Id
The following Map Descriptor is used to respond to the Report Slave_Id request. The FieldServer's Slave_Id is 11 and the run status depends upon the data
validity at the specified offset in the specified Data Array - if the data is valid, the status will be 255 (running) otherwise the status will be 0 (off).
