FS-8700-123 MetOne Particle Counter Serial Driver Manual 4.4. Page 9 of 26 Client Side Map Descriptors 4.4.1.
Map Descriptor Example 1 – Read Hold ( or Sample) Times from a Device. Page 10 of 26 While not mandatory, giving each Map Descriptor a unique name will help to diagnose configuration problems. Function, RDBC, Length, 3, Scan_Interval 5.0s This task must be executed every 5 seconds. Reserves 3 Data array locations for storing data. Met1_Function, Hold Time , Tells the driver to read the Hold Time from the field device. Node_Name MET1, The name of the Node.
Map Descriptor Example 2 – Write Hold (or Sample) Times to a Device. Page 11 of 26 Map Descriptor Example 3 – Read the operating mode. Met1_Function, Hold Time , Change this to ‘Sample Time’ to command a sample time or make two Map Descriptors – each with the correct time function. Node_Name MET1, Tells the FieldServer that one element of the data array is reserved for this Map Descriptor.
Map Descriptor Example 4 – Start / Stop Counting. Page 12 of 26 Function, wrbx, Command is sent each time the value at DA:offset is updated. Data_Array_Offset, 0, Met1_Function, Count , Set length to 1 for this Met1_Function Node_Name MET1, Scan_Interval 1.0s When the function is wrbx then the scan interval parameter is ignored. Length, 1, FieldServer Technologies 1991 Tarob Court Milpitas, California 95035 USA Web:www.fieldServer.
Map Descriptor Example 5 – Change Mode Page 13 of 26 Data_Array_Offset, 0, Function, wrbx, Met1_Function, Mode , Set length to 1 for this Met1_Function Node_Name MET1, FieldServer Technologies 1991 Tarob Court Milpitas, California 95035 USA Web:www.fieldServer.com Tel: 408 262-2299 Fax: 408-262-2269 Toll_Free: 888-509-1970 email: support@fieldServer.
Map Descriptor Example 6 – Select Device Page 14 of 26 Function, wrbx, Node_Name MET1, The Node_Name connects this Map Descriptor to the Node Descriptor and that is where the driver finds the Node_ID parameter. Data_Array_Offset, 0, Length, 1, Set length to 1 for this Met1_Function Met1_Function, Device Select, FieldServer Technologies 1991 Tarob Court Milpitas, California 95035 USA Web:www.fieldServer.com Tel: 408 262-2299 Fax: 408-262-2269 Toll_Free: 888-509-1970 email: support@fieldServer.
Map Descriptor Example 7 – Read the Current Record Page 15 of 26 Data_Array_Offset, 0, Function, Rdbc, Node_Name MET1, Length, 20, Scan_Interval 1.0s The length must be set to a value large enough to store the 8 fixed data items and the variable number of count fields. Met1_Function, Current Record, FieldServer Technologies 1991 Tarob Court Milpitas, California 95035 USA Web:www.fieldServer.com Tel: 408 262-2299 Fax: 408-262-2269 Toll_Free: 888-509-1970 email: support@fieldServer.
Map Descriptor Example 8 – Dumping the Current Record Page 16 of 26 Data_Array_Offset, 0, DA_Byte_Name, DA_DUMP, Function, Rdbc, A secondary Data Array is specified with the ‘DA_Byte_Name’ parameter. When this is done the driver stores the read current record response, byte for byte, in the secondary DA. Data_Array_Name, DA_DATA, Met1_Function, Current Record, Length, 20, The length specified the amount of Data Array space reserved for primary storage and has no effect on the dump.
Map Descriptor Example 9 – An alternate way of storing the current record. Page 17 of 26 FieldServer Technologies 1991 Tarob Court Milpitas, California 95035 USA Web:www.fieldServer.com Tel: 408 262-2299 Fax: 408-262-2269 Toll_Free: 888-509-1970 email: support@fieldServer.
Map Descriptor Example 10 – Reading from a SubDevice/Port Page 18 of 26 Map_Descriptors Map_Descriptor_Name, Read Record, Data_Array_Offset, 0, Function, Rdbc, will select Address, 3, ‘SubDevice’ Met1_SubDev_or_Port, SubDevice, Number SubDevices 1..64 Number Ports 0..63 Use the keyword ‘Port’ to select a specific port. Then driver number 3. Node_Name MET1, Length, 20, Scan_Interval 1.0s Then driver will read the current record.
Map Descriptor Example 11 – Selecting a Sub-Device/Port Page 19 of 26 DA_MODE_CTRL, Select Device, 0, rdbc, Function, MET1, Node_Name Port, Met1_SubDev_or_Port, When using this type of Map Descriptor, the driver does not send a device select message first. Driver will send a port select message to the port specified with the address parameter.

FS-8700-123_MetOne Particle Counter by Hach Ultra Analytics Manual Page 23 of 26 Message MET1:#13 Err. Node=%d cant be selected because not defined in config. Description The reported device could not be selected because there isnt a node descriptor whose Node_ID matches the reported device.4 The driver has set the default poll delay to the reported "Met1:#14 FYI Poll_Delay value. This setting can be overridden in the configuration overridden to %d file.
FS-8700-123_MetOne Particle Counter by Hach Ultra Analytics Manual Page 24 of 26 Appendix A.2. Driver Exposed Operating and Error Statistics In addition to the normal operating stats the driver can expose additional operating/error stats in a Data Array which can be monitored by a remote device. A special Data Array name is required. The driver recognizes the Data Array by its name which must be "met1-stats" The following example shows how this Data Array can be configured.
