The SDL File

The SDL file contains definitions that all SECS messages for that equipment connection are validated against. Any messages that fail to validate against the SDL file will be inserted into the Errors table for the equipment connection instead. The SDL file uses JSON syntax to define datatypes, SECS Items, and SECS Messages.

Each equipment connection can accept one SDL file. However, if no file is specified, the default 'messages.sdl' file will be used. The SECS message definitions in the default SDL file are based on the definitions in the SECS-II standard (SEMI E5-0712) and the GEM standard (SEMI E30-0307).

The SDL files can be edited in the Gateway Webpage using the built in SDL editor, or they can be downloaded from the Equipment Connections page so that they can be edited in a text editor and re-uploaded at a later time.

SDL File Format

The SDL file should be formatted using JSON syntax. It follows a simple structure, which is demonstrated in the example below. There are four main parts to the SDL file:

doc

The doc comes first and provides any overall documentation for the file. We recommend good documentation so that it is easy to make changes if needed.

formats

The formats list out all of the datatype formats that the items will use. It does not need to include datatypes that are not used by the items.

items

The items are used by the messages to relay information to and from the equipment. The items are sorted alphabetically, with each item under its corresponding letter. Each letter can have any number of items under it.

messages

The messages handle communication with the equipment. Each message is sorted by stream, with each function listed in order under its corresponding stream. There can be multiple streams under messages, and multiple functions under each stream.

   }
}


SECS Datatype Formats

The formats section should list all datatypes that will be used in the items section. The formats section can be as long as it needs to be, and can even consolidate multiple values into a single value for ease of use. Notice in the example below, the different size integer and floats can all get consolidated into an 'I' and an 'F ', which makes it easier to use when specifying all of those datatypes in the Item Definition.


 SDL Formats Definition Example

{  
   "A":{  
      "doc":"ASCII"

         "F8"
      ]
   }
}


SDL Item Definitions

The SDL Item Definitions list out all possible items that are used in SECS Message definitions. If a SECS Message attempts to use an item that isn't defined in the SDL file, it will throw an error.


 SDL Item Definition Example
SDL Item Definition Example
{  
   "A":{  
      "ACKC7":{  
         "doc":[  
            "ACKC7, Acknowledge Code"
         ],
         "formats":[  
            "B"
         ],
         "bytes":1,
         "codes":{  
            "0":"Accepted",
            "1":"Permission not granted",
            "2":"Length error",
            "3":"Matrix overflow",
            "4":"PPID not found",
            "5":"Mode unsupported",
            "6":"Command will be performed with completion signaled later",
            ">":[  
               6,
               "Other error"
            ]
         }
      }
   }
}



Each item has a list of properties that define what the item is.

Property NameDescriptionExample Formatting
docProvides information about what the item is along with any other useful information.
{  
   "doc":[  
      "TIME, Time of day",
      "12, 16 bytes, or Extended format as specified by the TimeFormat equipment constant value setting.",
      "12-byte format YYMMDDhhmmss",
      "16-byte format YYYYMMDDhhmmsscc",
      "Extended (max 32 byte) format YYYY-MM-DDThh:mm:ss.sTZD (see SEMI E148)"
   ]
}
formats

A list of the possible datatypes that the item can be.

Can also be a list of items, as in the second example.
The type can be a list of CATTRDATA objects, or any of the other listed objects.

      "A",
      "F",
      "U",
      "I"
   ]
}
bytes

How many bytes the item must have. If bytes is > 1, then the item is an array of bytes.
Only applies to single byte datatypes such as Binary, Boolean, U1 and I1.

{
	"bytes":1
}
codes

Lists possible values an item can have and what each means.
A value of ">" means any value greater than the largest code value.

{  
   "0":"Accepted",

   "2":"Length error",
   "3":"Matrix overflow",
   "4":"PPID not found",
   "5":"Mode unsupported",
   "6":"Command will be performed with completion signaled later",
   ">":[  
      6,
      "Other error"
   ]
}

}
pattern

A java regular expression that the ASCII value must match.
Only applies to ASCII datatypes.

{  
   "pattern":"^[0-9]{6}|[0-9]{8}$"
}


SDL Message Definitions

The message definitions list out all possible SECS messages that will be used when communicating with the equipment. There can be many streams listed, each with multiple functions.


 SDL Message Definitions Example
SDL Message Definition Example
{  
   "S6F1":{  
      "doc":[  
         "Trace Data Send",
         "This function sends samples to the host according to the trace setup done by S2,F23."
      ],
      "block":"multiple",
      "direction":"h<-e",
      "or":[  
         {  
            "reply":true
         },
         {  
            "reply":false
         }
      ],
      "CommonID":[  
         "TRID"
      ],
      "realtime":true,
      "SQLTags":true,

            "function":2,
            "reply":false
         },
         "body":{  
            "format":"B",
            "value":0
         }
      },
      "body":[  
         "TRID",
         "SMPLN",
         "STIME",
         [  
            "SV",
            "..."
         ]
      ]
   }
}


Property NameDescriptionExample
docProvides information about what the message is along with any other useful information.
{  
   "doc":[  
      "Are You There Request",
      "Establishes if the equipment is on-line."
   ]
}
block

The size in bytes of the entire SECS message. There are two possible values:

  • "single" - The message will not be larger than 254 bytes.
  • "multiple" - The message will be larger than 254 bytes.

This property is only important for maintaining compatibility with the SECS-I protocol through Serial connection.

{  
   "block":"single"
}

direction

Determines whether the message should come from the equipment, the host, or either. Possible values are:

  • "h->e"- The message goes from the host to the equipment.
  • "h<-e" - The message goes from the equipment to the host.
  • "h<->e" - The message goes either direction.
{  
   "direction":"h<->e"
}
replyTrue if the message expects a reply, false if not.
{  
   "reply":true
}
autoReply

An auto response with a given message when a given message is received.

If included in a message, the example will auto reply with a S1F2 message.

{  
   "autoReply":{  
      "header":{  
         "stream":1,
         "function":2,
         "reply":false
      },
      "body":[  

      ]
   }
}
body

A list of items that the stream will implement.

The body list can contain lists of items, or the special "...", which signifies a variable list.

In the second example, depending on the value of HCACK, any amount of a list of CNAME and CPACK can be returned.

{  
   "body":[  
      "DATAID",
      "DATALENGTH"
   ]
}
{  
   "body":[  
      "HCACK",
      [  
         [  
            "CNAME",
            "CPACK"
         ],
         "..."
      ]
   ]
}
orWill list multiple possibilities. Can also exist within a body definition.
{  
   "or":[  
      {  
         "direction":"h->e",
         "body":[  

         ]
      },
      {  
         "direction":"h<-e",
         "body":[  
            "MDLN",
            "SOFTREV"
         ]
      }
   ]
}
CommonID

Used to identify certain messages, especially when used to group multiple incoming messages together.

In the example, a trace will have multiple S6F1 messages as the status variable is traced over time.
The CommonID will use the trace ID to link all messages from the same trace together, allowing for easy retrieval from the database.


{  
   "S6F1":{  
      "doc":[  
         "Trace Data Send",
         "This function sends samples to the host according to the trace setup done by S2,F23."
      ],
      "block":"multiple",
      "direction":"h<-e",
      "CommonID":[  
         "TRID"
      ],
      "realtime":true,
      "SQLTags":true,
      "autoReply":{  
         "header":{  
            "stream":6,
            "function":2,
            "reply":false
         }
      }
   }
}
realtime

If true, will be processed by a Message Handler script. The message handler must be named onSecsGemRealtimeUpdate.
Will use the CommonID for updates. See SECS/GEM Messages for more information on the Message Handler.

{  
   "realtime":true
}
SQLTags

If true, will create Tags in the SECSGEM provider automatically, using the CommonID as a folder name. Will create Tags in the location as follows:

SECSGEM->EquipmentName→Stream and Function->CommonID→message value tags

Can also be overridden to use a folder name other than the CommonID, like in the second example.

{  
   "SQLTags":true
}
{  
   "SQLTags":[  
      "SMPLN"
   ]
}

SDL Message Defaults

The messages section typically starts with a default set of properties before the list of SECS messages. These default property values will be used in the message when the property is not present in the message definition.

SDL Message Defaults
{  
   "defaults":{  
      "doc":[  
         "Default values for properties that are missing."
      ],
      "block":"single",
      "reply":false,
      "direction":"h<->e",
      "body":null
   }
}


SDL File Editor

In the Equipment Connections section,  you can make edits to the equipment's SDL file right in the Gateway Webpage by clicking the More button and selecting the 'edit sdl file' option.

After editing the SDL File, the equipment connection must be restarted for the changes to take effect.

Once in the SDL file editor, there are a few things that can be done. The six dots to the left of each row circled in blue above, allow you to change the order of the rows by clicking and dragging a row and dropping it in a new spot.

The buttons near the top circled in green apply to the document as a whole:

ButtonDescription

Expands all nodes.

Collapses all nodes.

Undo the last edit made to the file.

Redo the last Undo.


Finally, the buttons circled in redbring up a context menu with a few options that allow you to add and remove rows and change the row type:

OptionDescription
Type

Change the type of the row. Possible options are:

  • Auto - Automatically determines the type based on the value.
  • Array - Contains an ordered collection of values.
  • Object - Contains an unordered set of key/value pairs.
  • String - Determined from the value, but always returned as a string.
SortSorts the rows in either ascending or descending order.
  • Ascending - Sort the children of this array in ascending order.
  • Descending - Sort the children of this array in descending order.
Insert

Inserts a new row before the selected row. Possible types are:

  • Auto - Automatically determines the type based on the value.
  • Array - Contains an ordered collection of values.
  • Object - Contains an unordered set of key/value pairs.
  • String - Determined from the value, but always returned as a string.
DuplicateDuplicates the row, including all sub elements
RemoveRemoves the row and all sub elements.


Each row can be drilled into by clicking on the expand arrow to the left of the element, which allows you to see the sub elements. Many times, these sub elements can also be drilled into to find more sub elements. Once you find the element you want to modify, you can simply edit the text to make a change.


Once all the edits are made, clicking the 'Save SDL File' button at the top right of the screen will save your changes. However, the changes won't take effect until the equipment connection is restarted.

Restart the Equipment

To restart the equipment, simply click the More button next to the Equipment on the Equipment Connections page, and select the 'restart' option.


Default SDL File

The default 'message.sdl' file is used when no other SDL file is specified.
