SINUMERIK Data Access

This chapter outlines all possible native addresses to access memory and data. These addresses must be configured within the device configuration.

Format

In general, the address following format:

Classical SINUMERIK path from HMI operate. Example:

/Channel/MachineAxis/measPos1[u1, 1]

Or SIEMENS and IEC syntax. Example:

DB10.DBD 20

Global Addresses

Following data points are provided by the plugin. The Global path is used:

Address	Description	Data Type
/Global/Available	Returns the available flag. true = machine is online	System.Boolean
/Global/SignOfLife	Sign of life. Toggles in 1Hz if machine is online	System.Boolean

NC Variables

The following list is an extract from the HMI Operate. Check the Siemens Documentation for other data addresses.

Machine Status

Address	Description	Data Type
/Channel/State/chanAlarm[u1]	Returns the alarm status of the machine	System.Boolean
/Bag/State/opMode[u1]	Returns the operation mode: 0: JOG mode 1: MDA mode 2: AUTO mode	System.Int32
/Channel/State/acProg[u1,1]	Program running state 0: reset 1: stopped 2: running 3: waiting 4: interrupted	System.Int32
/Channel/State/totalParts[u1]	Part counter	System.Int32

Program Information

Address	Description	Data Type
/Channel/ProgramPointer/progNameVL[u1,1]	Main NC program	System.String
/Channel/ProgramInfo/actPartProgram[u1,1]	Program header of the main program	System.String
/Channel/ProgramInfo/progName[u1]	Current NC program	System.String
/Channel/ProgramInfo/actBlockA[u1,1]	Current NC Block	System.String
/Channel/ProgramInfo/blockNoStr[u1]	Current sequence number	System.String
/Channel/State/actTNumberLong[u1,1]	Current Tool number	System.Int32

Feed and Feedrates

Address	Description	Data Type
/Channel/State/feedRateIpoOvr	Feedrate Override	System.Double
/Channel/State/actfeedrateipo[u1]	Current feed	System.Double
/Channel/State/cmdFeedRateIpo[u1]	Programmed feed	System.Double

Spindle

Address	Description	Data Type
/Nck/Spindle/speedOvr[1]	Spindle Speed Override	System.Double
/Channel/spindle/actspeed[u1,1]	Current spindle speed	System.Double
/Channel/Spindle/cmdSpeed[u1,1]	Programmed spindle speed	System.Double

Timers

Address	Description	Data Type
/Channel/ChannelDiagnose/cuttingTime[u1, 1]	Cutting timer in seconds	System.Double
/Channel/ChannelDiagnose/operatingTime[u1, 1]	Operation timer in seconds	System.Double
/Nck/State/sysTimeSinceStartup[1]	Power on timer in seconds	System.Double

Example

Example of a DataNode configuration:

{
  "Id": "F7F0FBE1-388C-4B87-94AF-95869AABCE6D",
  "Name": "Value",
  "DataClass": "Event",
  "DataType": "System.Double",
  "Address": "/Channel/MachineAxis/measPos1[u1, 1]",
  "Access": {
    "Read": true,
    "Receive": true
  }
}

Machine Data

Machine data of the control is accessed via an address that comprises a prefix and the name of the machine data. The prefix is specific for the particular machine data type.

Machine Data Type	Prefix
General machine data	/NC/_N_NC_TEA_ACX
Channel machine data	/NC/_N_CH_TEA_ACX
Axis machine data	/NC/_N_AX_TEA_ACX
General setting machine data	/NC/_N_NC_SEA_ACX
Channel setting machine data	/NC/_N_CH_SEA_ACX
Axis setting machine data	/NC/_N_AX_SEA_ACX

NOTE

When accessing channel-specific machine data, the address must be extended by the channel number [<ChannelNr>]. For indexed machine data, a second index must also be used [<ChannelNr>,<Index>].

NOTE

When accessing axis machine data, the address must be extended by the axis number [<AxisNr>]. For indexed machine data, a second index must also be used [<AxisNr>,<Index>].

Example of an indexed general machine data $VALUE[2]:

{
  "Id": "F7F0FBE1-388C-4B87-94AF-95869AABCE6D",
  "Name": "Value",
  "DataClass": "Event",
  "DataType": "System.Double",
  "Address": "/NC/_N_NC_TEA_ACX/$VALUE[2]",
  "Access": {
    "Read": true,
    "Receive": true
  }
}

Global User Data (GUD)

The SINUMERIK control system allows global variables to be defined which can then be read and written to in an NC program. The GUD variables can be defined NC-globally or channel-specifically.

DEF

GUDs are defined in DEF files in SINUMERIK controls

File Name	Description
MGUD.DEF	Definitions for global machine manufacturer data
UGUD.DEF	Definitions for global user data
GUD4.DEF	User-definable data
GUD8.DEF, GUD9.DEF	User-definable data

The DEF files are automatically downloaded by the Sinumerik plugin from directory /_N_DEF_DIR.

To access variables declared in one of those files, create a data node and use the following format to address the GUD variable: <GudFileName>/<VariableName>, e.g. GUD8/MY_VARIABLE[u1]

CAUTION

Downloading the DEF file manually and the creation of a device property (e.g. DEF:GUD8) is NOT SUPPORTED anymore in the current version.

Example of an indexed channel GUD data:

NOTE

Since TOOL_LIFE_CUR_ is a channel based array, it also requires to declare from which channel the data must be read/written, e.g: channel 1 as TOOL_LIFE_CUR_[u1,2].

{
  "Id": "F7F0FBE1-388C-4B87-94AF-95869AABCE6D",
  "Name": "Value",
  "DataClass": "Event",
  "DataType": "System.Double",
  "Address": "GUD8/TOOL_LIFE_CUR_[u1,2]",
  "Access": {
    "Read": true,
    "Receive": true
  }
}
