This module implements FANUC’s Focas protocol connectivity allowing the user to collect different data from a FANUC CNC machine.
This protocol implementation allows the communication to such devices and provides the user the ability to create endpoints for reading and subscribing for changes on the data provided by them.
Below you can see configuration parameters and examples on how to build a commissioning file for this protocol.
Available Focas methods. For full details of each method please consult the Focas documentation.
All endpoints utilizing these methods have to be defined as endpoints with the subscribe operation. The output will be provided as JSON object.
cnc_exeprgname
Reads the full path name of the program which is currently being executed in CNC.
Example output:
cnc_rdgcode
Reads the information of CNC about the commanded G code.
Required properties:
type
block
numGcd
Example output:
cnc_rdopnlsgnl
Reads the output signal image of software operator’s panel.
Required properties:
slctData
Example output:
cnc_rdprgnum
Reads the program number (modal O number) of the program which is currently selected in CNC.
Example output:
cnc_rdspeed
Reads the actual feed rate and the actual rotational speed of the main spindle.
Required properties:
dataType
Example output:
cnc_rdspload
Reads the load information of the serial spindle.
Required properties:
spindleNumber
Example output:
cnc_statinfo2
Reads the status information of CNC.
Example output:
cnc_sysinfo
Reads system information such as kind of CNC system, Machining(M) or Turning(T), series and version of CNC system software and number of the controlled axes.
Example output:
pmc_rdpmcrng
Reads the PMC data of the specified PMC address/range.
Required properties:
addressType
dataType
addressStart
addressEnd
dataLength
Example output:
All endpoints utilizing these methods have to be defined as endpoints with the read operation since they require input provided on the request-topic (req). The output will be provided as JSON object.
For read endpoints, additionally a correlation ID (id) can be set in the payload of the request message, to ensure the correct identification of responses to specific requests.
program_download
The program code string has to be formatted in a certain way to be processable by the method. To convert the program to this format the following steps have to be applied to the program code:
Insert a leading line break ; all data before that will be ignored
Replace all line breaks with
Remove all space characters
Remove all semicolons
The example code:
would be converted to the string:
The program will be downloaded to the directory which is set as “Background Folder” in the Fanuc controller.
Example output:
Download the specified NC data to the controller. For this method, you will need to specify a valid G-code program (see e.g. ) in the message payload as string value of the value key and publish it on the endpoint’s request topic (req).
