FANUC Standard Interface Commands
This section describes standard interface commands used in TCP communications between a FANUC robot and Mech-Mind Vision System. The robot (the client) sends commands to Mech-Mind Vision System (the server), and Mech-Mind Vision System returns the processed data to the robot.
Before you call the commands, take note of the following items:
-
Unit of data:
-
The unit of joint positions is degree (°).
-
A robot’s flange pose or TCP consists of the position and pose. The position is represented in XYZ coordinates and is measured in millimeters (mm); the pose is represented in Euler angles and is measured in degrees (°).
-
-
Vision point and waypoint:
-
Vision point: An object recognized by Mech-Vision. A vision point has information including the object pose, label, dimensions, and custom data.
-
Waypoint: Each point that the robot reaches when moving along the planned path. A waypoint has information including the robot pose, label, and motion type. Waypoints can be divided into two categories:
-
Vision Move waypoint: Waypoint corresponding to the Vision Move Step.
-
Non-Vision Move waypoints, which refer to the waypoints corresponding to Move-type Steps other than the Vision Move Step.
-
-
Communication Initialization
Command Format
MM_INIT_SKT(C_Tag,Ip_Addr,Svr_Port,Time_Out)
Input Parameters
C_Tag
This parameter specifies the string-type robot port number. Valid values: 1 to 8.
Ip_Addr
This parameter specifies the string-type IP address of the IPC.
Svr_Port
This parameter specifies the port number used by the IPC to establish the communication between the IPC and the robot. This port number must be consistent with the host port number that is specified for robot communication in the toolbar of Mech-Vision.
Time_Out
This parameter specifies the communication timeout period. Unit: minutes.
Run Mech-Vision Project
Command
This command triggers the Mech-Vision project to run. When the Mech-Vision project is running, the vision system triggers the camera to capture images and then process the returned images with algorithms to produce a series of vision points or waypoints.
|
Calling Sequence
-
You should set Step parameters before starting a Mech-Vision project. Therefore, call Switch Mech-Vision Parameter Recipe or Input Object Dimensions to Mech-Vision Project before calling Run Mech-Vision Project.
-
Vision system gets vision points and waypoints only after a Mech-Vision project runs. Therefore, call Run Mech-Vision Project before calling Get Vision Result, Get Planned Path in Mech-Vision, or Get Mech-Vision Custom Data.
Command Format
MM_START_VIS(Job,Pos_Num_Need,SendPos_Type,Pr_Num)
Input Parameters
Job
Mech-Vision project ID. You can view the project ID of a Mech-Vision project in the Project List section of Mech-Vision. The project ID is the number before the project name.
Pos_Num_Need
This parameter specifies the expected number of vision points or waypoints to be obtained from the Mech-Vision project. Value range: 0 to the largest positive integer.
If the Mech-Vision project has a Path Planning Step, this parameter indicates the expected number of waypoints. Otherwise, it indicates the expected number of vision points. |
-
0: Obtain all vision points or waypoints from the Mech-Vision project.
-
A positive integer: Obtain the specific number of vision points or waypoints from the Mech-Vision project.
-
If the total amount of vision points or waypoints output by the Mech-Vision project is smaller than the parameter value, this command will obtain the number of all vision points or waypoints.
-
If the total amount of vision points or waypoints output by the Mech-Vision project is larger than or equal to the parameter value, this command will obtain the number of vision points or waypoints as specified by this parameter.
-
|
SendPos_Type
This parameter specifies the way in which the real robot pose is sent to the Mech-Vision project. Valid values: 0, 1, 2, and 3. The following table describes the details.
SendPos_Type | Description | Applicable scenario |
---|---|---|
0 |
The command does not send the robot pose data to the Mech-Vision project. |
This setting is recommended when the camera is mounted in the Eye To Hand method. If the Path Planning Step is used in the Mech-Vision project, the start point of the planned path will be the Home point set in the path planning tool. |
1 |
The robot joint positions and flange pose must be input to the Mech-Vision project. |
This setting is recommended when the camera is mounted in the Eye In Hand method. Applicable for most robot types except gantry robots. |
2 |
The robot flange pose must be input to the Mech-Vision project. |
This setting is recommended when the camera is mounted in the Eye In Hand method. The robot has the flange pose but no joint positions, such as a gantry robot. |
3 |
This command sends custom joint positions to the Mech-Vision project. |
This setting is recommended when the camera is mounted in the Eye To Hand method, and the Mech-Vision project contains the Path Planning Step, whose start point needs to be set at the robot side. |
Pr_Num
This parameter specifies the position register ID. The position register that corresponds to the ID stores custom joint position data.
-
If the SendPos_Typeparameter value is 3, the joint positions represented by the position register here will be sent to the Path Planning Step of the Mech-Vision project for planning as the first waypoint. In this case, the data type of the position register must be modified to the joint position type.
-
If SendPos_Type is set to a parameter value other than 3, the joint position data that is represented by the position register is of no practical use but the position register ID must be set.
Get Vision Result
Command
This command obtains vision result, namely, a series of vision points, from Mech-Vision. The object pose of the vision point (namely, the output of the poses port of the Output Step) will be automatically converted to the robot’s TCP by the vision system. The process is as follows.
-
Convert the object pose from a quaternion to Euler angles.
-
Rotate the object’s pose around the X-axis by 180° to orient its Z-axis downward.

Set Gripper DO List
Calling Sequence
This command should be called after Get Gripper DO List.
Run Mech-Viz Project
Command
This command triggers the Mech-Viz project to run. Mech-Viz plans the robot’s motion path based on the vision result output by Mech-Vision.
Right-click the project name in the project resource panel in Mech-Viz and select Autoload Project. |
Calling Sequence
You should set Step parameters before starting a Mech-Viz project. Therefore, call Read Mech-Viz Step Parameter or Set Mech-Viz Step Parameter before calling Run Mech-Viz Project.
Command Format
MM_START_VIZ(SendPos_Type,Pr_Num)
Input Parameters
SendPos_Type
This parameter specifies the way in which the real robot pose is sent to the Mech-Viz project. Valid values: 0, 1, and 2. The following table describes the details.
Robot pose type | Description | Applicable scenario |
---|---|---|
0 |
The command does not need to send the robot pose to the Mech-Viz project. The simulated robot in Mech-Viz moves from the initial pose (joint positions = [0, 0, 0, 0, 0, 0]) to the first waypoint. |
This setting is recommended when the camera is mounted in the Eye To Hand method. |
1 |
In this command, the robot sends its current joint positions and flange pose to the Mech-Viz project. The simulated robot in Mech-Viz moves from the input joint positions to the first waypoint. |
This setting is recommended when the camera is mounted in the Eye In Hand method. |
2 |
In this command, the robot sends the joint positions of a teach point (the custom joint positions), instead of the current joint positions, to the Mech-Viz project. The Mech-Viz project uses the joint positions to plan the next path in advance while the robot is not in the camera capture region, as shown below. The simulated robot in Mech-Viz moves from the input joint positions to the first waypoint. |
This setting is recommended when the camera is mounted in the Eye To Hand method. |
Why robot pose type 2 is recommended when the camera is mounted in the Eye To Hand method?
In the Eye To Hand method, the camera can perform image capturing for the next round of path planning before the robot returns to the image capture region and picking region, thus shortening the cycle time. The image below demonstrates how a robot works in the placing region.
If SendPos_Type is set to 1, the robot will send the current pose to Mech-Viz. It is possible that the real robot moves to other positions before reaching the first waypoint. However, the simulated robot moves directly to the first waypoint of the Mech-Viz project from the pose sent by the robot. Consequently, there may be a mismatch between the paths of the real robot and simulated robot. This mismatch can potentially lead to unpredicted safety hazards, especially if collision is detected in the path of the simulated robot.
On the other hand, if SendPos_Type is set to 2, the robot will send the image-capturing pose set by teach to Mech-Viz. Thus, the real robot can trigger the next round of path planning in Mech-Viz when the real robot is in the image-capturing region and the cycle time can be shortened.
In conclusion, robot pose type should be set to 2 for projects in the Eye To Hand method.
Pr_Num
This parameter specifies the position register ID. The position register that corresponds to the ID stores custom joint position data.
-
If the SendPos_Typeparameter value is 2, the joint positions represented by the position register here will be sent to the Mech-Viz project for planning as the first waypoint. In this case, the data type of the position register must be modified to the joint position type.
-
If SendPos_Type is set to a parameter value other than 2, the joint position data that is represented by the position register is of no practical use but the position register ID must be set.
Set Exit Port for Branch by Msg Step in Mech-Viz
Command
This command sets the exit port for the Branch by Msg Step. When the next Step is a Branch by Msg Step, the Mech-Viz project will wait for this command to specify the exit port.
Calling Sequence

Command Format
MM_SET_BCH(Branch_Num,Export_Num)
Input Parameters
Branch_Num
This parameter specifies the Step ID of the Branch by Msg Step. The value is a positive integer. The Step ID is displayed in the Step parameter panel. For example, the Step ID of the Step in the image above is 1.
Export_Num
This parameter specifies the exit port ID of the Branch by Msg Step. The value is a positive integer. When the parameter value is set to N, the Mech-Viz project exits from the port with an ID of N-1 of the Branch by Msg Step.
Set Current Index in Mech-Viz
Command
This command sets the value of the Current Index parameter of index-type Steps. Steps that include the Index section include Move by Grid, Move by List, Custom Pallet Pattern, and Predefined Pallet Pattern.
Calling Sequence
Index-type Steps are often preceded by a Branch by Msg Step. The robot should call commands in this order: Run Mech-Viz Project, Set Current Index in Mech-Viz, and Set Exit Port for Branch by Msg Step in Mech-Viz. This is to ensure that Mech-Viz has enough time to set the Current Index value.
Command Format
MM_SET_IDX(Skill_Num,Index_Num)
Input Parameters
Skill_Num
This parameter specifies the Step ID of the Index-type Step. The value is a positive integer. The Step ID is displayed in the Step parameter panel. For example, the Step ID of the Step in the image above is 3.
Index_Num
This parameter specifies the current index for a Index-type Step. The value is a positive integer. When this parameter value is set to N, the current index of the corresponding Step is N-1.
Get Planned Path in Mech-Viz

By default, the vision system sends no more than 20 waypoints at a time. Therefore, the maximum default value of this parameter is 20. To modify the default maximum number of poses to obtain each time as needed, go to Robot and Communication >
in the toolbar of Mech-Vision. The upper limit is 30.Reg_VPos_Num
This parameter specifies the ID of the numeric register. The numeric resister corresponding to the ID stores the position ID of the Vision Move waypoint that corresponds to the Vision Move step in the Mech-Viz project in the path. If the waypoint does not exist in the path, the petameter value is 0.
If the planned path consists of the following waypoints in sequence: Fixed-Point Move_1, Fixed-Point Move_2, Vision Move, and Fixed-Point Move_3, the position ID of the Vision Move waypoint is 3.
Reg_Status
This parameter specifies the ID of the numeric register. The numeric register that corresponds to the ID stores the status code of this command. If the command is successfully executed, the status code is 2100. If a command fails to be run, a specific error code is returned. For details, see Status Codes and Troubleshooting.
By default, after the robot sends this command, the vision system returns the result in 10 seconds. If the vision system fails to return any result in 10 seconds, a timeout error code is returned. To modify the default timeout period as needed, go to Robot and Communication > in the toolbar of Mech-Vision. |
