  • Determine whether the definition of the reference frame used by the robot model involves robot base height, and add a vertical offset accordingly.

Start Mech-Viz Project

In scenarios where both Mech-Vision and Mech-Viz are used, this function starts the Mech-Viz project that triggers the corresponding Mech-Vision project, and therefore the Mech-Viz project can plan the robot path based on the vision points received from Mech-Vision.

Unnamed image

Parameters

Input Parameters

  • Robot_Pose_Type: The type of robot pose to input to Mech-Viz. The value range is from 0 to 2.

  • Robot_Pose_JPS: Current joint positions of the robot. The data type is one-dimensional Array[0..5] of DInt.

The following table explains the relationship between Robot_Pose_Type and Robot_Pose_JPS/Robot_Pose_TCP.

Robot_Pose_Type Robot_Pose_JPS Robot_Pose_TCP Description Applicable Scenarios

0

0, 0, 0, 0, 0, 0

0, 0, 0, 0, 0, 0

No need to input the robot pose to Mech-Viz. The simulated robot in Mech-Viz moves from the initial pose JPs = [0, 0, 0, 0, 0, 0] to the first waypoint.

Project is in the eye-to-hand mode. This setting is not recommended.

1

Current joint positions of the robot

Current flange pose of the robot

Robot joint positions and flange pose must be input to Mech-Viz. The simulated robot in Mech-Viz moves from the input JPs to the first waypoint.

This setting is recommended for projects in the eye-in-hand mode.

2

Specific joint positions of the robot

0, 0, 0, 0, 0, 0

The robot joint positions of a point determined by teaching must be input to Mech-Viz. The input joint positions are used to trigger Mech-Viz 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 for projects in the Eye-To-Hand mode.

The reason for setting Robot_Pose_Type to 2 when the project is in the Eye-To-Hand mode: In the Eye-To-Hand mode, the camera can perform image capturing for the next round of path planning before the robot returns to the camera capture region and picking region, shortening the cycle time. If Robot_Pose_Type is set to 1, the robot’s current pose is sent to Mech-Viz. The simulated robot will move from the input pose to the first waypoint in the planned path, while the real robot might move to another point first, and then move to the first waypoint. Therefore, the path of the real robot may contain unpredicted collisions, leading to safety hazards. In conclusion, robot pose type should be set to 2 for projects in the eye-to-hand mode.

  • Command_Trigger_ACK: Used to determine whether the Command_Trigger signal is triggered successfully. 1 indicates that the signal is triggered successfully, while 0 indicates that the Command_Trigger signal has not been received.

Example

When Camera_User.Start_Viz is at the rising edge, this example runs the corresponding Mech-Viz project, and sets the initial joint positions of the simulated robot to the current joint positions of the real robot.

Get Message from Notify Step

After the Mech-Vision or Mech-Viz project is triggered, this function can be called to get message from the “Notify” Step.

When the “Notify” Step is executed in the Mech-Vision or Mech-Viz project, the message remains in the buffer of the vision system for only 1 second. Therefore, users should consider the timing of calling this function to ensure successful message retrieval. Additionally, after the PLC receives the message, the program should trigger the variable ToCamera.CLEAR_NOTIFY to clear the register data.

Parameters

Input Parameters

  • Get_Notify: Get a message from the “Notify” Step, triggered at a rising edge.

  • Command_Trigger_ACK: Used to determine whether the vision system is triggered successfully by the Command_Trigger signal. 1 indicates that the vision system is triggered successfully, while 0 indicates that the Command_Trigger signal has not been received.

Output Parameters

  • Command: The code whose value is assigned by the FB automatically.

abcmd31

Example Description

In this example, when Camera_User.Step_Num is set to 7 in the automatic mode, the value of FromCamera.NOTIFY_MSG is not 777. After the MM_Get_Custom_Notify function is enabled, when the Camera_User.Get_Notify variable is at the rising edge, the program retrieves the message from the “Notify” Step. If the message retrieval was successful, the value of FromCamera.NOTIFY_MSG changes to 777. Otherwise, if the value remains unchanged, the PLC will prompt an error after 3 seconds.
