Robotiq Hand-E Gripper - Instruction Manual
4.7.5. Master read & write multiple registers FC23
Function code 23 (FC23) is used for reading the status of the Gripper (robot input) and activating functionalities of the Gripper (robot
output) simultaneously. Examples of such data are Gripper status, object status, finger position, etc. Action requests are speed, force,
etc.
Example of reading and writing multiple registers FC23:
This message reads registers 0x07D0 (2000) and 0x07D1 (2001), which contains Gripper Status, Object Detection, Fault Status and
Position Request Echo. It also sets the position request, speed and force of the Gripper by writing to registers 0x03E9 (1001) and
0x03EA (1002).
Request is: 09 17 07 D0 00 02 03 E9 00 02 04 00 E6 3C C8 2D 0C
