Hello everyone, I cannot access my digital outputs via RTDE., so, I have any doubts: 1 - There are two “functions” to access outputs? (standard\_digital\_output\_mask and standard\_digital\_output) . 2- Do they work the same way? 3- Can I choisse only one to use? 4- The variable’s type is UINT8. I must send a variable UINT8, for example, value = 127 (mask = 01111111). Is it correct? 5- I’m using the simulator, could this be the problem? I can send my package via RTDE, I can set input registers but never set the outputs. Thank you ---

Hello, I founded the solutions for my issues: Standard\_digital\_output: Value to set the Ports (0 - False and 255 - True) Standard\_digital\_output\_mask: Mask with Ports that you want to enable or Disable Example: I want enable Ports 2 and 3 Standard\_digital\_output = 255 Standard\_digital\_output\_mask = 10 10 is 00001100 on base 2
