Three steps to solve the problem of TCP/IP network controller communication failure
TCP/IP network controller communication is not available
1 Check if the controller network light is on.1. Check the network light: the green light (LINK) is always on, and the orange light (ACT) is blinking normally.
1. Turn off the firewall;
2. Disable the wireless network card;
3. Download the latest version of the corresponding model software;
4. Connect the controller at close range for testing.
1, search controller;
2. Set controller parameters;
3. Add controllers by means of cross-network segments;
4, enter the [total console] detection controller (detection controller, real-time monitoring, uploading, etc.) communication is normal.
Tips
1. It is possible to test whether the controller communication is normal in a small network; 2. Configure it in a small network, and then put it into a large network for use; 3. If the corresponding network is not proficient, you can ask the on-site network management to assist in troubleshooting.
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
