Sometimes when using the PC / ISaGRAF debugger to connect to the ISaGRAF controller will pop-up a
window like "Can not link ..." or "Can not download" or "Can not find BMP ..." or ...
To solve this problem, please do below steps.
1. First close all ISaGRAF windows. Then press and hold on "Ctrl" plus "Alt" key and then press "Delete"
key to open the Task Manager.
2. Stop the process which is with empty memory. Then run PC/ISaGRAF again to connect to the
controller.
3. If the problem is still there and you are using Ethernet to connect the controller, check if your PC and
controller are set in the same IP domain. For example, PC with (IP, Mask) = (192.168.1.2,
255.255.255.0) cannot connect controller = (192.168.3.5, 255.255.255.0). However it can connect
the controller = (192.168.1.5, 255.255.255.0) well.
4. If the problem is still there and you are using RS-232 to connect the controller, check if your RS-232
cable is correct and check if you are setting the correct PC RS-232 port number to connect the
controller.
5. The last way is re-start your PC and try again.
