I have an automate S7-300, an automate S5-95U, and an automate S7-200 which is linking the S5-95U to the S7-300. I can connect to the S7-300 directly though IBH Link S7++. But, I cant connect to the S5-95U though IBH Link S5++ because I can't plug it to the S5-95U because the plug is already taken by the S7-200 (the one doing the link with the S7-300). So, I tried to connect to the S7-200 to reach the S5 but when i plug the IBH Link S7++, I have an error message : "error 5994" [S5W]. I can't use the IBH link S5++ on the S7-200 because its doesnt match. What can I do? Do I have to unplug the S7-200 from the S5 and then plug my computer to change the program? What does the error message mean? If you have any idea please tell me
.I hope you would be able to help me. Thank you for your time !
Ps: I hope I was clear explaning my problem.
