Siemens S5 overflow in data exchange

[ausward]

Hi all, I am using a MSDOS laptop to communicate with a siemens S5. I get an error Overflow in data exchange with pg and am unable to go online. Any ideas? Dos 6.22, S5 ver 6.65

I have seen this kind of message in two situations:

• when a student was trying to communicate without a current loop converter between PC and PLC
• when a student did change the port settings of the PC.

Hope this may help.

Kind regards,
