assignment list for S7

Is there anyone who knows the *.asc format for S7 plc?

Is the data length of 126 characters fix or can it be variable?

Hi..

The maximun chain of character (date string) is 254 character (date type CHAR). The chain can use only like unity.

The standart area is reserved for 256 bytes (254 char)
(1 byte= 1 character + 2 byte for begin)
You can make exact chain of character like this:
(p.ej.: string[9] 'Siemens').

Hope this help.
