EtherNet/IP Adapter Data Group Configuration: Using Strings
Any String data types will be mapped to a String Assembly and will not display in the input/output data
groups. The String assembly connection parameters will always be displayed.
When using a String data type, the first byte is set aside for the length. Each String (String 1 Port, String 2
Port, String 3 Port and String 4 Port) may have 99 characters.
When using String 1 Port, use Input Assembly 101/Output Assembly 113 where Byte 0 would be the
length and Byte 1-99 would contain the data.
When using String 2 Port, use Input Assembly 102/Output Assembly 114 where Byte 0 would be the
length of String 1 and Byte 1-99 would contain the data of String 1 and Byte 100 would be the length of
String 2 and Byte 101-199 would contain the data of String 2.
There is similar behavior when using 3 and 4 Strings.
