Byte x+4 to x+7 (x+10) for diagnosis of ET 200X
If byte x+2 contains the slot number 02, this indicates that a basic module is
generating diagnostic messages. These diagnostic messages are contained in
bytes x+4 to x+7 (x+10).
Table 5-22 gives you the meaning of bytes x+4 to x+7 (x+10) when the following
basic modules are used:
