SEND
If SEND = TRUE, the user-defined diagnostic message is sent to all logged-on
stations. The message is only sent if the station is logged on and if the send buffer
is not full. The sending of the element is asynchronous to the user program.
EVENTN
The EVENTN parameter contains the event ID of the user event. You can enter
event IDs of the types W#16#8xyz, W#16#9xyz, W#16#Axyz, W#16#Bxyz.
IDs in the format W#16#8xyz and W#16#9xyz belong to predefined events, IDs in
the format W#16Axyz and W#16#Bxyz belong to freely defined events.
An event entering the state is indicated by x = 1, an event leaving the state by
x = 0. With events in class A and B, "yz" is the message number assigned to the
message in the message configuration in hexadecimal format.
The structure of the event ID is explained in Section 26.1.
INFO1
The INFO1 parameter contains information that is one word long. The following
data types are permitted for INFO1:
WORD

ARRAY [0 to 1] OF CHAR
You can integrate the parameter INFO1 as an associated value in the message
text and therefore add up-to-date information to the message.

data types are permitted for INFO2:
DWORD
DINT
REAL
TIME
ARRAY [0 to 3] OF CHAR
You can integrate the parameter INFO2 as an associated value in the message
text and therefore add up-to-date information to the message.
