STRING_OUTPUT

STRING_OUTPUT <var1>[,<var2>...];

STRING_OUTPUT <var[size]>;

STRING_OUTPUT <var[size[,<min>]][size]>;

Routes serial strings from the SIMPL+ program to the SIMPL program. A string 
length is not required as the output string buffer management is performed by the 
operating system. Refer to the discussion on arrays on 

The value of a STRING_OUTPUT cannot be read. If knowledge of the value of the 
STRING_OUTPUT is required, the value to be written to the STRING_OUTPUT 
can also be written to a STRING for local storage.

In X-Generation Control Systems, if several values are issued to a 
STRING_OUTPUT, the logic will only see the last value written to the 
STRING_OUTPUT when the SIMPL+ program task switches away. If all values are 
required to be seen by the logic, a PROCESSLOGIC statement is required after 
writing to the STRING_OUTPUT.

In the 2-Series Control Systems, all values written to a STRING_OUTPUT are 
maintained. The logic will see each value of the STRING_OUTPUT. No 
PROCESSLOGIC is required.

For an array of STRING_OUTPUTs, the maximum value of SIZE is 65535. Valid 
indices are 1 through the specified size.

NOTE: These outputs may be jammed with other serial string signals in the SIMPL 
program, although the value does not propagate back into the SIMPL+ symbol. 

NOTE: The maximum string length for a STRING_OUTPUT is 255 characters. 
Assigning a string with a length of more than 255 will result in a loss of data.

NOTE: You should use isSignalDefined to test whether the output is connected to an 
actual signal in the SIMPL Windows program before assigning a value to it. If you 
assign a value and there is no signal, a message is placed in the system error log.

NOTE: <min> is the number of outputs shown at a minimum in SIMPL Windows. 
The Default is 1. The user can expand the minimum up to the full size. Only the last 
array of a type can have <min>. Refer to Arrays on
