Pointe Controller User Guide Appendix C: Ladder Diagram Block Reference
431
Functional Description
This block always passes the Enable input state (EN) through to the Enable Out
output state (ENO) without change; when EN becomes on, ENO is turned on, and
when EN becomes off, ENO is turned off.
When EN becomes on, the block function is executed: the Input Value (IN) is
converted into an equivalent string and the result is sent to the Output Value
(OUT).
For example, the numeric value 123 is converted into a three-character string
‘123’.
The block function is executed every time the ladder is scanned , so long as EN
remains on. If EN becomes off, then OUT remains at its last calculated value until
EN becomes on and the block function is executed again.
Configuration Reference
The parameters of this block are described in the following table:
Param Name Config Var Type Description
EN Enable no - The state of the rung (off/on)
received from the left.
ENO Enable
Out no - The state of the rung (off/on)
passed to the right.
IN Input
Value req any Input
any Memory
any Output
Numeric
String
The input value.
OUT Output
Value req String The result of converting the input
value into an equivalent string. The
output is always NULL-terminated.
NOTE: No restrictions are placed on the size of the output string. If the string
resulting from a non-string IN is longer than the defined Element Length of the
String variable configured to OUT, then a NULL string is placed in OUT. String-to-
string “conversions will simply truncate excess characters. In neither case will an
overflow error be generated.
