C.9.6 Integer to Character (TO_CHR)
When used in a Ladder Diagram, the TO_CHR block converts a decimal value into
the equivalent ASCII character.
Select the tool (from the Miscellaneous Blocks toolbar) and click on a ladder
rung to insert the following block:
Once the block is inserted, you can double-click on it to configure it.
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 ASCII character and the result is placed in the first
character position of the Output Value (OUT).
For example, the decimal value 65 is converted into the ASCII character ‘A’.
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

received from the left.

passed to the right.
