Converting Ladder program to Structure Text

[alikambali 0]

Hi,

I'm new in Omron Sysmac Studio programming and hereby kindly need some advise related how to write an ENO output in "Structure Text" type.

I have a CONCAT function which if the process is "no error (eg. string length)" then output of ENO will set a variable. pls see below sketch.

 

         Start                ____________________                             Complete

----------| |---------------| EN    CONCAT     ENO |---------------------------( S )------|

                   String1--| In1                                 |--NewString

                   String2--| In2                                 |

                                 ----------------------------------

 

any idea most welcome.

ENO just means the CONCAT FB executed.  So, in your structured text, right after the CONCAT structured text command executes, just set the variable on.  You can set the string to null prior to the concat and then make sure it is not null prior to setting the bit on.
