Have you read some of the customer case studies on our website, or seen a case study video, like the one at left for New Belgium Brewery? Case studies are a great way to get ideas about system design.
Your company can be featured in a case study, too. Case studies showcase your successful automation system design and provide publicity for your products and services.
Opto 22's Case Study Program offers four levels of participation, from a simple paragraph to a combination of written and videotaped case studies that appear in trade publications. You retain complete control over content and distribution. For more information, read about the Case Study Program.
"Recently I was helping a customer who was having trouble creating a text file on the FTP server of our controllers," one of our Product Support Engineers told OptoNews.
The problem was formatting the text file so that the data would show up on separate lines.
The customer needed data in this format:
LINE NUMBER 1
LINE NUMBER 2
LINE NUMBER 3
LINE NUMBER 4
LINE NUMBER 5
But he kept getting the data in a continuous string, like this:
LINE NUMBER 1 LINE NUMBER 2 LINE NUMBER 3 LINE NUMBER 4 LINE NUMBER 5
The solution was to append both carriage return and line feed characters to his string statements, BUT they had to be in the correct order: first the carriage return (ASCII character 13) and then the line feed (ASCII character 10).
The solution looked like this:
PAC Control flowchart example:
Append Character to String
Append 13
To STRING_STATEMENT
Append Character to String
Append 10
To STRING_STATEMENT
OptoScript code example:
STRING_STATEMENT += Chr (13);
STRING_STATEMENT += Chr (10);
Once the carriage return and the line feed were put in the correct order, the odd effects he'd been seeing disappeared, and all worked correctly.
