Programming Methodologies and Total Cost of Ownership

Programming Methodologies and Total Cost of Ownership Introduction If you have ever been involved with or had to fund a new application or an upgrade to an existing application and experienced excruciating pain (cost, duration, delays, …) in the process, then you might be interested in this. Carpenters have a saying – “Measure twice, cut once”.  It’s not quite the same, but planning out how the system should operate and perhaps as importantly what you want to prevent it from doing and even more important how to recover from an “abnormal exit” is ‘required thinking’.  Just for clarification, I am calling an abnormal exit some sort of ungraceful and unplanned stoppage for the system.  That could be a power outage or perhaps a drive failure or a chain breakage or an E-STOP or ……………. Break It Into Chunks (Modular) Just as you eat an elephant one bite at a time, you also have to tackle a large solution one sub-system at a time. I need to point out that this is not a treatise on “modular programming” in its purest form which is defined as “a software design technique that …

Batching Best Practices

Batching Best Practices INTRODUCTION This intent of this paper is to present a few Best Practices I have discovered over the years that lead to an improved performance of ingredient automation (batching) systems. LOAD CELL INSTALLATION Site Preparation All mounting surfaces for the base and loading plate must be level. The distance between the mounting surface of the loading plate and base must within 1/32” of the nominal height (for proper elevation of vessel). The Load Cell Assemblies in a system must be level to within +/- 0.5 degrees. When mounting the base plate on concrete, use grout to secure the plate after leveling. A classic 4 bolt system with anchor bolts embedded in the concrete foundation with nuts above and below the sole plate are used for leveling both within the sole plate and between sole plates. Any welding should be done prior to installation of the load cells. Proper drainage should be provided to prevent the load point assembly from standing in water. Installation All load cells must be on the same plane (level) within 0.5 degrees of each other (which is approximately an …
