5000 16 Fix | Rslogix

RSLogix 5000 Version 16 was a landmark release that introduced critical features like Add-On Instructions (AOI)

1. Upgrading to RSLogix 5000 v16: Users currently using earlier versions of RSLogix 5000 should consider upgrading to v16 to take advantage of the new features and improvements.
2. Training and Support: Rockwell Automation provides various training and support resources, including online courses, documentation, and technical support, to help users get the most out of RSLogix 5000 v16.

1. Use DINT for internal logic: Even if the source is 16-bit, move it to a DINT immediately and perform all math, comparison, and bitwise operations in 32-bit space. This avoids implicit conversion warnings and unintended overflows.
2. Mask the upper word: When performing bitwise logic on a value that originated as 16-bit, apply an AND with 16#FFFF after every operation to clear the upper 16 bits.
3. Use COP (Copy) carefully: The COP instruction copies based on destination size. Copying two INTs to one DINT will produce an unexpected result. Instead, use BST (Branch Start) with math or the CONCAT function (available in newer versions) to assemble 16-bit words into 32-bit.
4. Avoid INT arrays for large data: While logically clear, large arrays of INT consume more controller memory and scan time than an equivalent DINT array because the controller must manage boundaries. Use DINT unless directly interfacing with a 16-bit device.
