In this post, we compare the SLC-500 family to the preferred migration product family, the CompactLogix processor.
When Allen-Bradley released the CompactLogix 5380 controller it boasted significant performance improvements (+20% capacity and 5-20x faster scan times) over previous CompactLogix models. This performance is orders of magnitudes faster and more capable than the SLC-500 platform. For an in-depth comparison, we will compare system architecture, memory, scan time, I/O capability and power connections.
