6PLC Programming Using RSLogix 500 - Advanced Programming Concepts, is the 2nd book of this series. It is meant to provide a practical guide for developing your knowledge of ladder logic instructions and the skills necessary for building control systems for machinery or manufacturing processes. Advanced Programming Concepts builds on instructional elements covered in book one, and illustrates the usage of the more advanced techniques and instructions used in ladder logic programming.In Book 2 of this series you will learn: -How to configure RSLinx communication protocols, drivers and networks.-How to effectively use the OSR, OTL, and OTU output instructions.-The use of timers, counters, and retentive timers; and how to cascade timers and counters to achieve longer, more precise time periods for special needs.-How to configure and address commonly used math, comparison, logical register, and program flow instructions.-What analog scaling is all about and why it is necessary.-How to do the math involved with scaling instructions.The main objectives of the author are to provide a practical resource for those new to PLC's and ladder logic programming. Learn the skill necessary to do your own programming and be able to quickly go online with the PLC controllers on the factory floor for troubleshooting purposes.
