Technical requirements
Similar to the previous chapters, the only technical requirement you will need to follow along with is a working copy of CODESYS. This chapter will expand and modify the HMI from the last chapter; as such, you will want to pull down that HMI or review Chapter 11, or build one from scratch. You can pull down the code for this chapter at the following URL: https://github.com/PacktPublishing/Mastering-PLC-programming/tree/master/Chapter%2013.
