Model CSE331 and CSE340 Modular CPUs
The CSE 331 CPU (IC693CSE331) and CSE 340 (IC693CSE340) CPUs are single slot modules
which must be installed in slot one (labeled CPU/1) of a CPU baseplate (IC693CHS391 or
IC693CHS397). An illustration of the State Logic CPU modules is shown below.
Figure 9-7. CPU Models CSE 331 or CSE 340
The CSE 331 and CSE 340 CPU modules provide the same functionality as the models CSE 311,
313 and 323, and offer several more advanced features such as more I/O points and more User
Program memory. See the table at the end of this chapter to compare CPU specifications.
