CHAPTER 7 PROGRAMMING INTELLIGENT FUNCTION MODULE
7.1 Intelligent Function Module
(1) Intelligent function module type
On programmable controller CPUs (hereinafter referred to as QCPUs), some
functions are not supported or are limited in use. Intelligent function modules
support those functions instead of QCPUs.
Therefore users need to select an intelligent function module that is appropriate
for the purpose involved.
QCPUs are compatible with QCPU-compatible intelligent function modules.
The following table shows examples of the intelligent function modules.
