6.6.7Digital outputs

Introduction

This chapter contains the specifications for the digital outputs of CPUs 31xC.

The table includes the following CPUs:

•under CPU 313C-2, the CPU 313C-2 DP and CPU 313C-2 PtP

•under CPU 314C-2, the CPU 314C-2 DP and CPU 314C-2 PtP

Fast digital outputs

Technological functions use fast digital outputs.
