Printco – Custom Printer Addition

Introduction

Although multiple brands of PLC’s were utilized by the various OEM’s for this production line, standardized use of the PROFINET protocol allowed for coordinated operation of the equipment. Implementation of Siemens PN/PN couplers allowed for ease of integration while maintaining segregation between individual machine networks.

Use of a Siemens S7-1500 Fail-Safe Technology CPU and S120 servo drives allowed Sure Controls to provide a solution that met the end users’ performance and safety specifications. Enhanced safety operations such as Safe Stop 2 (SS2) and Safe Limited Speed (SLS) over PROFISafe allowed for ease of machine operation while maintaining a high level of safety.

To follow an absolute position reference from the die-cutting section of the machine, a Siemens TMPosInput (Position Input Technology Module) was added to the S7-1500 Technology CPU to allow for synchronous, absolute positioning between the web-fed material and flexographic plate cylinders.
