  • Page 13: Hardware Overview

    Conjunction with Anybus, it interfaces with most industrial network protocol such as Profibus, Profinet, Ethernet/IP, CC Link IE, and etc. The SCM4-PLM module receives and stores digitally converted analog data into its image table for retrieval on a Serial or a PLC network. The module supports connections from four strain gage sensors.

    CHAPTER 2 Chapter 2 Getting Started This chapter can help you to get started using the Helm SCM4-PLM module. The procedures included here assume that you have a basic understanding of PLC Network communications. You should understand electronic process control and be able to interpret the ladder logic instructions required to generate the electronic signals that control your application.

  • Page 18: System Operation

    Instruction Manual CHAPTER 2 System Operation The SCM4-PLM module receives+24Vdc power from an external power supply to operate. Each individual channel on the module can receive input signals from strain gage based sensors. The module converts the analog values directly into digital values.
