Is there a simple example of a CREAD_REG function for TCP/IP communication.
Issue
The Ethernet communications can be confusing to program using Unity, since they vary from PAC family to family. This is one of a series of example applications that presents each function block in a working version for the user to build on.
Product Line
Quantum, M580, Control Expert, Unity Pro
Environment
Windows 7, Windows 10
Resolution
The attached application cread_reg.zef will continuously read ten registers from another device (using the CREAD_REG function block). The application consists of two sections. The first is an ST section in which variables are initialized. The second section, which is the example proper, is a LD section which uses CREAD_REG function block to read10 registers to another device, the server. The IP of the server is 192.168.1.30. This should be changed to suit your own addressing schemeThe application is annotated and should provide a start for the user of the CREAD_REG block. It is up to the user to change the PAC type and IP addresses to meet his or her own requirements. There is both a .zef and .xef version in the zip file.
