The main objective of this course is to provide a novice understanding of Allen Bradley PLC programming, ladder logic, and familiarize enough with a variety of ladder logic instructions to develop a PLC program.
This training course designed for the engineers who are interested to learn the basic Allen Bradley PLC programming using RSLogix500.
› Online Integrated Development Environmentįrequently Asked Questions What is rslogix500 training course?.This is why the addressing for the Logix5000 is different than other address-based PLCs when it comes to creating tags in NI OPC Server. Instead, the tags are abstracted into their tag names. The Logix5000 PLC uses tag-based addressing, so there are no address locations used to identify where each tag is located. Navigate to Allen-Bradley ControlLogix Ethernet > Address Descriptions > Logix Tag-Based Addressing > Address Usage > Logix Advanced Addressing.Select Allen-Bradley ControlLogix Ethernet > OK.If the tags are not reading in correctly in Quick Client, check the Driver Help to make sure your syntax is correct for the Data Type used:.Open Quick Client to check that the array is being read in from the PLC correctly.For example, if FlowArray_x had 50 elements in it, the address will look like Program:MainProgram.FlowArray_x. Replace it with curly brackets and the length of the array within the curly brackets.
Delete the square brackets and number within the square bracket.Based on the image in step 2, that would look like Program:MainProgram.FlowArray_x. In the Tag Properties window, paste in the address you copied from step 2.Right-click on the Device in NI OPC Servers and create New Tag.In the image from step 1, you would copy Program:MainProgram.FlowArray_x Copy the address field of this array-element tag.For example, if we had an array called FlowArray, we may see something like the image below. Since you already have auto-generated tags in NI OPC Servers for the array of interest, open up one of the tags for an element of the array.
