Practical Tips and Techniques
A majority of programmable logic controller (PLC) programs will include a counter instruction. The Productivity 1000 Series PLC has a couple of different counter instructions for your program. Under the data handling instructions, we have the increment/decrement instruction (INC). We could use this with the compare contact (CMP) instruction that we discussed in our Contact … Read more
Just about every programmable logic controller (PLC) program will include a timer instruction. The Productivity 1000 Series PLC has several different timer instructions for your program. We discussed the timed coil (TMC) and flasher coil (FLS) last time as part of the contacts and coil discussion. (Contact and Coil Instructions – Video) We will now … Read more
Contact and coil instructions are in every PLC program. The Productivity Suite Software consists of more than 82 instructions divided into 13 categories for the PLC. Contacts and Coils are two of the categories of instructions. Contact instructions include NO / NC, NO Edge / NC Edge and Compare. Coil instructions include Out, Set, Reset, … Read more
We will now look at the tag numbering systems used with the Productivity controller. The Productivity Suite Software allows us to use tags in the PLC. Tags are a method for assigning and referencing memory locations (numbering systems) within the programmable logic controller. They allow a more structured programming approach and are stored within a … Read more
The Productivity Suite Software allows us to modify our existing program and execute the new code without stopping the scanning of the PLC. This is referred to as online editing. We change the ladder logic code and when we save it to the PLC, the current scan of the PLC is held until the new … Read more
We will now look at monitoring and testing our productivity program. The Productivity Suite Software provides tools for us to monitor and test our programs. Last time we used Tag Names and Details, Task Names and Descriptions, Rung Comments, and Instruction comments to document our first program and transferred this to our connected Productivity 1000 … Read more
Last time we created our first program and transferred this to our connected Productivity 1000 Series PLC. This was programmed with our computer running the Productivity Suite Software. One of the most important aspects of programming the PLC is to document. This will aid you and your team in programming, troubleshooting, and modifying the automation … Read more
We will be connecting the Productivity 1000 Series PLC with our computer running the Productivity Suite Software. A micro USB and an Ethernet (RJ45) communication link will be made to our programmable logic controller. The latest Productivity Suite software version is 3.1.0.11. This is the programming software that we will be using to create our … Read more
The Productivity 1000 series of programmable logic controllers has a slim stackable super compact design. This is sometimes also referred to as a shoebox PLC because of the shape and way in which expansion modules are added. This new Productivity 1000 series PLC is the latest in the Productivity series of controllers that have hit … Read more
We will now look at shifting instructions in the BRX Do-More controller. PLC shifting instructions will move bits in memory areas a fixed amount when instructed. Bits are on/off, 1 or 0, and are usually associated together to form a memory location. The memory location can be used for numbers or positions. PLC BITS NUMBERS … Read more
