 Allen Bradley 1756-L72SK ControlLogix Controller

Just like other Logix processors during development, safety and standard have the same rules. Online editing, forcing, even multiple users are all allowed. Once the project is tested and ready for final validation, you set the Safety Task to a SIL 3 integrity level, which is then enforced by the GuardLogix controller. When safety memory is locked and protected, the safety logic cannot be modified. On the standard side of the GuardLogix controller, all functions operate like a regular Logix controller, motion, drive, sequential, even process. Thus, online editing, forcing, and other activities are all allowed, while safety is securely isolated.

How to CPU in a dual processor motherboard?

One question we get asked at least one time each week is whether or dual socket motherboards meant for dual processors can work with one CPU. A common driver behind this question is because dual processor motherboards allow for easy expansion at a later date. Add a second CPU, heatsink/ fan and additional memory to a system without replacing any internal components or adding a second machine. The answer to the question “Can I use one CPU in a dual processor motherboard?” is yes… with some caveats. Let’s explore why. The vast majority of motherboards “just work” if you install a CPU into the lowest numbered CPU slot. This is usually CPU0 if there is CPU0 and CPU1 or CPU1 if the board is tagged CPU1 and CPU2. This is true for both Intel and AMD motherboards in general and when in doubt, most motherboard manuals will instruct a user as to which processor slot can be populated by a single CPU and a dual CPU motherboard. Here is an example from an ATX X79DUAL motherboard tha...

  Hello, friends. Welcome to Joinwin Blog. Today we would like to talk about a hot FAQ from our customers. As you known, Joinwin provide life time warranty about ram memory. We are very confident about our ram quality. We always said we use original 3 RD chips. Quality is one thing we never compromise. So, many friends will ask us, how do you guarantee that? How do you test the ram? Do not worry. In our ram manufacture, we will have three times QC. After finishing manufacture, we will have appearance inspection. This is the first time QC. Then after PCB board cutting and information input, we will have a second QC. Here I would like share you a equipment list about our daily testing of ram memory.  DDR2,DDR3,DDR4 RAM modules Is it great? I think through this testing equipment list, you will have a better understanding about Joinwin ram testing. After testing on motherboard, we will do cleaning, spot testing before delivery. This is the final QC.Then we ship bea...

  Hello, friends. Welcome to Joinwin Blog. Today we would like to talk about another product motherboard. This is also a popular product from Joinwin. Our motherboard factory is located in Longhua district, Shenzhen. The motherboard PCB is all solid state. It means it will work more stable. Besides, our chip set only use original Intel. This is the most important and expensive part of whole motherboard. Good PCB and high quality chip are the basic of whole motherboard. Secondly, most of our CPU socket covers are from Foxconn. You can see this Foxconn logo. Because in our experience, customers like Foxconn quality a lot. Although Foxconn covers actually expensive a little, we will also choose them. In the production, we will have three times QC. If you buy our motherboard, you can see QC label on the back side of PCB. According to that QC label, if have defective parts, we will easily to know which worker was responsible of it. From this...
