Step 5 stl manual

Proper orientation affects strength, build time and the appearance of the part. Depending on the shape, it might also make the difference between whether or not the part fits inside the modeling envelope.

To reduce build time, orient the part so minimal supports are needed. To give the best appearance for the part, orient it so the slices are layered one on top of another along a vertical plane.

The STL model is displayed inside of the build envelope in the front-left corner. The displayed envelope represents the size of the largest model that can be built on the selected machine. If the STL is inside the display envelope, it can be built on the modeler.

Available options include rotation, scaling, working units inches or metric , and Orient by selected facet. Orient by Selected Facet: This lets you select a facet of the STL model and a side of the modeling envelope to be aligned.

Then, click on the facet you want aligned with that side. The STL model is then oriented so that the selected facet will be parallel to and facing toward the specified side of the modeling envelope. The slice operation slices the part using the current values set in the slice operation panel. When the slicing operation is complete, it will notify you of any problems in the part curves.

The slice operation computes part curves by analyzing cross sections of the STL file. The size of the logic window may be adjusted. The corresponding Symbolic Library may also be displayed and edited at the same time. The size of the step boxes is adjustable to the size number of characters per line, number of lines of the used comments.

The status display has the same layout as the editor window. Active and corrupted steps are specially indicated.. Legal Notices Sitemap Privacy Search. S5 Programming. For automatic troubleshooting the S5 Doctor functions are integrated as well. A comfortable editor to create and edit symbolic tables is integrated.

Searching and replacing for any criteria as well as rewiring is possible. A syntax check is integrated. The new comfortable multiple segment editor for the creation of statement lists, function block diagrams and ladder diagrams allows the representation of complex functions too. In this window the symbol file can be edited simultaneously.

The allocation of new addresses with syntax check is integrated. Statement lists are created with the comfort of integrated editor. The Windows clipboard can be used for program or configuration manipulations in any place.

Statement lists can be altered into function block diagram or ladder diagrams, as far as they are displayable. Recorded videos can be shown synchronously to process signals and a recorded block status of the PLC with time stamp. With the Statusrecorder , dynamic procedures can be explored by subsequently analysis of the block status frame by frame. Statusrecorder PLC block status. Doing this without having the associated offline program open will cause a loss of documentation.

Save — Stores the open block onto the hard drive. Note that this only saves the opened block and not any others that are concurrently open. Nodes — Refers to any programmable device in our case a PLC in the network which will have its own unique address. The best practice is to make sure you are working from an offline file. Of course, this assumes that you have a good working copy to begin with. So where do some people get lost? Here are some common mistakes and their warning signs.

This is an example void of documentation. Notice the local parameters all say TEMP. There are no comments or titles. The properly documented copy looks like this The Display Accessible Nodes selection under the PLC menu is a handy way to see what is connected to the network but it should never be used to open blocks. Opening blocks from here uploads it straight from the PLC and produces the warnings dialog boxes shown above.

Once a project is open and a connection to a PLC is established then selecting the Online button menu View Online brings up a similar project tree showing the contents inside the PLC. The window title bar is highlighted in blue to indicate its online status.

Working from this window presents less of a danger for losing documentation but it is confusing and could lead to problems. For instance if a block is renamed offline and then the old one is opened online then it will have no associated documentation. The proper way to view a block online is to open the block and select the Establish Connection to Configured CPU icon.

Just make sure what you are viewing has been downloaded to the PLC. Essentially this puts you in the same place as pitfall 2.

Always working from the offline copy will make it less likely to screw up. Opening up a block from the accessible nodes window is always a no-no. Likewise, opening a block from a window that has a highlighted blue title bar will also cause potential problems. Avoid the pitfalls and keep that documentation. Mystery solved. These warnings are especially crucial if you are working on real machinery. Click the General tab and press the Activate button.

I couldn't find a complete listing of all the function blocks in the standard Siemens S7 Libraries so I made one myself. It helps me get a better overview of what is available. The complete listing is also available as an Excel spreadsheet so you can sort or adjust to your needs. Otherwise known as Siemens speak. Here's a list of Siemens specific abbreviations and their meanings. The following is provided by Automation Training from their excellent Siemens Step 7 training manual.

This is a really nice explanation of a difficult but important subject. Check out their website for hands-on and online training classes. When a direct addressed is referenced by an instruction there is no question as to the location in memory.

The following are examples of direct addressing:. By using the methods of indirect addressing the address used by an instruction can be varied to point to any number of locations. While this may increase the difficulty of troubleshooting, its advantage is to greatly reduce the number of networks and instructions needed to control a process. It is also a method that must be understood to use some of the library and system function calls provided by Siemens.

A pointer is always preceded by a P symbol. The pointer address may be in three different formats. The ANY data type is used to pass a parameter of an unknown or undefined data type. Some functions in the library use the ANY data type to work on whole sections of memory. To do this, the last pointer method is used to describe an area. For example the address P DB DBX 0. When working with indirect addressing it is sometimes needed to first of all open a DB and then begin working on the address without directly referring to any one DB.

This is done using the OPN instruction. Furthermore, there are instructions to confirm that the correct DB number is opened and that it is large enough for the next operation. The first method of indirect addressing is called memory indirect addressing because it allows for a memory location M, DB or L to determine or point to another.

Two examples are as follows:. Since the bit position only goes to eight the result of P 8. Besides the regular accumulators, there are two bit address registers AR1, AR2 for storing pointers used in register indirect addressing methods. A series of different load and transfer type instructions can be used to work with AR1. A similar set is available for AR2. The area-internal register indirect addressing method uses one of the address registers plus a pointer to determine the address the instruction is to reference.

The format is:. The address register must be previously loaded with a double word pointer without reference to the address identifier. The exact address is determined by adding the address register with the pointer. The example below shows the area-internal method using bit locations. Area-crossing register indirect addressing is similar to the area-internal method except the pointer loaded into the address register references a memory area e.

This means the address identifier used before the opening bracket is not needed if referencing a bit otherwise it will be a B for byte, W for word or D for double. The example below shows the area-crossing method using bit locations. The RLO bit stores the running logic state of the currently processing instructions. If you are used to ladder logic and struggling to understand the purpose of the RLO and STA it may help to visualize a rung like below. The OV bit is set by a math instruction with floating point numbers after a fault has occurred overflow, illegal operation, comparison unordered.

The OV bit is reset when the fault is eliminated. The Binary Result transfers the result of the operations onto the next instruction for reference. The programming is done with very simple mnemonics that can be hard to remember if you don't use it very often.

These cheat sheets provide a quick reference guide for all the instructions and formatting. They are two pages long but if you can print on the front and back then they make for a nice one sheet reference. Close all other running applications, including any antivirus software you may be running.

This step involves using the Commissioning Wizard to configure the software you installed in the previous step. When your system restarts after the software has been installed, your system's hardware configuration is scanned. The Commissioning Wizard appears automatically. The number of steps required depends on the number of PC Ethernet cards or modules detected in your PC.

The more modules you operate in the computer, the more steps are required. The following points are needed:. If you have experience with Siemens then please contribute. Order the demo CD which will give you a free day trial period.
