PLC programming excercise with solutions.

This section covers programmable logic controller, PLC programming examples. Every example program includes the description of the problem, the solution as well as PLC code, explanation and run time test cases of the problem. These examples can be simple PLC programs or advanced PLC programs. So, they are suitable for any user (dummies, beginners or advanced users).

Here is the listing of PLC programming examples for different categories viz. Digital logic, Home and Industrial automation.

1. PLC Programs on Digital Logic


This section of PLC programming examples cover various digital logic likes Logic gates, Boolean functions and combination logic circuits. It also contains PLC programs on converters like Binary to BCD to Excess-3 code to BCD to Gray code, etc. followed by Multiplexers, DE-multiplexers, Line encoders and decoders. It subsequently implements various Flip-Flop circuits like SR, D and T Flip Flops followed by PLC programs on Latching and Unlatching an Output by Time delays and Sealing.

Timer Functions: Timer functions are used to implement timing sequences. For example, waiting and monitoring times, measuring of time intervals, generation of pulses. The timer functions are stored in system memory of the CPU. The following timer types are available: ·          Pulse Timer ·          Extended Pulse Timer ·          On delay Timer ·          Retentive On Delay Timer ·          Off Delay Timer Timers have an area reserved for them in the memory of your CPU. This memory area reserves one 16-bit word for each timer address. The ladder logic instruction set supports 256 timers. Please refer to your CPU’s technical information to establish the number of timer words available. The following functions have access to the timer memory area: · ...

Basics of Configuring Hardware with Simatic STEP 7 (v5.5 & v5.6)

Introduction to Configuring Hardware. You configure the hardware in HW configuration. You can open HW configuration by selecting a station in the SIMATIC Manager and then double-clicking on the " Hardware " icon.   Configuring The term "configuring" refers to the arranging of racks, modules, distributed I/O (DP) racks, and interface submodules in a station window. Racks are represented by a configuration table that permits a specific number of modules to be inserted, just like a real rack. In the configuration table, STEP 7 automatically assigns an address to each module. You can change the addresses of the modules in a station if the CPU in the station can be addressed freely (meaning an address can be assigned freely to every channel of the module, independent of its slot). You can copy your configuration as often as you like to other STEP 7 projects, modify it as necessary, and download it to one or more existing plants. When the...

How to configure Racks in SIEMENS PLC

Configuration Table as a Representation of a Rack For a local configuration you arrange the modules beside the CPU in a rack and continue into additional expansion racks. The number of racks which can be configured depends on the CPU you used. Just as you do in a real plant, you arrange your modules in racks with STEP 7. The difference is that in STEP 7 racks are represented by "configuration tables" that have as many rows as the rack has slots for modules. The following figure shows an example of how a real structure is converted into a configuration table. The configuration table corresponds to the rack used; STEP 7 automatically places the number of the rack in brackets in front of the name. Example: (0) UR corresponds to the central rack (Universal Rack) number 0. Opening Objects in HW Config In STEP 7, you can open objects in order to edit them. In the SIMATIC Manager, for example, select the "Hardware" object and then select...
