The system flow chart of serialĬommunication between Panasonic PLC and PC in C#.NET environment is shown in figure 2.1 With this control you can easily achieve serial communication.
SerialPort has been significantly optimized than the previous NET has been upgraded to SerialPort control.
#OMRON PLC SERIAL COMMUNICATION PROTOCOL SOFTWARE#
In the past, the software of communication with industrial PLC in Windows environment is MSCOMM control in VB6.0,īut in. THE REALIZATION OF THE COMMUNICATION PROGRAMMING Its initial value is “0”.Then bitwise exclusive OR from the initial bit to theįrame message in each byte. ”#”,”$”,”!” marking the type of the frame message, for which the correspondingĪs follows: command information, response information (normal), response information (error). ”AD” is each PLC station address, represented by two hexadecimal numbers. 2.2 Communication sent formatĢ.3 Communication sent format specificationĪmong them,”%” is the starting symbol, marking the beginning of each frame message. Its communication sent format is like this. First, the computer sendsĬommand, PLC responds appropriately to the command. Panasonic PLC communicates with PC through RS232. PANASONIC PLC COMMUNICATION PROTOCOL 2.1 Communication process Therefore, it’s very important to realize the communication of Panasonic PLC and PC in the C#.NET environment.
In many measurement and control system, we need to combine other procedures developed for C# with PLC control, to make the system not only can collect and store data in time, but also for advanced data processing, to achieve the integration of measure, control and management and better complete the operation. NET development with powerful operation ability and innovative language features. In the software development industry today, combined the visual operation of VB with the efficiency of C++, C# becomes the preferred language of. Though configuration software is convenient, we need to pay the high cost of software, and secondary development is limited. Communication between PC and PLC is realized in two ways, which are configuration software and high level language.

Therefore, we need to make up for these shortcomings and give full play to its performance with the help of communication between PLC and PC. But it also has the disadvantages of poor data management ability, can’t provide humanized interface etc. The Panasonic PLC, with its perfect function, small size and low price, are increasingly applicated in the modern industry control system. In the control system, more and more people using PLC as the controller, which is more convenient, especially in the aspect of position, speed and torque. In this respect, measuring and testing technology will play a more important role and get greater development.

It's too slow and must manage various commands. When i try to modify only one bit in a complet register, first must read the complete register, to modify the value and write the new complete register. I ( to read a register ( to read holding ( to write register ( to write holding ) When i have a response, can't know what's command is replying the PLC. Īctually, when i send a command, sometimes i send various command to PLC ( by multithead ).
My first problem is to manage multithreading. I need a DLL to comunicate with omron CP1E PLC by serial communication.
