C and T involve two types of data: current value and set value. Cn and Tn represent the current value and can only be read and cannot be modified by the periphery.
It is possible that the COM port is not selected, it can be set in the text editing software, or whether other programming software is open, which will occupy the COM port. Or the text editing software version is incorrect.
Xinjie programming port is RS232; Xinjie has a matching communication line.
There is a COM port on the computer that has a download line that can be connected directly;
The editing software can be downloaded from the Xinjie website.
The text editing software can not be used casually. It needs to be based on the hardware of the text display. For the specific hardware version, please see the back of the text display. After each model, there is a text wrapped in an ellipse, such as V8.0. V6.5 and so on, this is the hardware version. For the software, the editing software version used for hardware version v4.0 to V7.0 is V6.5Z version, and the hardware version V7.0 or higher is used for editing software of V8.0C.
Op320 version 6.5Z The following reasons are as follows:
1: Communication with the slave (PLC or instrument) is interrupted. It is always in the connected state. No other operations can be performed. The button will not work.
2: The configured PLC or register address of the slave is incorrect and cannot be read correctly. The result is the same as above!
1. Do you see if the range of devices used in your screen exceeds the scope of the PLC?
2. Check if the station number of the device of your text screen is No. 1, default No. 1
3. Check if the plc port and your computer can be connected. If you can check your line pair is not right.
4. All of the above are excluded and sent back for repair.
The combined control requirements of the two motors: M2 is allowed to start 2 seconds after the start of the M2: Only after M2 stops 10S first, M can be manually stopped: In addition, M2 will stop working after 3 starts and stops, and the MI can be started separately. stop.
X0=M1 starts, X1=M1 stops, X2=M2 starts, X3=M2 stops, Y0=M1, Y1=M2.
OUT T0 K150.
A/S indicates the number of steps of the corresponding device using the normally open contact in the ladder diagram;
B/D normally closed.
D is the data register, and the internal is to save the data.
K is a decimal constant.
= D5 K6 means that when the data in data register D5 is equal to 6, the instruction turns on and runs the following instructions.
Enter Tx Kxxx
That is, x of x is the time relay number. Kxxx is the timer time, the unit is millisecond. For example, if you want to input the timer time is 20 seconds, the input value is 200.
If you want to use the 3rd timer and the timing is 20 seconds, the input format is: T3 K200.
1,Simulation – Monitor mode – Click – Write mode – Modify your program to be modified – Click – Compile – Click – Write to PLC
2, click F2
Y0 pulse, Y1 direction, D2 is the walking speed, D4 is the reset speed, D2, D4 is given by the upper computer
X0 is the manual automatic selection. When automatic is selected, the X1 conveyor roller is automatically operated. When manual is selected, the conveyor roller is manually operated after pressing X2. Y0 is the conveying roller operation.
TO is the output mode (current or voltage) of the set module, and FROM is the output command of the analog module.
M8013 is a 1 second clock oscillation pulse, Y1 is the alarm output (flashing alarm).
Need to have an electrician, assemble secondary lines, and understand the basics of various relays.
Learning the PLC can be done as follows:
1. Buy this book about PLC, learn about electrician knowledge, understand the electrical appliances, and go to control and understand various actuators.
2, is to understand the working mode of PLC, find a PLC, according to the example on the book, consider a small project, to achieve a function.
3, practice the true knowledge, understand the corresponding process, do a PLC project independently, the project is completed, the PLC will also master the Siemens 200 series of small PLC is very suitable for novice learning, easier to get started.
The conditions for self-learning PLCs should be as follows:
1, you have to learn programming software PLC (such as Siemens, Delta, Omron, etc.), each brand of PLC its programming software is slightly different, so what software to prepare what PLC.
2, it is best to reserve an HMI (Human Machine Interface), because PLC often needs to do some configuration control, it is really not good to achieve this, of course, now a lot of two in one, you can prepare a two-in-one device it is good.
3, a set of PLC programming software and HMI programming software
4. Relevant circuit design knowledge.
you can Add a timer to stop.
