How to establish communication between computer and s7-200 with usb-ppi cable

1. Power on the CPU Connect the CPU and computer
2. Open the programming software and click Set PG / PC Interface in the lower left corner
Note here:
(1) If the original Siemens USB-PPI, then select PC / PPI CABLE (PPI)
And set to USB in the properties local connection
(2) If it is a non-Siemens USB-PPI, then set the corresponding COM port in the attribute local connection, such as: COM3, etc.

Mitsubishi PLC programming line USB-SC09 and USB-SC09-FX difference

The difference between Mitsubishi PLC programming line USB-SC09 and USB-SC09-FX is:
1. USB-SC09-FX is only used for Mitsubishi FX series, and USB-SC09 is used for Mitsubishi FX series and A series.
2, USB-SC09-FX technology price is 140/10PCS, USB-SC09 technology price is 150/10PCS.
3. The USB-SC09-FX cable has a length of 2.5 meters and the USB-SC09 cable has a length of 3.0 meters.

Why is the USB-SC09-FX data cable for Mitsubishi FX1N-24MR PLC not connected?

After installing the driver, plug in the programming line, right click “My Computer” – “Properties” – “Hardware” – “Device Manager” – you will see “Port (COM and LPT)” in the open Device Manager window Open “Port (COM and LPT)” and you will see the COM port occupied by your programming line.

Open Mitsubishi programming software GX Developer, click menu “Online” – “Transfer Settings”, select RS-232 (not USB) in the “PC I/F” of the transfer setting, COM port is the COM port occupied by the programming line, transfer Speed is optional (default is 9600 in device management). Confirm

Usb-sc09 driver supports win8?

1. Right-click on the blank space on the desktop, and the “All Apps” option will pop up below the desktop. Left click on “All Apps”.
2. Left click on “Control Panel”.
3. The second type enters the “Control Panel” method. Press the “Windows” and “X” keys on the keyboard at the same time and click “Control Panel”.
4. Left click on “Hardware and Sound”.
5. Left click on Device Manager.
6. Left-click on the device class to be updated, right-click the device name, and left click on “Update Driver Software”.
7, update the driver can choose to automatically update online and manually specify the driver location update, select automatic update below.
8, the system will automatically find matching driver installation online.
9, update the driver can choose online automatic update and manually specify the drive location update, the following choose to manually specify the drive location update.
10. Click “Browse”.
11. Select the drive location directory and click OK.
12. Click “Next”, the system will automatically install the selected driver, and the installation steps are completed.
Step 10, please select the directory where the device driver is located according to the actual situation.

Usb-sc09 driver

USB-sc09 is connected to the computer and PLC, the driver is installed, how can I not connect?

USB-SC09 is the programming cable of Mitsubishi PLC. Before using it, you must first install the driver of the programming cable. After the installation driver is finished, you need to make a simple setting.
The setting method is as follows.
1. Right click (My Computer) and click Properties. The (System Properties) dialog box is displayed, select the hardware, and click (Device Management).
2. Select (port), find the USB port you installed, right click to display (property) click, display the property dialog bar, select (port setting) to set the COM port of the advanced setting in this dialog box to be the PLC programming software. The settings in it are the same.
3, the baud rate setting problem needs to be consistent with the baud rate of the PLC.

Of course, hardware problems or computer USB interface problems will also be caused.

Three methods of Siemens PLC serial communication

1, RS485 serial communication

Most of the third-party devices support, Siemens S7 PLC can control serial communication by selecting the free port communication mode. In the simplest case, only send commands (XMT) to send information to third-party devices such as printers or inverters. In any case, it must be programmed by S7 PLC. When the free port mode is selected, the user can control the operation of the communication port by sending an instruction (XMT), a receiving finger (RCV), a transmission interrupt, and receiving an interrupt. Siemens S7200

2, PPI communication

The PPI protocol is the most basic communication method of the S7-200 CPU. It can communicate through its original port (PORT0 or PORT1), which is the default communication method of the S7-200 CPU. PPI is a master-slave protocol communication, and the master-slave station is in a token ring network. The user network can read and write instructions in the CPU, that is, the network read and write instructions are run on the PPI protocol. Therefore, the PPI can only write the program on the main station side, and the network read and write instructions of the slave station have no meaning.

3. MPI communication

MPI communication is a simpler communication method. The MPI network communication rate is 19.2Kbit/s~12Mbit/s. The MPI network supports up to 32 nodes and the maximum communication distance is 50M. The communication distance is long, and the communication distance can also be extended by the repeater, but the repeater also occupies the node. MPI network nodes can usually hang S7-200, human interface, programming devices, and so on.

Siemens PLC S7-200 RS232 wiring method and pin definition?

The communication port on the S7-200 CPU is RS485.
Its pins are defined as follows:
Pin No. Port 0/Port 1
1 chassis grounding
2 logically
3 RS–485 signal B
4 RTS (TTL)
5 logically
6 +5 V, 100Ω series resistor
7 +24V
8 RS–485 signal A
9 10-bit protocol selection (input)
Connector housing chassis ground
The S7-200 can support various types of communication networks. Make a network selection in the “Set PG/PC Interface” properties dialog. A selected network will be used as an interface. The various interfaces that can access these communication networks include:
Multi-master PPI cable
CP communication card
Ethernet communication card
The following steps allow you to select the communication interface for STEP 7–Micro/WIN. See Figure 7-1.
1. Double-click the icon in the Communication Settings window.
2. Select the interface parameters for STEP 7–Micro/WIN.
