Omron PLC Center

Setting up communication between the Touch Screen (NS-Series) with Omron PLC.

Communication settings in the PLC.

Steps to set up communication with the PLC is the following step.
New Project to create a new menu by going to “File> New” window will appear “Chang PLC” in the Figure 1.

Figure 1 window Change PLC.

From Figure 1, select the PLC Haiti in the “Device Type” to match the PLC that the user actually uses. . In this author to choose a model CQM1H-CPU21. The setting “Network Type” is based on interface cable between the computer and communication. port of the PLC. that if interface cable to Port RS-232C (DB9 PIN) on the the CPU, select “Network Type” to “SYSMAC WAY” but if the interface cable to the “Peripheral Port”, select “Network. Type “a” Tool Bus “. When it has finished setting the selected Click” OK “.

After New Project to Interface computer and the PLC to the PLC by accessing the menu and select “Work Online” Figure 2.

Figure 2 interface CX-Programmer. With the PLC (Work Online).

When the Interface. “CX-Programmer” to the PLC can then change the operation mode of the PLC to the “Program” menu, select the “PLC> Operation Mode> Program” Figure 3.

Figure 3 Change of operation mode of the PLC.

Then open the “PLC Setting go to the menu PLC> Edit> Setting window displays” PLC Setting “window up” PLC Setting “Click to select the tab” Host Link Port “Figure 4.

Figure 4 for PLC PLC Setting windows version CQM1H-CPU21.

The mode settings for communication with PLC Touch Screen is a multi-mode with the following.

Host Link: a mode of communication is a two-speed is the speed to 19200 bps 9600bps and can interfaceTouch Screen is the only one to 1 PLC.
NT Link (or NT Link 1:1): The speed of transmission is the ability to .115200 bps interface Touch Screen is the only one to 1 PLC.
NT Link 1: N: a mode of communication speed to a second speed is 11520 bps and 38400bps interfaceTouch Screen can be 8 characters to 1 PLC.

CQM1H which will be available for Host Link only to the NT Link, but for the new PLC is like CS1/CJ1 the Host Link mode, select the NT Link 1: N. For authors themselves will select the Host Link mode since the. Write a the PLC is CQM1H the “Communication Setting” the author will select Baud Rate to 19200 and in the Format must be selected as 1, 7, 2, E only (because of the the Touch Screen is set fixed already. at 1, 7, 2, E) Figure 5.

Figure 5 Setting mode of communication. And speed of data transmission with Touch Screen for PLC model CQM1H.

When the setup has finished, go to menu “Option” window “PLC Setting” and select “Transfer to PLC”. Because while there is no Transfer Transfer window shows the situation will only notice the image mounted hourglass

To confirm that the Transfer complete Somboon can check it by accessing the menu “Option” and select “Verify”. If the Transfer complete Somboon to the window, as Figure 6, but if the Transfer does not equation Map. True to the window ณ์ Figure 7.

Figure 6 “Verify” finished Somboon Figure 7 “Verify” is not Somboon.

Verify completed on Somboon then. Stop the interface between the PLC and Computer in the menu “PLC> Work Online”., And then close the supply of the PLC and set the Dip SW pin 5 to OFF position and open new . Because values. Set via PLC Setting window will be closed when the supply of the PLC and then reopen

Setting the Communication Screen Touch Screen.

CX-Designer to open up and create “New Project” menu by going to File New Project window appears, then “New Project” Figure 8.

Figure 8 window “New Project” for the screen, Touch Screen.

Then, select “Model” and “System Version” to match the version required by the user that this author would choose a model NS5-SQ0-V2. The “System Version” is Version 8.
Click the button and then select “Comm. Setting” window will appear “Comm. Setting” in the Figure 9.

Figure 9 window, “Comm. Setting”.

Click and then select “1: SERIALA” window will be shown at 10.

Figure 10 Click on the window, select “1: SERIALA”.

Direct Serial Port box, set the “PLC” the “TYPE”, select the SYSMAC-PLC.

The importance of this window is the box Protocol and Comm Speed mainly is to set “Protocol” to match the “Mode” and set “Comm. Speed” to match the Baud Rate window, “PLC Setting” to configure. earlier. In which the author will need to set the Host Link protocol and Comm. Speed is 19200 Figure 11.

Figure 11 Configuring the Host Link Protocol and “Comm Speed” to 19200.

Once set up, then Click the button “OK”.

After that, it will Transfer Setting the value to the Touch Screen menu, go to the “PT> Transfer> Setting”.

Then, Interface cable between PLC and screen Touch Screen. In the part of the Touch Screen interface cable with SERIES A. The interface cable between the PLC and Touch Screen display will be in accordance with Figure 12.

Figure 12 for signal wiring between the Omron PLC Omron Touch Screen.

If Interface Screen Data page will display the first user created on the screen of the Touch Screen. But if the interface is not the message. “Connecting …” in the lower right corner of the screen, Touch Screen.
