Hi all users! We respect your opinions. We know some of us see the poll but do not play the poll. Please, all viewers, play the poll because the end of this section is near to the end. We need the rate seriously. Thanks a lot.

Hi GURUs! I have a plan to install a new system at the old plant using A series PLC from Mitsi . The original plant has many of level transmitter for level-viewing purpose. The transmitters use 20mA standard. Now, I intend to use AD converter modules (A1S64AD) with A2SHCPU. ****Can I configure the modules in my ladder program? If it is possible, please give me an example.**** Thanks all.

Hi Gentlemen! Please don't cry out loud. "TheLearningPit" is a good site for newbies. If you have downloaded the free simulator from this link PSIM, watch and give comments to my attempts. Thanks. Sim_pro.zip

Hi Buckaroo! I think I should help you. I have some docs and softs for S7 family programming. 'Cause they are the part of STEP 7 programming software, should I attach the manuals in this forum?. If someone recommand to post them here I will follow it. Please be patient.

Be careful markn! Sometimes, the "Flash" will destroy your PC. Make sure you actually need to upgrade the BIOS. Please think about others who can use the softs on the old PCs. With best wishes

Please read this topic for cable. Simple programming Cable by "Sergei Troizky" It is a wonderful solution and it is really useful. The following link will help to have the soft. www.chinakong.com/.............

Thanks a lot PdL! I don't know how to open a poll, previously. Your suggestion will fit to me. PS., Sometimes I'm affraid to mess up the forums. I worried my posts would disturb to others. Anyway, lets start a poll.

Pardon me Sir. I'm really sorry for the conversations. I won't make any other mistakes anymore. Lets talk about more insteresting things in the future. Sorry again:-(

Yes, I also agree that it should be limited in sections. But, I can't understand why it should be here the forum named "Computer Help and Networking" than "SCADA and Automation Networking".

Yes, rainofwind You are quietly correct. I also think it isn't hardware problem. But, let's wait his reply.

Hi markn, This FAQ will answer your question about checking the serial port. But I think it is the problem due to your RSLinx version. 'Cause I had met the problem before. Some of RSLinx version can't be configured in a virtual machine like "VPC for Windows", and they can't communicate with "USB to RS232" virtual serial port and bla bla bla bla ............. My final solution was reinstallation of WIN98 on another primary partition of HDD and reinstallation of RSLinx and RSLogix as well. ""Don't forget to backup your activation keys"" Cheer to manufacturers!

Hi MEK, The attachment will help you. If it isn't OK yet, I can support you with schematic diagram of my own adapter (DIY version) and connector pin-out. SNPSerial.pdf

Wow! Can't anyone help to open the new forum? Attention to Readers: Please leave a comment here if you are interested in this topic. Thanks!

Hi, You cannot copy the program, status chart, symbol table, or data block in its entirity. However, you can select individual networks, instructions, or rows and copy them one piece at a time. There are two ways to copy material from one project to another. Using Two Instances of STEP 7-Micro/WIN 32 1. Open two separate instances of STEP 7-Micro/WIN 32. (Double-click on the STEP 7-Micro/WIN 32 icon or choose Simatic>STEP 7-Micro/WIN 32 from the Start menu. Repeat.) 2. In the first instance of STEP 7-Micro/WIN 32, use File>Open to open the project from which you wish to copy. 3. Select the material and use CTRL + C or Edit>Copy to copy it. 4. In the second instance of STEP 7-Micro/WIN 32, use File>Open to open the project into which you wish to paste the material. 5. Place the cursor at the appropriate location and use CTRL + V or Edit>Paste to paste the material. Note: Remember to save your work in this project before closing it. Using a Single Instance of STEP 7-Micro/WIN 32 1. Use File>Open to open the first project, the one from which you wish to copy. 2. Select the material and use CTRL + C or Edit>Copy to copy it. 3. Use File>Close to close the first project. 4. Use File>Open to open the second project, the one into which you wish to paste the material. 5. Place the cursor at the appropriate location and use CTRL + V or Edit>Paste to paste the material. Note: Remember to save your work in this project before closing it.

Hi! It isn't zener. It's more likely to be varistor or surge-supressor. I think those devices are parts of RS232-RS485 interface converter. You should spread the area of "bmp window" so that the others can see and suggest more conveniently. Please be patient to edit your pict.

Hi, Please be patient. I am trying to program a sample code using CX programmer V5.0. I have decided to post it here using PDF format.

Ans: 1)S7-200 family needs MICROWIN or MICRODOS softwares. Any versions of STEP7 can only handle the S7-300 and S7-400 systems. The family named LOGO uses the LOGOSOFT. 2)Wizards help us with default settings and default options. The ones who don't know much about the MENU/COMMANDS of the software can use wizard to set up a new project. 3)Some have merrit, some have demerrit. 4)Yes, you can but choose wisely. 5)Yes, use speciality modules if needed. 6)Based on program. 7)I'm not sure. But, do you hate wizards?

Hi, Please let me know what you really want. I think I can help you.

Sure, you can. Use an internal clock timer and a control relay and/or jump subroutine in function block. If I know your PLC model, I can explain in detail. Good luck

Hi, You can purchase the (100-3101) Standard programmer for TI 100. http://www.tirepair.com/ But have you tried to backup EEPROM with a universal EPROMER and open it with window based software? I have tried once and successfully managed the original program (although can't monitor the PLC operation).

Hi, In Citect example, it can't be. The example uses the Ram Disk PLC and/or Hard Disk PLC. Those PLCs are simulation PLCs and Dxxx are only the bits in them. With real PLC, the variable tags you want to generate depend on the type of PLC selected.

Attention: To All Once I had an interface converter (1747-PIC) for Allen-Bradley SLC5/01 PLC. But it was broken due to my students' fault. I can't fix it till now. I have decided to replace it with an easy-2-use RS485 converter. There is a problem with "EN" signal for transmission (PIN 5 of RJ45 connector at SLC side). I think it is driven by RTS signal from RSLinx. Please kindly let me know the solutions as Best regards AnO anoase@myanmar.com.mm
