Dear friend, try to check for APT on Siemens web site. Have a look to this link: "http://support.automation.siemens.com/WW/llisapi.dll?query%20=sinaut&func=cslib.cssearch&content=skm%2Fmain.asp〈=en&am%20p;siteid=cseus&objaction=cssearch&searchinprim=&nodeid99=" with respect, dekor.

Dear friend, for TI 505 you sould use APT (Automation Programing Tool) From my experience, is working in XP Prof. also. Try a search on web... With respect, dekor

Dear friend, the reason of forums:

Dear friend, the component is LM7805, or equivalent .It is a compact IC 5v DC voltage regulator integrated circuit. All the best. dekor

Dear friend, I am not the author of the PCB that you see. For your situation you can use as I said before the Ethernet converter. It will create the RS232 port over the network. Is like your computer is on the office and he have the COM port on the plant (800 m away). I had tested also products from different manufacturer, but without good results. dekor.

Dear friend, I am happy to hear you have succeeded to build your TTY converter. For which reason you need to connect the PLC to computer at long distance? How long is the distance? Do you want to receive data from PLC, or you want to debug program with Step5 ? If you use a windows based program (like S5-S7 for windows, or PG-2000) you can use an Ethernet-RS232 + TTY adapter. You will get a very small delay, but you can be even in other country..... I have good results with MOXA converter model: DE311. All the best, dekor. NPort_DE_211_311.pdf

Hi, usually Siemens provide a CABLE , and this cable is used in conjunction with special laptop. This laptop had inside the converter. Have you tested the converter with same laptop that work? It was the same PLC? Was the same conditions? Can you show us some detailed pictures of your converter? PS.: also I use an USB RS232 converter for S5, but not with Step5 programing software. Check on the web for other windows based soft to program S5 PLC. dekor

Dear friend, The CABLE from Siemens that you have use was connected to a Siemens PC (programing console) ? The above diagram is for "active". Sorry but this is not a "passive" converter. The active converter is used for a standard PC with serial port to communicate with S5 PLC. Is that your situation? With respect, dekor

Dear friend, usually I use the MAX232 and CNY17. It works fine. Just I had build 2 converters last week. Both of them are good. Please verify one more time the way how you have build the PCB, positions of parts... connections on the plug.... Can you send some pictures with your converter? What software you use for S5? Is that soft working OK under XP environment ? Maybe VISTA ??? On XP, I use different software to program S5 devices... Step 5 is not working easy under XP. With respect, dekor

Hi, if you want your PLC restart automatically at power ON, you have to select the RUN position of switch. Otherwise if you select TERM position, the PLC must receive RUN command from programing PC or PG. dekor

Can you post the PLC program? dekor

Check simply things like: On start-up (at power up) of OP press ESC and arrow up and keep them together pressed for few seconds. Usually many Siemens OP are going in transfer mode. dekor

Hi, maybe is better to post the S5 program on forum. dekor.

Dear dsc, please read the previous post and you will find a solution . Also is for free. dekor

Hi Gawie, I want to propose you this small program. analog_average.rar Also you may check for mean the next link. www.nubitek.com There is a free library about what you need. P.S.: I hope this will not be considered as advertising. dekor

Hi, check for this. dekor.NONAMEZ0.SEQ.pdf

Hi, Can you upload the program ? I have received once a warm about this subject.... If you can upload, send me the project, and I will help you. If the PLC is password protected..... Any way, all the best !!! dekor.

Hi, you must add on the network 3 a positive edge transition in series with VB3 (in the PDF example from above). About the real time clock: is not supported by all the S7-200 PLC. Check before. dekor.

Hi, please read the next document and you will get the necessary instructions inside. nubitek_free_utils_manual_v1.0_en.pdf Please, not to be considered as advertising. dekor

Hi, mr_electrician I want suggest you some simple things that can help you. Go in: system blocks \ input filters\ and change the default values (6.4ms) to minimum (0.20ms). Normally this would be enough. If is still not, try to use "catch pulse bits" option and select the inputs that you consider are necessary. If is still not, try to decrease the "background time" to 5%. " You can configure the percentage of the scan cycle time that will be dedicated to processing the communication requests associated with a RUN mode edit compilation or execution status. As you increase the percentage of time that is dedicated to processing communication requests, you are increasing scan time, which makes your control process run more slowly. The default percentage of the scan time dedicated to processing communication requests is set to 10%. This setting was chosen to provide a reasonable compromise for processing compilation/ status operations while minimizing the impact to your control process. You can adjust this value by 5% increments up to a maximum of 50%. " (SIEMENS HELP TEXT) dekor

Dear friend, first of all (if I understood well) you want to change actually RAM memory with EPROM memory. Think twice. Assuming is accepted by this type of CPU, you have to look after DB's in program. If the DB is on the EPROM cannot be changed by the program and the CPU go in STOP . dekor.

Hi scientific, I think you use USB-RS232 converter + RS232-TTY to connect your laptop to PLC. I do in the same way. The main problem is coming from USB converter and drivers. After long searches I have buy one from FTDI company. The converter is OK. The drivers not so good. Also is a problem when you use XP: you must be ADMINISTRATOR. Finally I had change the programing software. New I use PG2000. Maybe is a good option for you.

Dear friends, Please help me to solve next problem: I have two identical machines which use IMC-S class. For one of them it was necessary to replace the IMC. On the new IMC was no program inside. I want to copy the program from the IMC of the good machine into the IMC which has been replaced. When I try to upload I receive an error message" Fail to stop program". Then I try to stop the program using the stop button from the GML commander. I receive the same message. I use the GML commander vers. 4 and the firmware of the IMC is 303003.9A Dear friends, please guide me to copy the program from one IMC to other. dekor.

Dear Paul, first off all, thank you for response. I am not very familiar with this kind of controller, and my questions may look strange. My controller have a 485 connection and also Remote I/O. Do you suggest to disconnect both of them and then to try to stop the controller? If this fail, the kill command will not affect the program inside the controller( excepting the stop of execution) ? Assuming this, for hard reset I must press the reset button on the controller (below the red LED's ) ? After hard reset it is necessary other precautions, like upload the program (or script) or something else? dekor.

Dear ramaslabas, try to make yourself an very good converter which i use for years. Drawings, PCB and layouts in this post http://forums.mrplc.com/index.php?showtopic=10049 I wish you good luck.java script:emoticon('', 'smid_5') dekor.
