Hi j, According to the last Operating System Compatibility Matrix that I have (Apr-2012) RSLogix 500 v7.1 is not listed under Windows 7, which means to me that v7.1 is not guaranteed nor supported under Win7 and surely not under newer Operating Systems. (This doesn't mean it won't work but it is definitely not supported) Another issue you should be concerned about is that most new laptops lack of serial (RS232) comm port and according to my experience the majority of USB to Serial converters are not reliable. I would personally consider buying an ExpressCard Adapter. Hope this helps.

Saludos paisano, Temperature regulation is usually a slow process. There is something called time-proportional control which is most probably what has been implemented on the other machines. RSLogix 5000 has an instruction you can utilize: SRPT The samples folder in your RSLogix installation contains a complete temperature control example. Take a look at it. Bye

Hi, Wonder why I cannot paste when I'm writing something in this forum. I like writing my replies in msword, have my spell checked and then copy and paste but the system doesn't allow me to do it, is there any good reason for this? Just curious Bye

Solved!!! Using Chrome instead of IE Happy now

Thanks for answering. Please don't take it the wrong way but in this case my offer will be to collaborate with you from the forum for free. Can you post your circuit diagram? (A handwritten sketch will do) Can you post what you have programmed so far?

Hi Worx10r, I think it is advisable to include a HMI in your machine to allow you to re-adjust times or events for the automatic cycle and also to show the machine condition in case the auto cycle is interrupted due to a malfunction. You can utilize a small PanelView component for this. I would like to know what this means exactly Good luck! Bye

Hi, I have personally used only controller scoped tags so far but I know there is a programming methodology called modular programming that only uses program scoped tags which allows the programmer to copy and paste "modules" without causing tag naming conflicts. When you use program scoped tags you can have tags with the same name in different programs. In case you feel curious, download ia-rm001_-en-p.pdf and ia-rm002_-en-p.pdf I think phase programming is an implementation of modular programing as well Bye

Hi karkas44, I recommend you to download the MicroLogix Programmable Controllers Selection Guide 1761-sg001_-en-p.pdf and the CompactLogix System Selection Guide 1769-sg001_-en-p.pdf These are quite different plc families and differ a lot in capabilities, price and programming software. If you want more specific advise you have to provide more detailed information like what kind of DI (AC or 24VDC, high speed or regular), what kind of DO (Relay or 24VDC), Analog (Voltage or Current, Isolated or Non-isolated, acceptable resolution), Control (On-Off like a Thermostat or Time Proportional), PID (simple or advanced) Bye

Thank you guys, I am going to offer my client a CompactLogix solution. Bye

Hello, I've been asked to migrate an application from a Siemens S5 to an AB plc. The hardware is not demanding: 6 x 8DI (24Vdc), 4 x 8DO(24Vdc) and no HMI. Although I am not a Siemens expert I have the capacity and the tools to upload the program, analyze it and write an AB working copy of it. I would like to know your opinions about the convenience of using a CompactLogix, a SLC500 or a Micrologix. I am not considering a CLX for cost reasons and the application does not justify the use of such a powerful plc. For me CompactLogix would be the way to go but I've been doing several micrologix projects for that client and now he has a considerable base of mlx 1100, 1200 and 1400 installed in his factory, besides he also likes the idea of using the same programming software for all his plcs. SLC500 would be the natural replacement for the S5 I guess, but I am afraid it will shortly find the same end as the S5 and AB terminate the manufacturing of it. A Micrologix could do it, it's just that I would like to use a plc with no embedded I/O on the cpu (just a preference, not a strong reason). Thank you

Hi Ken, I thank you for your prompt reply and help. I really appreciate it. Honestly I don't follow college football from here. What I can say is that I enjoyed my those times in Michigan very very much. Many good memories. I remember that by that time (back in 1988) the head coach was Bo Schembechler who retired not much later. I also remember myself going to watch some Detroit Tigers games at the extinct Tiger Stadium, I remember Sparky, Tanana, Trammell and Whitaker (Louuu), Evans, Lemon, Sheridan, Pettis, Lynn, Murphy and of course our Luis Salazar. I became a Tiger's fan since then and I still am. Thanks again, bye

Hi This is most probably an easy question. It's just that I want to be prepared. A client of mine is buying a new Panel View Plus 6 to which I have to download an application I created with Factory Talk View Studio 6.10. The thing is that the new Panel will probably come with a firmware higher than 6.10 and I do not count on a higher version of FTV Studio. Will I have to downgrade the PV? Is that possible? Will the PV run my application even if it is a different version? Will I have to buy a more recent version of FTV Studio? Thank you

Hi, I would specify the fuse or fuses according to the DCS outputs capacity since that is what should be protected Bye

Hi, Not an expert on this but as far as I know the 252 (11111100) on the mask should let you communicate with any device with a 0, 1, 2 or 3 in the same subnet. I suggest: 1. Check the network topology. Maybe your computer and the slc are not in the same subnet and the issue is a gateway configuration problem. 2. Try resetting the subnet mask to 0.0.0.0 and setting it up again. Make sure BOOTP be disable. Here is a link to a quick start guide for ethernet slc processors that might be of help http://literature.rockwellautomation.com/idc/groups/literature/documents/qs/1747-qs001_-en-p.pdf And please, let us know when you solve the problem Bye

Hello, First of all, I hope my English be understandable enough. I have attached a hand drawing of the circuit that I utilize, it's really simple. In this case you don't need any extra components since they are already inside the sensor. In case you are curious about the components in your drawing (the one you posted): one is a NPN transistor, the resistor is needed to limit the current fed into the transistor base and the diode is used to protect the transistor against the stress produced by the relay coil when the current flow is abruptly cut. Bye

Could you post the diagram? I'm pretty sure many of us will be able to tell if the circuit will work and what the resistors and diodes are for.

RTO Preset is a DINT-type operand (see: 1756-rm003_-en-p.pdf). You should have no problem,

Hi all, I've been asked to upgrade the firmware to a couple of compactlogix plc's from v17.2 to v20.12 for normalization reasons. So far I have only flashed new ones. I would like to know if I have to empty the plc's memories before flashing and what would happen if I don't. I already upgraded the programs from v17 to v20 in my computer and they are ready for download. Thank you.

Thank you very much. I should have written "clear" instead of "empty". I sincerely apologize for my english (or lack of it). Thanks again

Hi, I am new to Siemens PLC's. I have STEP7 version 5.5 installed in my computer. Just want to know what happen if I also install STEP7 V12 (TIA). Can I still edit and download V5.5 programs? Can I have the two versions installed? Thanks

MS Windows XP and it works well. I saw a compatibility tool somewhere in Siemens' website I plan to install the trial version of STEP 7 V12 on the same machine but haven't got it yet bye

Thank you!

Not sure but if you are talking about a 2711-K14C1 it has one Remote I/O port, one Ethernet port and one Printer RS232 port and as far as I know you cannot use the printer port to extract the program. I didn´t know the PV1200 existed

Suggestions: 1.- Try using the "Ethernet devices" driver (not the EtherNet/IP Driver) 2.- Make sure you have the corresponding EDS for the ML1100 3.- Check if it is a RSLinx Classic version issue Bye
