I don't know if you have all finished with this thread but I'll add this. Both options are va5lid depending on other measures. You are arguing about the difference between SELV and PELV power supplies. The requirements for SELV are quite demanding in separation vof circuits. PELV poses risks of equipment damage. In ISO60204 I cannot find reference to SELV , only to PELV (possibly supplied by a SELV power supply). So does everyone using SELV used strict seperation of "high" voltage and control wiring? Everyone who doesn't is connecting one leg of the supply output to ground? Good, we can all be friends again. But please comments are welcome / abuse accepted. (The 60204 standard and use of SELV is the part I need to clarify.) Apologies if this has lots of typos. I'm on my phone as my antivirus is blocking this site.

Any way to use a SCO9 and a homade cable? Any tips appreciated.

Thanks. I can live with that.

Well spotted. It is a F1. Medoc only?

To add to that: 1.Brake voltage will be on the nameplate. SEW brakes are as likely to be AC as 24 vdc (400/230) 2. This is a squirrel cage induction motor? The brakes usually have a manual override lever. M10 bolt in the slot in the cowl works. Do not try this on the machine unless safe to do so.

We have a TP270 with a failing screen (vertical lines). If I can locate a replacement will I be able to update the new one with PROSAVE? Are there any "Gotchas" Would a hardware repair be possible / could the screen items be changed? Anyone have any experience or recommendations? Thanks.

Thanks again. Do you do much Siemens HMI work? Conversion of program to newer HMIs or repairs? The cost for replacements for these units which are near "end of life" is horrendous.

GX configurator DP used to be the required software. Edit : I just tried to create a project in Navigator / GX works and it says I need to upgrade to use the profibus unit. I don't think this is true, maybe a translation error, but I'll update and try again. Edit 2: Yep, I'm on the latest version.

OK, thanks, I've done it with the older units OP17 I think but I never seem to get the same job twice.

Great! Will do. Thanks.

What is the easiest way to set a GOT2000 clock? I need to change for British Summer Time. Automatic wou and be good but operator setting is acceptable.

Hello All, I'm looking for standalone web browser in a HMI style form factor. Ideally with a touchscreen. A web server would be good too. It would be to give access to automation devices with an integrated web server. Panel mounted preferred. Can anyone suggests anything?

Thanks Bryll.

Google has turned up a nice looking Phoenix Connect web panel. My proof of concept is a small development SoC (Rasp Pi) with a Firefox kiosk.

comprop.bmp Could be anything. See attached for the first thing to check.

Thanks. I tried it and it works. Power has to be cycled after a change.

I need to connect a FX3GE to a E1000 HMI. I can't find a how to for this connection. What driver do I use in the E1000? What setting in the FX3GE? I am assuming I use the FX3U ethernet driver in the E1000? UDP, MC protocol, 5001 host port, IP address of E1000, 5029 destination, setting at the FX end? Can anyone confirm these settings?

Are all the steps in the same block? ---[RST BL0]

Hello Flippyr. Does the machine currently work? The run light seems to be off/ battery and fault light on? Forget about the existing program. Start with the electrical schematic. Re-create it if you do not have it. Now thing about how you want the machine to work. See if this matches up with the existing hardware. From the earlier photos it looks like the PLC only has one input connected and there are two (single phase?) motor contactors and a few other outputs. So I'd say you need to start at the hardware and work back to the software. Above all - be safe. Where are you based - PM if you need to.

What is the program extention? Is it *.dat? If not can you get them to supply the "Project Transfer" file which will be a *.dat file? Load this on to a USB stick, plug it into your HMI, accept update, job done. Assuming you have access to a USB memory stick. Edit: It looks like your software and program are for the PLC not the HMI. See page 24.... http://web.ist.utl.pt/ist11390/AI/SAIA%20PCD3%20Series.pdf You need to plug it into the PLC USB port not the HMI port.

Peripherals -> right click -> properties. Help I found this: Error code The driver received an error code from the controller. For more information about the error code see the manual for the controller.

The attached drawing shows two ways to connect two contactors to a safety relay. Assume feedback loops and reset circuits. Is there a reason why one would not be acceptable as Cat. 3 architecture? Can anyone comment on the merits of each?

I was originally thinking about Cat 3 and not cat 3 rather than 3 vs 4. I read some of the recommendations on daisy chaining and try to avoid it now more from a desire to avoid documentation and dubious assumptions than thinking it unsafe.

I saw that AB page when I was wondering about this. It used to be the norm to show one output contactor connected to "0v rail" after the safety contacts and the other to the "+ve rail" before the safety contacts. Sort of one sink and one source. Not seen that in a while. Pulse testing is an input thing. Each input channel has a different pulse sequence so that shorts or wiring errors are caught. I think both are Cat.3 but they have different fault exclusion requirements. It's difficult to talk in the abstract about safety now as it is about the components used and avoiding common cause failures as much as the way it looks on the wiring diagram. Maybe safety needs a new forum category?
