How do you know the program is protected? if connecting with a hand held programmer, to get past the password question, push "clear, monitor, clear"

Morning all, Anyone know if NTST4.8 will work with an OLD touch screen NTH25-ST121 Seems as if selecting NT31 may allow it to upload a program from a HMI?  

Only NT20S's I have running are with C200H Alpha's. The comms in the Alpha are 38400,   1,7,1,E    NT Link 1:1 The NT20S is set to 38400. I would think the NT20S would communicate with the serial connection, maybe?? If communication is obtained, you will not have access to the "W" memory area. Hope this helps.

What model PLC's are you using?

The same will happen if the Plc and pc don't match, or if the Plc is in program.Hope this helps.

Does the program in the Plc match the program in the pc?

One of our moderators, PMCR, helped me with this. Hope it helps Float scaling.cxp

Good luck with keeping all the crazy Omron guys in line!

I have used 2gb. Though I just picked up some 64mb on E-Bay.

I assume you have tryed to find a copy of the applicattion.... The NT631C is very robust, I have had several running for a long time. A blank screen can happen if both back light bulbs have burned out. If the unit was set up to always be back lite...... Connect your com cable to the "other" port that is free, (the PLC ic connected to one of the comm ports) Work through the software until you have selected upload the application, and you are at the "OK" button, don't hit it yet... As posted by Jay in the maual above, the "secret" method of getting the unit into Maint mode is to hit any 2 non programed corners at the same time. Once in maint mode it will look like this (if you could see it): The center of the Transmit Mode button is 4-3/8" down from the very outside edge of the NT631C Push in this area The screen will now look like this: The center of the Tool transmit button is 4-1/4" down. Push in this area. Now push the OK button on you PC, the application should upload. When the upload is done, the screen will look like this: Push the "Quit" button in the upper right hand corner, the screen will resume communication with the PLC. Hope this helps.

Syswin would be friendlier software to use. A web search should find a place to down load. LSS is very old. Try this Tech note provided by Jay: http://forums.mrplc....ads&showfile=71

I agree with MPM, unit will run all day connected to the peripheral port. The units weakness is the NT2ST software, it's buggy. The front and back of the case comes unglued if tightened slightly too tight.

Make sure you get the entire part number for C200H rack mount LK201 or CPU mount LK201. Once you select the type, try finding one on E-Bay: http://business.shop.ebay.com/i.html?_nkw=omron+lk201&_sacat=12576&_odkw=omron&_osacat=12576&_trksid=p3286.c0.m270.l1313

Which PLC

Welcome to the forum The C200H does not use RS232

"BlueByu, do you still have any of these left?" All are now gone.

Page 290 of the manual W394-E1-12+CS-CJ-NSJ Series+ProgrManual @ MrPLC.com

Try pushing the F1 and F6 keys before power up, and continue holding them until after power up, as suggested in post #3 of: http://forums.mrplc....showtopic=13225

Good evening Jay, Sorry to correct the master, the OP is dealing with a non touch screen.

Is the unit connected to a PLC that is powered up? What cable are you using? Do you have the programming software? He is a guide http://forums.mrplc.com/index.php?app=downloads&showfile=501 Hope this helps

Try changing the reset bit to 200.05

Trying to duplicate your problem: Using the following: CS1G-CPU43 NT631C-ST141-EV2 Version 3.13 and also on a NT21-ST121-E V1.03 NTST Support Tool V4.7 Communicating with the PLC on port B, NT Link 1:N, high speed I can write from the PLC to the either NT using DM32700. The NT631C and the NT21 displays the value correctly. Hope this helps

Hope the CPM2C is the same as what Jay posted in this thread http://forums.mrplc.com/index.php?showtopi...ral+port+wiring

Welcome to the forum. I am not aware of one document that covers what you ask. Each manual has a list of all instructions in the appendix, it is very concise very compact, limited description. As C200 is not concise enough, ie; is it a C200H, or a C200HX? they have similar, yet different instruction sets, I think the manual is the best bet. Generally speaking the newer processor contains the most instructions, including virtually all instructions the oldest contains. If you are trying to pick a PLC to use for learning or teaching, pick the CJ1, it's the newest in your list. Hope this helps

Thanks for posting what you found, it will help one of us down the road.
