Hi, I have the following PLC: CP1L-M30DT1-D It has 2 pulse outputs that are built in (100.00 and 100.01). This is currently not working. I'm checking with an Oscilloscope. I verified the O-scope's settings and checked a single output . . . O-scope is OK. I used the settings (with values changed a little) in the Help example. Here's what I am using: . . . . by the way, is PLS (not PLS2) better? PLS2 #0000 D100 D111 Registries are: D100: #0002 D101: #0002 D102: #0003 D103: #0000 D104: #000F D105: #0001 D110: #0001 D111: #0000

I recently did a barcode scan project with a CP1L into the serial port successfully using a home-made C200HS-CN220-EU (got an Omron cable guide from tech support) , but I am having no luck trying this on a CPM2A with the same cable. I also tried a - CN229-EU. I'm probably missing something obvious, but I am beating my head against the wall trying to get this to work. I used the same program from the working program on the CP1L except I changed the addressing format and PLC type to CMP2A. Settings are RS232, baud, etc. are matching, and I'm using 256 received bits. With the CPM2A, what ALL settings should be set to allow (for example) a barcode scanner at 9600 7 1 even (with 256 bytes recieved data set, and CTS disabled)? I'm doing this on the DB9 Host link port on the PLC. Besides the 'Settings' section of the PLC, is there another place that the settings need to be input?? I don't mean to be negative, but I'm little disappointed in the lack of straight-foreword information about this. I called tech support a while back on this and got several different answers with different individuals. I would be surprised (pleasantly surprised) if someone could help me resolve this. Thanks, Ben

Hi, I'm choosing a SCADA system to do the following: Control a central PLC from an offsite via Web-based HMI. I would like to use FX or FG Mitsubishi with ethernet add-on OR Omron CP1H with ethernet add-on OR other?? Although I will ultimately be doing this for work (unfamiliar territory for me) with Mitsubishi Q and MC Worx, the application I have in mind is for a Smart-home project / security project I'm doing myself. So, a few things I'd like to do: -Control and view Data registry DM, D in the PLC over a Web-based HMI from offsite location. Control, not just monitor -Also, have local HMI capability PC-based (I think I'm OK on this one- could use GOT or NV designer, etc. -As a last set of 'bells and whistles' , I'd like to view camera feed (security camera) on the Web-based HMI. -Audio?? if possible?? I'm researching the MC Worx and getting prices since I will eventually need to for work, but I'm curious what other brands (Omron, Eaton, or AB) have to offer. I'd really appreciate feedback. I'm really excited about this one.

Can anyone share their experiences with Omron V680 RFID part-tracking system? The decision has been made to instal that system on one of our conveyor lines. (tags on pallets, etc.) Thanks

I will soon be using the V680 RFID controller (interface with Omron PLC, etc.). Has anyone found any programming examples, documentation, etc? We are using pallets on conveyors and tags (standard circulating conveyor setup) I have a little experience with SUNX and IFM Rfid systems. Any help or experiences shared would be greatly appreciated. I am trying to prepare for a HUGE conveyor project. Thanks

I am working on a complete re-write of a machine at work. There is currently a CPM1 Micro PLC in the machine. It was programmed in CX Programmer 3.1 (or lower). It looks to be well-over 10 years old. I, however, have CX-Programmer Lite v. 9.11. Due to limited access to this machine at work (24/7 line running), I made a test setup with lamps and buttons at home (I have a CP1L newer model at home) I have been having to print out the code at my house and write it in at work. Is there an easier way?? Also, I have a touch-panel display NV3Q-SW21. (it is just coming out of the COM port of my CP1L at home. Will this interface with the older model CPM1. Sorry I don't have more specifics. Ben

Hi, I am using CX Programmer 3.1 for a project with a CPM1 brick PLC. I got a compile error as I selected a bit 220.00 to a differentiated bit (text became red, etc.). Is this a version issue or my lack of knowledge of the programming style? I'm accustomed to AB OSR command. . . .that's what I'm looking for. thanks

I have a few years AB experience. My opininon is that is is extremely easy to program (graphically, easy to make rungs, navigate, etc.). I have even less Mitsubishi experience: but from the work I did GX developer, it seemed a bit archaic, hard to program, write rungs, etc. I just started with Omron. I haven't done enough to form an inteligent opinion. But it seems easier to program than Mitsubishi. I want to start my own business one day. I'd like to build small workcells and simple semi-automaitic equipment, quality inspection station with camera's, etc. I have zero experience with Seimens. I don't even know that I spelled it correctly :) I'd like to be versitile in my career with PLC's, but I'm afraid of the cost and time I need to invest in Seimens PLC and software. Can somone comment on that?? I love this stuff (PLC programming). . . . I just want to make sure I'm headed in the right direction as it relates to market demand. I purchased CX one light recently in an attempt to learn Omron PLC programming. I also purchased a CP1L and a servo system with and NV HMI. I'm slowly learning it. I have TONS of things I want to learn how to do: Interface with Mcrsft. Excel (DDE or OLE) write to Excell from DM registry and read FROM Excel TO DM registry, etc. . . . Ethernet communication, etc. . . I'm excited. . . . but again, I want to make sure I'm in-line with the market demand by making Omron my main PLC programming concentration. I would appreciate any advice/ comments. thanks

In the case that anyone has any thoughts or different ways of doing this, the following are some of my projects . . . . I'd be glad to share details to anyone doing similar projects- maybe we can learn together! [not asking questions here . . . just sharing, thanks] First Project: I am making a key entry program. (yes. . . this is re-inventing the wheel, but by doing this, I have full control of my key entry). I have wired each of the 10 digits to PLC inputs. I am making a security alarm code for dis-arming. each key stroke adds an instance in a counter. The counter then is in AND relationship with an Integer registry that contains the digit value that I moved into it in an earlier rung. Another project: using an LAP Omron servo with CX programmer to make a CNC mill Ben

Hi, I am trying to learn CX programmer. My background is Allen Bradley. I have 3 sets of questions: 1.What is the difference in Auxilliary bits, Working bits, and CIO bits? 2.Can I move an integer into a location N10:3 (AB reference) and later parse out each the 16 bits? [in other words, create a status word that has no decimal significance, just place holders for status bits] 2. Is there documentation that describes how to communicate between Mcrsft Excel and data registries (to and from) Thanks, Ben

Hello, Sorry to ask a basic thing . . . but I have to 'dance' around a tight production schedule, so I can't afford to 'play' with it till I get it right: Questions: What steps do I need to take to get online and upload a program while the machine is running? [i have the following below:] [i'm familiar with AB Micrologix, but new to Omron] I have: Omron CPM1 Micro PLC, CX-One v 3, CQM1-C1F02 cable, (also an optional USB-C1F02). I did the following already: 1.Opened CX-One (no file opened, just the software) 2.With the USB-C1F02 plugged into the PC and peripheral, I selected AutoOnline from the menue bar 3.I recieved a message that I 'failed' to get online [Note, I have not tried the CQM1-C1F02 cable yet] Am I safe to continue to try to upload without affecting the PLC running operation? Are there any 'no-no's that would screw up the existing machine while it is running? Thanks alot

Hi, I'm new to Omron PLC's (experience with AB and some Mitsubishi, though). I am trying to do a basic thing . . . but I want to run this by the more experienced programmers on this forum to ensure I've got it right: I need to upload a program from a Symac CPM1-10CDR-A. From what I've gathered on the online manuals: Here's what I need to do: 1. connect to the PLC peripheral (via cable CQM1-C1F02) 2. open a blank program in CX-One with the Com settings: Start bit:1/ Data bits:7/ stop bits:2/ parity:even/ baud rate:9600 3. Go online (or Auto online) 4. Keep PLC in Run mode 5. Upload. 6. Save to the laptop for offlline work. Done Can someone verify that this will get the program on my laptop so I can troubleshoot it offline? Also, will this give me the bit comments? Finally, are there any steps I need to take to ensure this does not interfere with the existing PLC? Thank you very much, Rob

I'm trying to introduce automatic torque systems into the plant I'm working at: One of our processes in production assembly is torquing a male threaded fitting into a female fitting at a customer specified torque value(39Nm). We are currently screwing the male fitting into the female fitting by hand as much as possible --15 hand turns (approx.) Then, we use a torque wrench to finish it to spec. The goal for the new system, is to srew the parts together and torque them all in one step. I'm sure there is something on the market already, but . . .what I'd like to do is: Using a DC driver 18V or 24V, drive the nut onto the male fitting (via socket) When the driver stops or 'bottoms out', I'd like to translate the current spike (?mA) into a readable form in the PLC. After this value (assuming I succesfully translated the analog signal into a digital signal) is sustained for a given time period (? seconds), I'd like to send a PLC output (green lamp turns ON, and holding fixture unlocks) I'm using the FX series PLC brick unit. I am new at the analog signal processing. So, the analog factor will be my biggest obstacle. Does anyone know how this could be done? I'd be grateful for any advice during my attempt at this thanks -Ben

Thanks- I will wait and buy 24VDC lamps next time. Yes, the regulators are 7812.
