I'm one of the ones that isn't aware... could you explain it briefly please?

I replied briefly on my mobile earlier, now I'm at the desktop I'll provide more detail. Ignition, by Inductive Automation is a full blown SCADA package. It however can do what you want, for free. There is a free download, the only restriction is a 2 hr limit (but this can be reset, infinitely). It includes an OPC-UA module which means you can run Ignition on your laptop and have it communicate over EthernetIP to your CPX. It can log to SQL databases, as much and as fast as your laptop CPU can handle. You don't need to create any MOV instructions. Launch the ignition designer and create a transaction group for the tags you want to store historically. Or drag and drop them straight into an easy chart for real time viewing (this also logs to an internal buffer, but the data wouldn't be saved for future reference as it would with a SQL transaction group). If all this sounds complicated, it's not. I'm setting up a CPX for a project here at the minute, once I have everything connected if you want I'll give you a Skype demo. Regards,

That would be the software you are using. What hardware are you using?

Most Useful Allen Bradley training
the_msp replied to a.murfin's topic in Allen Bradley / Rockwell Automation
For scada check out ignition by inductive automation. Free download, no limits except a 2hr demo licence. Connects to ab plcs via Ethernet -

Thanks guys
-
Thanks Jeremy, for the free SW for 1) does Rslogix 500 free only work with the 10 point PLC that was the case years ago... have they widened that limit? For the 1100 this would be preferable (due to the ethernet). But does it use RSL Micro which I believe supports 1000 and 1100 series A and B.. do either of these support high speed for use in 3) for stepper pulse train? (My project will utilise SQIM, Stepper, and Servo) Thanks

I left school and started a maintenance apprenticeship in the dairy industry. NVQ (National Vocational Qualification) in Engineering Maintenance, level 2 and 3. NC (National Certificate) in Electrical/Electronic Engineering. Was introduced to PLC's in the 2nd year of this. This was on a day release basis. After my apprenticeship I went on and did a HNC (higher NC) and then HND (diploma) in Operations Engineering (used to be called "Plant Proess Engineering". This was also on a day release basis. After that I left the dairy industry and joined the automotive industry. I started a B.Eng in Mechatronics upon joining it and am about to enter my final year. I'm now a Systems Engineer and work mainly with National Instruments (LabView, TestStand etc). My degree is online... the university is a 3hr drive away. I go down 4 days per academic year for lab days and of course for exams. Obviously I don't know the canadian academic routes. But based on what you've said Mechatronics sounds like what you need, or pure electrical/electronic. For an apprenticeship day release should be approved by your manager (and you should be asking him the same question you asked the forum). HTH, Regards p.s. I think once I heard a statistic that Harvard offered one of their traditional, class room taught courses, as an online course. IIRC, they had more applicants for the 1st year of the online course than they had had cumulatively for the history of the class room taught for the same subject.

Hi, about to enter the final year of my degree and will be doing a year long project. Could spend half an hour on the AB website or 30 secs here apologies if the questions have been asked before... 1) What AB MLX range has the free software? 2) Can any of the MLX w/E-Net talk to 1734-AENT Point IO? I think it is only for CLX/CPX as it uses CIP comms protocol? 3) Can any of the MLX communicate with servo drives? Was in with my AB rep ages ago and he was suggesting a CPX kit. TIA

DSC module?

ASForrest liked a post in a topic: VPN vs RDP

My company uses VPN, CISCO at that. I don't use it much seeing as I'm on site 99% of the time. My company employs 1250+ people and has 3 manufacturing plants (2 in UK, 1 in USA). My IT department did the complete setup so I have no knowledge of the internal workings. All I do is open up the software, think it's called "CISCO Iron port" when I'm remote, click connect, and I have all the features that I do if I was on the company LAN. If you want exact software details let me know and I'll check tomorrow.

Multi ML1400 to main panel View Plus 12.1HMI
the_msp replied to ALI PLC's topic in Allen Bradley / Rockwell Automation
OK you can optomize your data transfer e.g. for bools instead of transferring them one one bit at a time, transfer the whole word. You would need to group them together as a word when you program Regards, -

Multi ML1400 to main panel View Plus 12.1HMI
the_msp replied to ALI PLC's topic in Allen Bradley / Rockwell Automation
Sorry I don't have any sample code, I havn't tried this method myself was just throwing it out there as a thought... Try searching the forums, both here and plcs.net Here is one thread that advises to stagger your msg instructions (do not have them all executing at the same time) http://forums.mrplc.com/index.php?showtopic=24093&st=0&p=116407&hl=multiple%20msg&fromsearch=1entry116407 How much data are you transferring, if you only need 10 HMI pages for 21 PLC's? How fast does the PLC have to react to the HMI read/write operations Regards, -
Multi ML1400 to main panel View Plus 12.1HMI
the_msp replied to ALI PLC's topic in Allen Bradley / Rockwell Automation
What is the exact model number of the PV+? I worked with one (10") around 4 years ago, and if I recall correctly one limitation of the plus series is that it is limited to 25 pages... will this be enough for your 21 PLC's? If this is true for your version, then would you have enough space on 1 screen of the HMI per PLC you are controlling? There might also be limitations on how many devices you can browse from one PV, I'm not sure on this. If so, instead of having your PV talk to 21 separate PLC's, it might be a better idea to have all the PLC's talk to a master for example using MSG instructions) so to speak, and have that one PLC pass this data onto the HMI. Also research CIP connections. My system 4 years ago used CPX not MLX, but just read another post which includes "If these are PanelView Plus HMIs, they can establish up to five CIP connections each"
