CAD DWG needed
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
This is what I figured I would have to do so I took a DWG of the PLC-5 and made it into a DNET Scanner. Now I am trying to find the DWG file for a PV550????? -
Hello, I am going to be designing and building a parts checker where I work and am looking at a few options. Basically I will have about 35 Digital Inputs, 25 Digital outputs, no analog signals, possibly a panel view 1000, and 1 incremental encoder (Allen Bradley 835T-33A was suggested from vendor for use if I bought a Micro 1100. Pretty sure it would work with the 1400 as well?). My question to the seasoned Micro Logix users is what would you suggest between the two? I am leaning towards the 1400 because of more embedded I/O and faster High Speed Counters which will be handy for my encoder. All I am going to use the encoder for is to see that my part being check did a 360 degree rotation. The RPM's will not be very fast.

How do I display System Hault Erron on PV1000
mr_electrician posted a topic in Allen Bradley / Rockwell Automation
Hello, I am trying to display a fault message upon S:1/13 Fault Error Hault on my Micro 1400. My touch screen is a PV1000. I can not get the message to display upon this fault. Am I correct in saying that this can not work since the PLC is not executing any logic under this fault condition? If so is there a way around this? System Hault Logic.zip -

Well that is a no go. I am not sure this is possible. System Hault Screen B.bmp -
How do I display System Hault Erron on PV1000
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
Thank you, I will try and monitor the S:1/13 directly and created a new alarm trigger for this bit in the PV. -
I am hoping you are not referring to me as the idiot! If you are then you should read your post to see how much of an idiot your are yourself. I can only build or design with what little to nill training in networking I have, and funding they are willing to pay. Ultimatley they will get what they pay for, and I will do my best to give them something that functions and delivers what they need. If I don't succeed, well at least I tried. They will have no one to blame but themselves for not using people with the right qualifications and training. If anyone wins it is me since I am sure I will learn something from this project. To those who offered USEFULL advise I thank you!

Have you tried looking into Main Task properties (right click) and removing it in there?

Produce and consume tag Via Ethernet
mr_electrician replied to mhi's topic in Allen Bradley / Rockwell Automation
The particular press is a 350Ton 3 station piercing press with 6 axis ABB robotic transfer. We also have a 1000 Ton blanking press and a couple 2000 Ton forming presses (all 3 employing SIEMENS 300's) -
Produce and consume tag Via Ethernet
mr_electrician replied to mhi's topic in Allen Bradley / Rockwell Automation
I second that suggestion. See attached screen shots of our ethernet communication to and from seperate plc's. -
Hi guys, I am using a micrologix 1400. I have a counter that bacically adds a value of 1 to the current value in N7:16 for every part that was inspected (N7:16 is my total parts inspected address). My issue here obviously is the math overflow fault that occurs when the counter gets reaches 32767 (which it has allready done faulting the plc) I have searched through forums and on Rockwells forums and in their liteterature and can not find any examples or suggestions on how to get around this. What do I need to do in the program so that I can allow my counter to count all day long as high as it needs to count with out faulting out?? Thanks guys

Hi guys, I have a question regarding the FM353 Stepper Motor Controller. Before I ask I want to clarify that I am more adapted to AB and my Siemens exposure has been limited. I am looking to get a stepper motor to rotate a part 360 degrees with accuracy to whithin 1 degree. I want to use RIO via existing profi bus. My question is does Seimens produce a stepper motor controller that works effectively and could be used on a RIO rack? I know AB makes stepper motor controllers for the compac logix and micro logix. I want to make sure I get the appropriate hardware with no conflicting setup issues. By the way our main plc that I would like to come off of for the RIO is an S7 300
-
Thanks for your reply. RIO is AB specific but I have a habit of using that term for remote I/O. I guess I am headed in the right direction then.

Math Overflow
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
2 Billion would be suffice but you know, I never thought of an external counter. That is a really great idea!!! -
Math Overflow
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
Yes this statement is correct. I want to count all parts that have been inspected during the entire life of the machine. -
I want to say a big thanks to everyone who helped me this year on my parts inspection machine. I just finished battle proofing the program and it is working great. The hardest part was learning the ASCII programming for the communication to the Keyence LG5000. I also want to say a big (this will probably offend some) MERRY CHRISTMAS and happy New Year and hope everyone stays safe. mr_electrician

Retaining counter values between downloads
mr_electrician posted a topic in Allen Bradley / Rockwell Automation
Hi there, I have a program I wrote and employs a few counters for part fail/pass total and so on. How do I set up the plc so that regardless of how many downloads I perform the counter values remain unchanged. I guess I need to no how to make sure certain bits remain in a certain state as well between downloads. I am using a micro 1400. -
Retaining counter values between downloads
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
This sounds interesting. I will try it out but I wonder if I have to upload the current values first as these consistantly change. Too bad the panelview could not do the counting logic and store it whithin itself, but then again if your changing it often then your back to the same delema. -
Retaining counter values between downloads
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
Yes reloading the values is what I have been doing. I was hoping there was a better way. Thanks for the fast reply!!! -
Hi everyone, I have a MicroLogix 1400 employed and currently am using the Ethernet and RS232 (CH2) port. This leaves me with Channel 1 which handles RS232/DH485. I have a spare Panelview 600 that I would like to use if possible but it has DH+ communication. My question is......is there a device available to make communications possible between the two devices?

Panelview 600 to Micro 1400
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
WOW!! These things are expensive. I am better off finding a used PV600 on E Bay with ethernet or DH485. Thanks for the reply though!! -
RS 232 Channel 2 on a Micro 1400
mr_electrician posted a topic in Allen Bradley / Rockwell Automation
Hi there. I have a micrologix 1400 that currently uses the ethernet port for PC and PanelView 1000 communication. I have a Keyence LJ G5001 controller that has an RS 232C port on it that I would like to use for data exchange to and from the plc. I tried to set up channel 2 on the plc and have DCOMM enabled but for what ever reason it doesn't seem to communicate. All the settings match such as baud rate and parity. Any ideas???? -
RS 232 Channel 2 on a Micro 1400
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
This is where I see activity with communication, however I do not see the LED lit up for channel 2 on the micro1400. -
RS 232 Channel 2 on a Micro 1400
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
Ok, I am at a total loss. I have tried and tried to make this work. I have no problems sending a command to the Keyence, but trying to read the responce seems to take a long time and the Keyence sends back a time out error. If I try it with hypertext then it works great. What would I be missing with the AB?????? I even tried clearing buffers before sending a comand and reading what came back. Also when I expand the ST file it really seems to lag down the computer speed?????? -

Actually I just figured it out. Crude programming but I am starting to understand and learn this method. -
RS 232 Channel 2 on a Micro 1400
mr_electrician replied to mr_electrician's topic in Allen Bradley / Rockwell Automation
Hi there, If I have a value of 2.55 in ST9:1, how do I go about making this a real number that can be used in a compare function?
