Automation professionals, I would like to read the display values of a red lion DP700 in a control logix PLC. I was able to successfully integrate both devices through EtherNet / IP and I am geting the corresponding values in a DINT register in the PLC. But the problem is that the value in the PLC register is not in the same format as in the DP700 display. The display reads the length of a product in inches like 288.484 etc. Where as the value in the register is a 10 digit number like 1133526516. For sure, there is a definite correlation between these two values but I am not able to figure out the exact relationship as a function of a formula. I have given below 25 data pairs for your analysis. I tried to find out the scaling factor (slope and offset). The scaling that I found fit the first 10 records but did not fit the remaining 15 records Can you help me to find out the relationship between the ? # DP700 PLC register 1 288484 1133526516 2 288627 1133531202 3 288631 1133531333 4 288739 1133534872 5 288741 1133534937 6 288742 1133534970 7 288746 1133535101 8 288757 1133535461 9 288776 1133536084 10 288796 1133536739 11 241060 1131482972 12 241043 1131481858 13 241027 1131480809 14 241032 1131481137 15 241055 1131482644 16 241038 1131481530 17 241078 1131484152 18 241025 1131480678 19 241030 1131481006 20 241037 1131481465 21 241040 1131481661 22 241023 1131480547 23 241053 1131482513 24 241041 1131481727 25 241077 1131484086

Currently we have a remote I/O module to connect with our PLC, yet it's not showing up whenever we try to connect it via inside RS logix 5000.

Could someone please printout the attached .ACD files for me? I need to reprogram this modified unit using a Micrologix 1500 PLC system and I don't have RSLogix 5000 software to view the old program it ran with before. Thank you!

Hi, I'm building an AOI in RSLogix 5000 to connect to a 3D Vision sensor. This sensor has an object called a Region Of Interest (ROI), the value of which I output from my AOI as "MyTag.ROI1", "MyTag.ROI2" and so on, up to as many as 20 ROIs. My question is this: Not every instance of the vision sensor will use all 20 ROIs. I want to be able to select how many MyTag.ROI# outputs are visible per each AOI instance, but it appears I can only toggle the parameter output visibility on a global scale. I don't want each AOI to have 20 outputs visible and hogging space if, for example, only 3 are used. On the other hand, I do want the outputs to be visible on the AOI block, and not hidden. Is this possible, and if so, how do I do it? Thanks

For all those who cant find a demo/trial version of RSLogix 5000 can download one from here http://files.rockwellautomation.com/UR/V17_Demo.zip Thanks.

Hello All, I want to read data from a Control Logix PLC, into a PLC5/60, using Ethernet and a MSG instruction in the PLC5. When verifying the MSG instruction in the PLC5, I get an error message. "Target Address in invalid". Once I figure out how to do this I need to replicate it in another PLC5. Scope is to read the status of 4 paint pumps controlled by the CLX. If any of the 4 stop, the PLC5 needs to know, because it is controlling the paint application equipment. Source data resides in a Control Logix 1756-L63. The tag is INT type, 4 elements long, and the name is PUMP_STS_B2. The IP address of the CLX is 4.2.6.230. There are 2 ENBT cards, one in slot 1, and the other in slot 3. 4.2.6.230 is slot 3. PLC2,5 / SLC Mapping has been created in the CLX. File=421 Name PUMP_STS_B1 and File=422 Name Pump_STS_B2. The file mappings represent a binary file created in each of the PLC5's B421:0~4 in Booth 1, and B422:0~4 in Booth 2. The PLC5/60 is Enhanced series E model using the Ethernet side card. The IP address of the PLC5 is 3.26.5.61. I also created MG file types in each of the PLC5/60. MG420:0~19 in each processor. This was necessary to use the MSG instruction in the PLC5. I have searched the forums for examples of how to do this with no solid results. I am trying to follow the best practices of reading the data into my PLC so anyone who follows can tell where it is coming from. While the IP addresses are not closely related they should be able to communicate. I say this because all of our PC's are on the 4.2.6.XXX network on a 255.255.252.0 sub net and we have no issue communicating with the 3.26.5.61 IP address. Any help and advice would be greatly appreciated. Regards, Mike Carter

I'm just starting to learn Ladder Logic Programming. I'm using Allen Bradley RSLogix 5000. I've been tasked with developing a 'Simple' Coffee Machine which operates like so: Toggle Push Button to StartDrop Cup (for 10 seconds)Feed Hot Water (for 10 seconds)If required, Add Milk (for 10 seconds)If required, Add Sugar (for 10 seconds)Procedure Complete - Illuminate Complete Light (for 10 seconds)I have implemented everything except the OPTIONAL add Milk & OPTIONAL add Sugar. Options are: To have a Coffee without either Milk or Sugar.Or have a Coffee with Milk and Not Sugar.Or have a Coffee with Sugar & Not Milk.Or have a Coffee with BOTH Sugar & Milk. I'm considering using Toggle Buttons to select / jump to a Subroutine (choosing the required ingredient make-up). But I'm wondering if there is another way to sequentially go through the procedure? Thanks. http://stackoverflow.com/questions/26930902/ladder-logic-simple-coffee-machine-optional-add-milk-add-sugar?noredirect=1#comment42839041_26930902

I'm having a bit of difficulty with the MSG function on a logix5000. I'm simply trying to get a REAL value ("BH5_Flow") out of another logix5000 and assign it to a tag in the PLC. I've created a MSG function and created a new tag "BH_5_Flow_MSG" for the message, and created "BH5_Flow_M" for the value that will come from the MSG function. When I click the "..." button to bring up the config, I put the following in: Message Type: CIP Data Table ReadSource Element: BH5_FLOWNumber Of Elements: 1Destination Element: BH5_FLOW_MIn the PATH tab, i then put the following in: Path: LocalENB, 2, [iP ADDRESS OF SOURCE MACHINE]When I test the edits, I then get the ERR bit activate with error 16#0004 when the message rung runs. Anyone got any ideas where Im going wrong? I've practically copied another MSG instruction from further up the ladder but it doesn't seem to work

Hi, we have a system that has multiple cabinets using guardlogix point I/O. For some reason that I cannot explain as of yet we sometimes loose ownership on one of the cards and have to reset it. Has anyone experienced this before and if so what was the cause and solution?

I need to change the IP address of an existing PLC. Only access I have is remote (VPN). Is there any issue with downloading the same program - with the IP address changed - to the existing processor? Then change the local network range to match, etc...
