HMI Documents  HMI manual.pdf

Hi, so far  i got some documents from the manufacturer, while trying to study the documents, please i will still need more elaboration from this forum thanks  electrical diagrams.pdf

Hi, please I wish to develop project like this: I wish to control my flow transmitter using PLC. For example If i wish to pump 1000, 2750 0r 3800 gallons of water into my tank;  the command should be given from RSLogix 500, after pumping the 1000 gallons the valve should switch off. They should be a possibility were the task can be done anytime inputing different amount of gallons. I wish to use Allen Bradley 1400 PLC to perform this task. I know analogue card will be required, now how is communication established between the card and the flow transmitter? My flow transmitter does not support Ethernet option! What types of instructions are used in RSLogix 500 to build this type of application? controlling transmitter flow rate with AB 1400 PLC.pdf

Hi sir, thanks for the reply. am working hard to get the documents.

Hi Joe,  i have written to the company. but no respond yet. i even called the technical support center, it seems the receptionist is not all that conversant with English language, how ever she said i should get back to her by 2 pm Italian time today.  

please here is the project.  PLC1.RSS

thank you very much sir' you have made enough effort to encourage me , sincerely i appreciate . thanks once more!

nope, before i visited the location the HMI was not powering up. i have written to the company who did the job. requesting for some documents they are based in Italy     

Sir, i think before talking of replacing the HMI, i should get some better understanding how the program functions, for example i need to create an application in the HMI that enables the operator to target the quantity of product he need, like when he inputs 1000 gallons, once its achieved the valve switches off automatically !  so please i need some guidance on how to approach this task  

Hello Sir,  thanks for the reply, the HMI does not  power up at all.

Hello Sir thanks for the reply. please let me use this opportunity to brief. i was called to check on this control panel, the human machine interface is bad that is panel-view 600. the main function of this system is to measure a required quantity of chemical into a mixing batch, for example the operator may require 1700 gallons he will input values in the HMI and press the start button once the amount gets to 1700 gallons the control valve will switch off automatically. the system has about 5 flow transmitters operating.  now since the Allen Bradley panel-view 600 is bad, my ideology was to upload the existing program from the PLC study it and see how i can create the same function for another HMI from you feedback, please it maybe i did not get you well, does it mean that  the program i uploaded from that PLC is not related to the application i have explained ?.  the are no diagrams for this control system nor any project files for the ladder logic diagram, nothing was documented. i have writing to the manufacturer hoping he responds. best regards.    

ok thanks 

Hi thanks for the reply  the program includes the subroutines in that pdf  from file 165 is subroutines 

Hi please, am trying to upload a program from  PLC AB 1400. When a message pops up asking me if I wish to go online, and i accept. another message will appear saying program in the processor has changed causing an offline state. please i will appreciate any help thanks    RS logix 500 indicates program in the processor has changed.pdf

Hi, please I wish to understand something, I understand communication for AB 1400 and Delta HMI can be achieved using RS 232 communication cable and wiring the pins according to HMI manual specifications. Now I don’t have RS 232 communication cable, but I have VGA 9 pin male and female communication cable, Please any idea on how I can communicate the PLC and HMI using 9 pin VGA male and female ? How can i use VGA 9 pin male and female to communicate from my PLC to HMI.pdf

thank you for the reply  i have the DP 9 Adapter male and female, the i model i have i can open it and do the connection, now i wish to understand once more please, can communication for the AB 1400 PLC and Delta HMI DOP B07S411 BE created using the DB 9 Pin male and female ?  Wirring DP 9 adapters.pdf

Hello thanks for the reply, i want to upload from the PLC. the PLC got a program inside already. 

Hi, i uploaded program from my Allen Bradley 1400 PLC. when i tried to go online, a notification pops up showing program in processor has changed causing offline state do u want to upload, when i upload the same information comes up Uploading from PLC.pdf

Hello, please i wish to know the right communication cable for Delta HMI DOP B07S411 and Allen Bradley 1400 PLC

Yes  i did 

 Hi, after implement the following steps to configure my Allen Bradley 1400 programing logic controller, I tried uploading program from the PLC, a got a notification displaying (no respond from processor at selected path/node) please will appreciate any help to rectify this error uploading program from AB 1400 (1).pdf

Thank you, the system worked well after following the guidance you gave. now i got one more issue, when i tried to go online a message pops up saying program in the processor has change causing offline state do you want upload ? even if i upload again without any changes the message still comes up will appreciate more guidance.    Uploading from PLC.pdf

sure i did not change the file,  after uploading a notification pops up do you want to go online i accepted and the message came up program in the processor has changed causing an offline state !
