Support Questions / Component Properties Macros

« on: September 14, 2021, 01:37:59 PM »

Just simple question asking in regards to what are some of the marcros used in the properties for the various components added with AHMI. To be more concise on what im saying an example of a macro i was curious about is how with a modbus address that is a string, you have to specify that the address is a string and its length E.G. 400001S20. Now are there any other sublties that a programmer should be aware of when coding. Additionally, I'd like to know if its possible to manually enter a newline character "/n" on a text field within a component's properties.

Support Questions / AHMI project freezing and low on memory

« on: February 12, 2021, 12:31:59 PM »

I have a project that is being implemented on a system that consists of a Click PLC and AHMI program that control a Centerless Grinder. After a while the operator reported that a message popped up saying the system was low on memory and has on multiple occasions no control over the HMI. To alleviate the issue of the the low memory I turned off some background apps but the problem still persisted. Additionally with the freezing issue the HMI wouldn't allow the operator to interact with the machine but interestingly would still update the display with data from the PLC. My best guess is that within the program I didn't manage resources effectively with a buffer of sorts that expands infinitely, but was curious if anyone had experience with the same issue or has any ideas as to why.

Any input is appreciated

Support Questions / Re: Generic TCP Client

The actual computer is still a serial connection to the etherpath module the only difference between the simulation and actual is how the data is sent.

Support Questions / Generic TCP Client

« on: October 12, 2020, 02:52:31 PM »

I have a question related to the Generic TCP client component. To give a little background I have been using this component on a test system that consists of 2 computers and a Etherpath SS1 module. One computer which I'll call the sender consists of a PuTTY instance running on a serial connection, connected to the Etherpath module via a null modem connection. The other computer which I'll call the receiver has the AHMI program running with the generic TCP client which grabs data from the putty terminal via ethernet connection to the Etherpath. The system when I test it works perfectly but when I try to implement it into the actual system the GenericTCPclient.datareceived method doesn't interrupt when data is sent. I believe it has to deal with the communication protocol as its an ISO protocol in which there are acknowledgements to specific bits sent. So my actually question would be is if the GenericTCPclient can handle ACK, SYN, STX, ETX, etc. or would there be an issues that would arise when trying to handle these characters?

No they came with the AHMI suite.

Those controls change color depending on the output from a third party. As seen in the captures the images should be identical but the one that is accessed through Internet Explorer produces the skewed result. We've also tried it with Firefox with similar results.

Support Questions / Simple Webserver Display Issues

« on: September 04, 2020, 12:03:03 PM »

Im having a strange problem with an HMI that I'm trying to broadcast through the web using a SimpleWebserver component. The issue specifically is that when I run the application and access it through its IP address the HMI has layering inconsistencies from what the actually HMI looks like when viewed locally in Visual Studios. For instance text that is supposed to be invisible is visible, text that is set to front isn't being displayed, etc. I have also provided photos of what the HMI looks like when run in VS (Capture 1) and when viewed from a internet browser (Capture 2).

Support Questions / Using ethernetIPforCLX with AB tag database

« on: July 17, 2020, 04:47:31 PM »

Ive been looking for the correct way to write a tag's value from an Allen Bradley Compact Logix to a component in VB. Currently I have been using the EthernetIPforCLX, inputting the IP address of the PLC, and using the Syntax (Program:MainProgram.TagName) in the place where I would typically put the modbus address of the tag. My issue is that when I run I get a PLC com error. Im not sure what my issue is, my only thought is that I would have to input the tag database but since I call the IP address of the PLC its seems redundant. Any help is appreciated.

The fix worked beautifully, thank you both for your assistance.

Support Questions / Input string was not in correct format

Attempting to grab the text of a selected recipe and display it in a basiclabel. The issue is that when attempting to do this using code the definitions are of varying type and throws an exception even though it builds correctly and says that it is a generic function. I believe the issue is with the "item" object but not sure how to work around this.
