Support Questions / Connections to a SLC 5/01 DH485
« on: March 21, 2013, 08:06:56 AM »
I'm curious if AdvancedHMI has ever been used to communicate with a SLC 5/01 with only a DH485 port? If so, which adapters - PIC or UIC or both?

Support Questions / EthernetIPforCLXComm ReadAny() sometimes returns SequenceNumber
« on: March 19, 2013, 02:19:38 PM »
After getting some time to look deeper into the issue I had posted about in the Support Questions category it appears that sometimes the driver returns the SequenceNumber from ReadyAny() rather than the expected array of strings. It must be misinterpreting AsyncMode to make this happen. I believe this is the same issue as discussed at http://sourceforge.net/projects/advancedhmi/forums/forum/875091/topic/6729354 and I am using the 3.26 beta.
I'm not yet familiar enough with the code to fully understand how AsyncMode is being used, among other things. It looks like the driver's AsyncMode property is temporarily set to True in PollUpdate() so I'm guessing that it's possible that the ReadAny() call that I'm making is sometimes corresponding to this brief period while components on the form are updating. This wouldn't explain why once the bug manifests it is persistent, though.
Any insight, advice, or suggestions?

ProFace touch panel connected to ControlLogix PLC
I really want to thank you, Archie! Next we're planning to add communications to a SLC that controls the base machine functions.

Feature Request / Component event hooks
« on: March 13, 2013, 09:57:57 AM »
I'd like to see the basic components have built in public event hooks. I'm currently using a timer to poll the state of a PLC tag that is also used in an indicator. I'm using a state change to drive a large read so that it doesn't poll continuously. Eventually (when I read up on VB coding events) I'll write events into it, but I think it'd be handy to have these "out of the box".
As an example of my current case: BasicIndicator1 could have events for option2On, option2Off, option3On, and option3Off.

Support Questions / Issues with ControlLogix communications
« on: March 13, 2013, 09:47:59 AM »
In the HMI I've written I'm communicating with a ControlLogix PLC. I've seen the issue mentioned over at the SourceForge forum of the addresses being read in with ReadAny() pulling in a maximum of 59. I've found this to be the case in my project as well. I need to read in 2 arrays of 100 DINTs each, so I'm handling this by pulling the data in chunks of 50.
The main issue is that every once in awhile the data returned will be incorrect. The values in the tags are guaranteed to all be in the range of 0 to 100. When the error occurs only a 1 member array is returned with a value of >100. Once this is occurs it is persistent - ReadAny() will only ever return a 1 member array with an incorrect value until the program is killed. Relaunch the program and reads work fine again.
What would be the recommended way to handle this? Maybe there's a good way to programmatically reset the driver?

Support Questions / AdvancedHMI on Pro-Face touch panel running Windows XP
« on: March 07, 2013, 06:12:38 PM »
I really hate it that my first couple of posts here are going to be support requests. I hope to have some screenshots to post of the interface I'm working on soon. I want you to know that I really REALLY appreciate the software! It's damned amazing! I just downloaded the libs on Monday & have already used it to help me breeze through most of a fairly complicated HMI in the time between my other tasks at work!
I don't have all of the pertinent information at my fingertips right now, but I will get it posted in here tomorrow at work. Mostly I was hoping there might be a known issue & workaround.
The PLC is a ControlLogix, the touch panel is a Pro-Face running XP. I'll update with the model tomorrow. When I try to run the built app on the Pro-Face the app immediately crashes. The communication test app I wrote just had 4 tags being read into 4 BasicLabels - 1 controller tag & 3 program tags. It worked flawlessly & was able to read & write fine. After adding a few more controls it began crashing as described. I haven't had time to try adding & removing things to see if it is something specific. The issue does NOT manifest itself on the laptop running XP that I'm using to write the app.
Don't know if this will help, but the data that comes up on the error report dialog is:
Error signature
BCCode: 1000008e
BCP1: 80000004
BCP2: 806EDAE1
BCP3: 9AFF975C
BCP4: 00000000
OSVer: 5_1_2600
SP: 3_0
Product: 256_1
As I say I'll try to get more information on the panel model, etc. Hoping it's a known issue with a known fix, though!
