Support Questions / Ethernet Modbus write

« on: January 21, 2016, 08:19:17 PM »

I think I've missed something simple.  I've mainly played with monitoring on some live control system until now but today I setup a test PLC to try to learn more and while I can read an address, 400400, over modbus.  I don't seem to be able to write to it.  I've tried a MultiStateSelector and a SelectorSwitch with no luck.  Is there something I need to do to enable writing?

Support Questions / Reading common text from a variable

« on: January 03, 2016, 09:45:25 AM »

I started playing with the AdvancedHMI last night and have been very impressed so far.  It was very easy to get started on and functioned very well with a PLC I was accessing over a cell modem.

One thing I'm sure it is capable of that has eluded me is how to have common text use the same variable.  For example "output 1" on that system is the "Trash Pump"  It is used on the HOA text, the output states text, etc.

So to start with we use a color coded MessageDisplayByValue for our HOAs with different text for each value as follows.
0 = Trash pump auto off
1 = Trash pump auto on
2 = Trash pump off
3 = Trash pump hand
4 = Trash pump faulted

What I would like to do is have a variable textoutput01 so that the text assignment would be something like...
0 = textoutput01 & "auto off"
1 = textoutput01 & "auto on"
2 = textoutput01 & "off"
3 = textoutput01 & "hand"
4 = textoutput01 & "faulted"

Then be able to change one instance of the text of textoutput01 and have it change everywhere.

Thoughts?  Thanks, TW
