Modbus Coil Status
I am not getting the correct values...
I had to check the Contiguous batches only and the analogs started working properly.
The controller I'm talking to is a Siemens 353, in the opc server on other systems I have to set the max coil read to 32, or a low number, I can't find it in the newer manual I have...
I have everything working in a KEPserver, and the only thing I have not gotten working in mango is the coils...
any suggestions would be greatly appreciated.
I'll need a bit more technical info. Can you provide message traces and such? Also, you know that Mango's Modbus is 0-based?
Thanks for the quick reply!
That was it...
I had added all our analog tags first, and they all worked fine, so I didn't think about it..
I do have another small issue though,
Getting a lot of these...
Exception from modbus master: Unrecognized Windows Sockets error: -1: socket available
Now, I am running this on their server 2008 64 out there, I can run this on anything I want...
I've seen those errors too. I don't know how to get rid of them, but i also don't recall that they actually caused any problems. Are you seeing otherwise?
no, no problems at all.
as we added more sites and more tags, the watch list update is a little slower sometimes, but that is to be expected.
How many points are you updating, and how often?
6 controllers with about 20 tags each.
2 local and 4 radio.
will be adding about 4 more on the radios, and about 20 more tags to each.
now polling every 30 sec, will probably change the radio sites to 1 min...
Hmm, that shouldn't be much load if the Mango host is a decent box. Can you quantify the watch list slowdown?
not yet, I was on my laptop with verizon wireless connection at a meeting the other night.
A couple of them took about 5 to 10 seconds to update when switching between them.
although we are also running a virtual box with the old wonderware polling the same points on the same computer...
I'll know better next week.
I'm on vacation right now...
