Does M90 question fit here?
Anyway, I have M90-T1 with Siemens TC35.
Everything has been working fine for a many years now. I have a program running in my summer cabin and its' practically controlling everything (electrics, heating, burglar and fire alarm, etc.)
I have recently added a IO-PT400 box with one PT100 temperature probe. They all work fine. At the same time I have modified the program. It's more simple now. But for some reason some of the SMS messages stopped working. I have done a huge debugging, but somehow some of the messages don't work. Sometimes I get an error in SB180, but most cases it seems, like the message just disappears.
For example: Message
"Apua" does not work (Apua is "help" in finish)
but if I change this very same text to
"APUA" - just the text (nothing else) it starts working.
In ladder there are always reset coil for incoming message contact.
Next - and perhaps biggest problem is temperature setting.
I want to set temperature with SMS message. I want to simply send SMS with text:
TEMP 22
So the value 22 should go directly to pre-specified MI.
I have done a line in SMS settings, with receive bit on, acknowledge bit on, string in message is: "TEMP ##" whre ## indicates to a variable, which indicates to temperature MI.
Every time I send this message "TEMP 22" to M90, I have error in SI180: 11 (Illegal string received)
What am I doing wrong here?
The third question is about MI180 error messages. I keep getting errors 10 and 15 and they both are undocumented. Could someone tell me what these are?
And last question: Is there any symbol or character, which act as enter key? This could be very helpfull with receiving SMS messages. Also some special characters would be nice, for example degree mark. Is there any list or table available of these symbols.
Thanks!
