Hi everyone,
Thanks for all replies and specially Jasper. Here is some followup
since this thing still refuses to transfer...
I had some time today to look into it and actually everything is
supposed to be very simple and straight forward.
Display boots up and loads some demo. Once you exit there is little
launch bar with four buttons. Clicking on Transfer button will
make display wait for Protool signal. Easy...
Clicking on:
Taskbar > Programs > Communication > Remote Networking \
you can see (and edit if needed) all present connections.
Configuration and transfer are using COM2, while COM1
(IF1A and IF1B) is to be used with PLC. Very simple...
Now you go to:
Control Panel > Communication > PC Connection
and select one of the connections defined under "remote networking".
There is one checkbox to "Enable direct connection to the desktop computer".
Default connection was "Default_115200" which in our case was
already modified to use different baud rate (19200,8,Hardware,1stop)
but this should not be a problem now that I know what is the setting.
There is one more thing about transfer:
Control Panel > Transfer > Transfer Setting
This window has settings for:
Channel_1 (serial)
[ ] Enable Channel
[ ] Remote Control
Channel_2 (MPI/Profibus/Ethernet)
[ ] Enable Channel
[ ] Remote Control
It looks like this is the PLC interface (COM1 or Ethernet) so
it shouldn't matter at this moment.
I tried all combinations while varying following (just for the heck of it):
- crossover cables (simple 3-wire null-modem, 1746-CP3, version
from Mr. RRobins which is at the top of this tread etc.)
- Handhsaking (none, hardware, software)
- baud rates (19200, 38400 and 115200)
- COM ports 1 and 2 (the TP270 display)
Siemens tech guy suggested rebooting display after each change
but this didn't do anything either. I am positive that all
I did was just fine. I am suspecting problem in either Protool
(it's latest version, so it's hard to beleive) or the display
itself (maybe dead com port). If anyone should have any other
suggestion, please shoot...
