I've run the logloader routine on port com1, and that reported result=success once completed.
I then ran the enviromon r5.20.0, and things seem to have got worse. Whereas before the logload had been run, I could connect through port com1 ok, but unable to proceed beyond updating time ... operation failed, I now get an instant report of Warning, logger not found port com1.
If I attempt to connect with the logger e.g. through change converter address, it reports .... Get Logger Version - Operation failed.
Is it worth regressing the logload back to an earlier version of enviromon? Can you advise how I can recover and regain port com1 access to the logger. note - the connection through com1 was fine during the logload routine. I didn't disconnect the serial lead, but after the successful logload, the logger could no longer be found on com1. Not clear why logload found the logger, but enviromon cannot.
Realised what the serial port problem was. The PC defaults the com port setting to 9600, and I was setting the logger to this baud rate, when in fact I needed to set the PC to the logger default of 57600. Changing the baud rate to 57600 on the PC, conducting a clear, and reconfigure fixed it. Logger now programmed OK, and taking readings.
