For the present, I'm testing with a dummy variable (time in seconds). Eventually, I want to interface the Nano-10 to legacy plant e.g trade waste systems that currently run PLC's capable of Modbus RTU and in effect provide a Pachube logging gateway function through the Nano-10. The variables of interest would be pH, temperature, tank levels etc. The other alternative I am considering is one of the Arduino boards with Ethernet/SD card logging and RS485 ports which are also able to log to Pachube type services inexpensively. The Nano-10 having all the basic interfaces and with 24V I/O appears more attractive in industrial context

Thanks for the code snippet. I tweaked my code a little and its now working. Thank you very much for your help.

Glad to see this thread. I too am interested in getting a nano-10 PLC to write to the Pachube service. As per suggestions, I managed to put data into the Pachube service via Telnet successfully, then tried the same via the PRINT #4 statements. Two problems become show stoppers.

1. The total string size via PRINT #4 is limited to 70 characters, while the complete text for the Pachube transaction is much greater than this; 187 characters in my 1 channel example
2. Splitting the text into multiple PRINT #4 lines does not work as each PRINT #4 adds a <CR> character at the end corrupting the transaction text required by Pachube

Are there any workarounds for this? Could there be a PRINT #4 statement that does not insert the <CR>? It would be really awesome if the nano-10 can be used with the Pachube or similar services
