Hi everyone,
Could someone help me with a small project?
I would like to read a 2-wire PT100, connected to the A0602 expansion - pin I3 and then publish the value via Modbus and then store it in a mysql DB. (I read from modbus with python code or modbus master for test)
I would like to use Arduino PLC IDE and LADDER. I tried every way but... on pin I3 I thought you could read the register directly (HREG 5) but it doesn't work (maybe I'm doing something wrong).
Having done this, I set a Status Variable at the first address 24576 (Hreg) and via ladder with MOVE object , I "passed" the value of the variable detected by the sensor to the other, and then published it at 24576 .. REAL to Unsigned 32bit. Nothing to do.. I read some values but nothing is correct and the numbers are not correct.. if someone had done a similar project (which in itself is simple) I would be grateful for the help.
Thanks in advance.
Kind regards.
