STR571 Help
Hi, I have an STR571 device set up as a master which is connected to a humidity sensor slave and currently displaying values read from the sensor. I have a Modbus datalogger which can save values to a memory card and want to connect the datalogger as a slave device to the STR571. Is it possible to get the STR571 to write values to a slave device which are being read and displayed from another slave and if so how?

Hi,
It is not possible to get the STR571 to write values to a slave device which are being read and displayed from another slave, but you can use the STR571 COM2 port. The COM2 is a slave, so you can configure it by a Modbus Node Slave and you can read the Holding Register Modbus using an external Master device. If an external Master can write in to your datalogger, I think you can run your application. Please check Modbus Registers list available by STR571 user guide (paragraph number 10).
Best Regards.
