Split from LOGO!8 distributed network setup.

hello Elangop,

To do this, one would have to learn more about the sensors and how their signals are to be processed. Even if these then fit, you only have 32 analog network inputs available, so that the desired task is not possible with just one logo. You also have to split the program into at least two or use a larger PLC.

Dear ELLA_68,

Im using ESP8266 wifi module to give output in binary (NO/NC ) status of sensor.

I ll configure by network input in logo PLC but limitation is only 8 input can be used.

I ll use LWE for monitoring the sensor and controlling 1 Actuator valve for controlling water flow.

Is there any otherway to configure 64nos of sensors?

Regards,

hello Elangop,

you need several logos for this. Or you use Modbus IO modules and no ESP (but that won't be cheap!).

What might still be possible is an RPi or something similar that runs a NodeRed, IO broker or FHEM. This then combines the individual ESP queries into new values, which are then transmitted to the logo.
