Electronic Design with NodeMCU
min $50 USD / hour
I want build a Small Control Box with a Oled Display 0,96" one pushButton and a LED, A connection to a RS485 Bus and some Inputs 24V and a Relay.
The Box Receive from a PLC via RS485 a String with 15 Digits, has to check is that information for this Box. If yes it has to Display a String for the Order in the Display, and to switch on a Relay and the LED for Enabled. If the Operator press the Button the String has to be deleted, switch off the LED and Relay, and send a Message to the PLC. There are 3 other Digital Inputs 24V has to be read and send the changed State to the PLC via RS485. The Electronic Design and Software has to be made, I think on a NodeMCU or something like that. Max 25 Boxes in the RS485 Network plus the PLC
