ArdEnvironment Station v1.0 WinCC-OA 3.15

#Sensor: Adafruit BME280

#Arduino: MEGA 2560 + W5500 Ethernet Shield

#Communication: i2c Protocol

SD0 -> SDA1 (brown-white)

SCK -> SCL1 (green-white/ethernet side)

5V -> Green (ethernet side) GND-> Brown

#Static IPs:

  • Arduino : 10.0.0.10
  • FieldPoint: 10.0.0.5
  • Linux: 10.0.0.4
  • Windows 10.0.0.1

(Subnet: 255.255.255.0)

#Config File (Windows Project)

OPC DA Client -> -num 10 -event 10.0.0.4 -data 10.0.0.4

[opc_10]

server="ArduinoOPCServer""ArduinoOPCServer.2"

[data]

keepLastTimeSmoothedValue = 1

#OPC DPT Creation

Manual DP creation

_OPCServer -> _ArduinoOPCServer

_OPCGroup -> _arduino

#Disable Firewall

systemctl disable firewalld

systemctl stop firewalld

(in case of FATAL error-WCCOdata(0) connection expired in Windows WinCC-0A, delete dbase.touch file in both projec(linux+windows) and restarts projects and vm)

#OPC Arduino

1.open Arduino OPC as admin 2.configuration-> Ethernet(10.0.0.10) and Port:80 3.close 4.register as admin 5.open Arduino OPC

(in case of arduino power off or ethernet disconnect unregister and register OPC via OPC Arduino)
