Arduino Opta and Modbus TCP

[cmil413]

Hello, all.

I recently got an Arduino Opta (the WiFi-enabled version) to use as a micro PLC for control-system application (6 temperature sensors and two vents). I currently have the control system assembled, wired, and ready to go in the field. My only problem is that I don't know how to see/log the data from my office. I have been banging my head on the desk trying to get the Modbus TCP comms up and running, but I always get the red ERROR bar when trying to connect. The USB connection works just fine, but I want to be able to access the data from my computer.

So, I guess I have two questions:

1. How to set up the Opta to be programmable via Modbus TCP? and
2. How to log/save the data remotely (is that also via Modbus TCP?)?

Any help is appreciated! Thanks in advance!

EDIT: I'm using Opta v1.1 and PLC IDE 1.0.6.

Sadly Modbus over TCP has been removed on PLC IDE 1.0.6.

Configuring the Opta Ethernet Port

Hi, I am trying to connect the Opta to my local Ethernet network for the first time. I want to connect to it and set it up as a ModbusTCP server. I am not able to ping the IP address and there are no no link/activity lights on the Opta when connected to the switch, however there are activity lights on the switch port. Occasionally bot the link/activity lights on the Opta flash red. I following the tutorial opta-modbus-tcp-plc-ide I am fairly new at this - I got my Opta out of the box, wired it…

This clearly limits a lot of potential uses.

Ah this is quite unfortunate. So at this point, it's just a glorified, beefy, regular Arduino board?

Thanks for the info.
