Hello All,

I want to make communication with omron plc with node red without using physical plc.

Installed omron fins library.

Created program in cx programmer and started simulation(cx simulator).

Plc configuration : 0.1.0(fins)

Port :9600

Running node red and omron plc software in one system.(local system)

Defined local ip into nod-ered configuration.

Status return connected, but can not read address from the plc.

Timeout error.

Do, How to resolve it?

Hi. I wrote the Omron FINS nodes. IIRC the simulator doesn't (or didn't used to) provide a way to communicate with it. (I haven't used it for a few years, things might have changed)

I did however write Node-red flows that permitted FINS communication to simulate read/write from/to the Omron fins nodes which was pretty simple.
