@Nugro I have check this device feature on product site https://www.pusr.com/products/din-rail-rs485-serial-to-ethernet-converter-usr-dr302.html I think it can config to be Modbus gateway then you can use Modbus TCP on Predefined protocol or Simple communication function in FX5U to communicate with device.

When you adjust something in parameter you need to download Program + Parameter to PLC that mean you need to stop PLC in download process then run it again after complete.

@Dadde for testing you maybe use MX Component with MX OPC Server (or OPC UA Server if need) that could access with GX Simulator 3 then connect with your SCADA with OPC driver.

Have you try this [OMFINS]Source=1/1/0Block=256 and check that your firewall have block port TCP:9600 or not.

Could you show us your OMRON Ladder diagram to be convert them on SoMachine Basic?

On Your Slave Address in Read Command you assign them to be D0 then you should [ MOV K1 D0 ] to assign slave address to be 1

@Kim Jessen Do you need to connect PLC LOGO!8 to RS Pro HMI by ethernet connection alright? RS Pro HMI seems use Wecon PIStudio Software for configuration. On your example video is configured with S7-1200 with S7 connection. For use with LOGO!8 they can use with S7 connection too by compare LOGO!8 variable to be in DB1 like this link https://www.promotic.eu/en/pmdoc/Subsystems/Comm/PLC/LOGO.htm but you need to familiar with TSAP Local / Remote setting I recommend to open Modbus TCP Connection on LOGO!8 then use Modbus TCP driver on RS Pro HMI is easier to connect it.

If you use LOGO!8 for V8 or later it can be set communication to be Modbus TCP Server then you can use any HMI Touchscreen that can use with Modbus TCP connection.

For FX3U-232ADP-MB you could set your PLC to be Modbus Slave then connect with Citect by use MODBUS driver on Serial Port.

Hi @dalmadi.norbert Could you connect with your device. If not please shared program on communication to us to help you find problem

Maybe you need to use MX Component or MX OPC Server to link with GX Simulator 3.

@Maryn From this FAQ I think it could but when you use with TM3 modules need to attach after them. https://www.se.com/ww/en/faqs/FA235150/

I think they have not downgrade tools but I think almost instructions are same as FX3U. Maybe you need to print their program then rewrite in GX Works 2.

@vtripathi How about your wiring and which module do you connect? Please show us your program for check.

@Maryn You need to read data from analog input (They are in %IWX.0 or %IWX.1 depend on which channel do you use) then use compare block to enable with output.
