  1. Hi, I've been given a couple Twido PLCs (TWDLCDE40DRF) to create and test modbus communication between devices and a HMI/SCADA software, as of now I haven't been able to work due to IT restrictions (hopefully this will be adressed in the next few days) I can't disable firewalls nor can I manage COMs ports.  My question is, when creating a Master/Slave between a SCADA (master) and a PLC (Slave) do I need to write any code in the Twido PLC, or I just need to configure the ports/adresses to be able to read the info in the plc? Disclaimer: English isn't my first language.   Thanks in advance. Edit: Fixing writting.
