I am presently working on Siemens S7-1500 PLC. I configured the PLC as modbus client. Now, I am trying to read the holding registers using Modbus read. But unfortunately, I am unable to establish the connection, The status on the node shows "Initialize" changes to "Error FSM not ready to read at state INIT" and then reconnecting. I have no clue how to solve this issue please help.
I have also tried using node S7 node to connect the PLC but as soon as I enter the IP address and deploy it the status on the node changes to disconnect.
Please give your valuable suggestions.
