Node red to HMI connection

Hello, I want to ask a help in my project. I am creating a single monitor for multiple machines in our company, the problem is. I cant use Omron PLC to create a connection, only in HMI. I tried to communicate using node-red-contrib-modbus protocol, but in Modbus-Flex-Getter node it signaled its active but, I cant get any data from HMI. hope you can hep me to get data in HMI(MONITOUCH V9080ISD).
