Hi, 

 

We whant to get value from an honeywell PLC and we choose to use the modbusTCP interface. I did use the POINDexter to verify that i could communicate with my modbus Slave and all seemed good. 

 

I want to read from 2 holding register in the PLC. I am not sure my Pi Point configurations are good since in my system explorer i get a value of configure in the attribute connected to my pi point.

 

Here is my configuration : 

Location 1 : 1 (the interface ID) 

Location 2 : 7 ( the modbus slave ID) 

Location 3 : 603

Location 4 : 0 

Location 5 : 1

instrument tag : the ip address of my modbus slave. 

 

is there anything i missed ?

 

 

Thanks!
