Hi guys, I have two controlwave micro RTUs setup one as Master and the other as Slave. The slave is the one sending the Handoff Data to the Master.
I'm using a custom function block to setup the modbus communication for the handoff. I have a Radio in between these two RTUs being connected to the RS232 port on both ends.
I had the same exact setup at a different location, the only difference that other location doesnt have a radio in between and its just straight hardwired to the rs232 comm ports.
This setup with the radio I'm completely at a loss. When i pull up the List of data that i should be getting the data is constantly changing. For example I'm calling for 20 registers. I'm sending 32bit floating point data. for some reason the data in the registers is changing every cycle.
I dont understand, why is it changing? i shouldnt matter how fast or slow i poll the rtu i should get the same data if same data is being sent. Could it be that the radio is somehow messing up the data being sent by the Slave RTU?
Thank you,
