Hello All,
Not only am I new to Modbus but have never posted on a forum before so I hope this is ok.
I have a customer who needs to pull info from a Modbus slave into his wonderware SCADA. I am familiar with the registers formatted in the 30K, 40K format, but my current slave manual has all the registers in hex. I've got the registers that convert to three numbers figured out, but the majority of hex registers on my slave convert to four numbers.
An example is register 0x0E28 which is formatted as unit32 ro. I converted 0x0E28 to 3624. This is where I do not know what to do. I/ve tried polling register 43624 but receive invalid response. I am using CAS Modbus Scanner and a B&B 485-232 converter with a USB to serial.
Any assistance is greatly appreciated.
Thank you!
