Hello everyone,
I am very new to modbus and so I apologize if I don't use all of the lingo correctly.
I have a flowmeter that can communicate vis RS485 and I have a I-7530A-MR modbus to CAN converter. My logging system is CAN based so I am using the converter for the purposes of integrating the flowmeter into my data set.
The modbus settings for my flowmeter are:
Hardware address : 9
Integer Multiplier: 1
From the manual, it says all data is stored in 2 16-bit registers with length 2.
I am interested in reading register number 65 which is 0x41 and type 32-bit integer. This is just temperature because I figure it would be best to obtain data I can verify easily.
The communication modes available on the I-7530A-MR are:
Normal
Pair Connection
Modbus Master
Modbus Slave
Uart Switch
I am assuming that I need to set the I-7530A-MR to Modbus Master in my config.
I have the following options in settings:
Slave Node ID: 09
Function Code: 03
Start Address (high): 41 (not sure if this is correct for either high or low)
Start Address (low): 41
Word Count (high): 02
Word Count (low): 02 (not sure if this is what the flowmeter refers to as length 2 or not)
My hope is that I can get transparent communication for logging data from the flowmeter into my CAN network with this setup.
Again I am completely new to this, so as of right now I really don't know what I am doing so any help would be incredibly appreciated!
