Modbus Addressing Ignition Manual

Use the manual to get one tag working, then roll out to all the others

Since the table has address offsets given in hex, you will need zero-based addressing in the device advanced options.

Thank you for the quirck reply. really appreciate it. this is what i set on the address configuration. Is the radix 8 the correct to read values in float format or should I use 16?

Do not use the address mapping feature. Create OPC tags with manually constructed OPC Item Paths, using the documentation linked above.

this is confusing to me. I am searching information in the internet trying to learn this

Put the high byte and low byte together and convert from hex to decimal. That will give you the decimal address to accompany IRF.

11

Could site an example? what to type in the item path?

12

[deviceName]IRF0
[deviceName]IRF2

and so on.

I am able to read the address 00 04

Value in the energy meter matches the value displayed in ignition

How about this one?

Hex B0C is decimal 2828. So five tags, [...]1.IRF2828, [...]1.IRF2832, [...]1.IRF2836, [...]1.IRF2840, and [...]1.IRF2844.
