But Modbus is a communication protocol. The register belongs to a specific hardware PLC.<br />
What PLC do you use?<br />
<br />
For example here at the bottom of page is mentioned under Modbus function codes - Data Access 16bit, but then in Implementing is mentioned also floating and integer &nbsp;32bit:<br />

Thanks<br />
I know about modbus and hardware<br />
<br />
I'm create my own modbus simulated hardware... &nbsp;I won't bother going in why, &nbsp;but I need it<br />
<br />
So I can store a 32bit value in each?

Thank you for the points and in the same time I hope my answer helps you and does not confuse you.<br />
In microcontrollers for example, you may have data as float or 16bit integer, but the hardware registers, the memory cell, can be only 8bit. Then for one float or long or unsigned int we need more than 8 bits and it uses more memory locations.<br />
The idea is that for Modbus you have 16bit registers, but also 32bit data, integer or float.

Hi<br />
<br />
I'm trying to find out what the max value I can store in one register on Modbus<br />
I.e. register number 40001<br />
<br />
I'm not sure if i can store 4, 8 or 16 digits<br />
i.e. 9999 or 99999999 &nbsp;etc<br />
<br />
Does anyone know?

Modbus - whats the maximum I can store in one register?

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

Programming

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

Programming Languages-Other

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.

System Programming

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.
