Introduction

This document describes the protocol used by the MODBUS server of the module.
The OPEN MODBUS protocol is based on the widely known MODBUS protocol.
OPEN MODBUS is an open protocol and is not manufacturer dependent.
It is mainly used to connect PLC and I/O devices.

Why a MODBUS Server on the MSX-E modules?

Thanks to the MODBUS server, it is possible to manage an MSX-E module with e.g.: a Siemens S7 PLC.
The S7 PLC can start acquisitions and read data from the MSX-E module!

Technical details

Please note that only MODBUS over TCP is standardized. Nonetheless in this present
version the server implements OPEN MODBUS/TCP class 0 and one function of the class 2 even on UDP sockets.

The MODBUS/TCP class 0 defines two types of query: FC3 and FC16.

• FC3 functions read register content from the memory of the remote system
  
• FC16 functions write new register content on the memory of the remote system
  

• FC23 functions read/write registers content from/to the memory of the remote system
  

Characteristics of this communication channel as the standardisation document describes it are:

• The default port used by the server is 512 in both UDP/IP and TCP/IP. You can change this via the web server.
• Data are sent in network order, i.e. big endian (Motorola formata). Use the standard C functions
  atons/atonl and ntohs/ntohl to convert values bigger than 1 bytes.
• Datastructures used to describe parameters that are embedded in on-wire frames must be packed.
  How to do that is compiler-dependant.

The ADDI-DATA MSX-E Modbus server offers the following extension to the standard:

• It is possible to configure the server to accept data sent in little endian (Intel format) (native order)
• In this case, the default port used is 215. You can change this via the web server.

As answer to query a client may receive an acknowledgement (named standard response onward) or an exception.
If an exception or an error occured, you can use the GetLastCommandStatus command to get the real error number (from the remote server).
Real error numbers are described for each command in the "Returns" field.

The chapter below describes the available functions and their parameters.
It also contains the precise description of all frames implied in a given action.

Functions in this group are used to read values on the module.

For new application(s) or automate communication it is recommended to use the function GetLastCommandStatusEx.

FC23 (read/write registers) Functions

Top

Functions in this group are used to read/write values on the module.
This functions permits to call a write (FC16) and then a read(FC3) function in one command.
