Modbus interface
4 Modbus interface
4.1 Standard Modbus
Communication takes place via the Modbus protocol.
After the connection between the client (master) and server (slave)
is established, the master sends Modbus requests to the server.
The result is returned as a Modbus response.
The PDU (Protocol Data Unit) defined in the Modbus protocol is
independent of the underlying communication layer. The PDU
consists of "Function Code" and "Data". The Modbus ADU
(Application Data Unit) for "Modbus via the serial interface“
comprises the address field, the PDU and a postfix checksum (16
bit CRC).
The "Function Code" of the message determines the Modbus
service to be performed. Depending on "Function Code", "Data"
includes additional information.
NOTE!
 For more information on the Modbus
specifications, see reference document "Modbus
Application Protocol Specification", page 6, chapter
1.3.

4.2 Expanded access via Modbus "Function Code 43/13"
4.2.1 CANopen TCP/IP Interface
In addition to the control via standard Modbus, access to further
parameters is possible via "Function Code 43/13". See page 6,
chapter 1.3 "Reference documents", document "Interfacing
CANopen with TCP/IP". You may read and set the parameters of
the control unit and all inserted plug-in modules via the expanded
access.
4.2.2 Module addresses
The MGC-PRO control unit is modularly built. Every plug-in module
has a unique basic address. The module address is the sum of the
basic address and slot number. This enables operation of several
equal plug-in modules like two detector modules in the same
control unit.
Basic
address
Module
0x01
0x02 MGC logic and motor control
0x09 Detector module
0x18 Radio module
0x20 Ethernet Module
0x28 RS485/422 module
Table 11: Module addresses
The RS485/422 modules thus can have the addresses 0x28 to
0x2F. To be able to access parameters of the RS485/422 module,
the module address must be known.
4.2.3 Supported commands
