Large Format, Graphics Compatible Display with ModbusRTU Interface
1 General
This display is based on the „migra SC/MC 5/3 Serial“, which is expanded by a
ModbusRTU interface.
The interface is used for the connection to a ModbusRTU controller (PLC) at
one side and the data exchange (RS485 frames) to the display at the other
side.
The frames for the display correspond to those of the „serial MIGRA“ and are
described in the User’s Manual „migra SC/MC 5/3 Serial“.
2 System Overview
The display is controlled with a ModbusRTU interface.

3 ModbusRTU Interface
The internal interface is the „ Modbus RTU Serial Gateway“ of the company
HMS (AB7010). At the enclosed compact disc you can find the documentation
and the necessary configuration software. Alternatively, you can find the files
at the home page of HMS (www.anybus.com).
The connectors for the configuration (RS232) and the controlling via ModbusRTU are accessible from the outside.

3.1 Display Control Via ModbusRTU
The display represents a ModbusRTU-Slave and is controlled by a ModbusRTUMaster (f.e. a PLC).
To change the display contents, the ModbusRTU-Master has to write to some
Registers. Therefore the commands “Force Multiple Registers” (function code
16d=10H) or “Read/Write Registers” (function code 23d=17H) can be used.
Here we assume that “Registers” are counted beginning at “0”. If your PLC starts
counting at “1” you may have to increase the register-address by 1!
The frames, which are described in the user’s manual „migra SC/MC 5/3 Serial“
(„02 81 80 8X DATA-Unit 03“), must be entered in the ModbusRTU output data
as follows:

The length byte and the MIGRA frame must be entered first. Then, the trigger byte
must be increased by one.
Thereby, the entered frame is transmitted to the MIGRA.
If the controlling happens without response frame („FC“ = 80H), the respectively
next frame must be sent approx. 100 to 200 ms soonest!
If you use the response („FC“ = 81H), the respectively next frame may be sent immediately after receiving the response!

The “Data unit” usually consists only of one byte (30H).
Note:
In most cases, you do not need the response frame!
The necessary frame intervals, which depend on the effort for the evaluation, can
also be found by trying.

Important note:
To change the setting of the DIP-switches obey the following order:
- disconnect the power supply
- open the housing
- open the dip switch protection cap (carefully - using a little srew driver)
- set the dip switches as desired
- close the dip switch protection cap
- close the housing
- reconnect the power supply
While the housing is open power may only be applied by qualified personnel and nothing has to be touched inside the housing at this time!
Otherwise electrical shock and danger to life may happen! Please be
careful!
