Large Displays Numeric LED with Ethernet TCP/IP/ Profibus DP/ Profinet / Serial Interface

1 General

The product series “migan FI/SI“ is available with the following optionally interfaces:

 Ethernet TCP/IP
 Profibus DP
 Profinet
 Serial (RS232 / RS485)

This 7 segment displays are designed for professional use. Depending on the type
of device they are suitable for indoor or outdoor use.

The modular design allows for cost-effective models of various interfaces
with different character heights and numbers of digits.

Change of the Controlling Protocol!

The displays use a new controlling protocol.
Due to the advanced possibilities, we recommend the use of this new option.

By default, the displays are already set to this new universal protocol.

For compatibility reasons, however, the “old” controlling can be activated by

software (MKS).
For details, refer to chapter “Protocol Classic”.

3.3.1 Configuration

The configuration of the Profibus interface normally happens using the
GSD file. It is initially imported into the "Device Catalog" of the configura­tion software. Subsequently, the Profibus interface can be “dragged” into
the bus system and then be configured.

With the configuration, the user can individually adapt data width within the data
transfer. Data widths of 1 to 16 bytes maximum are possible.
By specifying these identifiers in any order, the desired total data width is
set for both the input and the output data.

The maximum number of input and output bytes is 200 bytes each.
However a total number of 300 bytes (input + output) may not be exceeded.

 Default configuration: 2x 0x3F = 32 input and 32 output bytes

Attention:
The configured output data width must be at least 2 bytes larger than the longest

protocol to be sent (because of toggle and length byte).
The configured input data width must be at least 2 bytes larger than the longest

used response frame (because of toggle and length byte).

DP Diagnosis Data

The device does not support any extended diagnosis data. Default diag­nosis is utilised.

DP Parameter Data

The User_Prm_Data are not utilised by the interface. However, a test is run
to determine whether or not User_Prm_Data are transferred by the Profibus
master. If User_Prm_Data are transferred, Profibus initialisation is disabled
and the slave must be reconfigured and parameterised.

Note:
Standard parametrisation is required and is normally installed by the uti­lised DP configurators.

3.3.4 Operation

Start-Up Procedure:
As long as no Profibus connection is established, “----“ is shown.
After starting the Profibus connection, the minus signs (----) disappear

and the display waits for valid data.

DP Output Data

Control frames from the user must be entered into the DP output data.

In order to transmit a frame to the MIGAN, the bytes – described in chapter
“Control Data” - must be entered at the Profibus side as output bytes 3 through
n. After the length byte (= number of bytes of control data) has been entered,
the toggle byte must be changed in order to start transmission.

Before you send the next frame, the MIGAN must get enough time for processing
the current command!

It is strongly recommended to wait for the response frame of the MIGAN (see
chapter “Response Frame“).

DP Input Data

The user gets MIGAN response frames in the DP input data:

Each time a frame has been received from the MIGAN, it is entered as input
bytes 3 through n, and the frame length is entered as byte 2 (= length byte).
The length byte reflects the number of following bytes.
The toggle byte is also increased by 1.

3.4.1 Configuration of the Profinet Controller

The Profinet controller must be configured properly in order to communicate
with the Profinet device.

The following descriptions refer to the "HW Config" tool from Siemens and
are intended to represent the principle. This works of course with the tools of
other manufacturers.

First, the GSDML file (“GSDML-V2.2-microSYST-01CF-MifacePNIO-....xml“)

has to be added to the “device catalogue“ of the configuration tool (menu
item “Options/Install GSD File...“). Then, the interface is shown in the cata-

logue view as follows:

Now you can choose between 3 different “Device Access Points“:

- DAP1 (no PDEV),
if your Profinet controller does not know a “physical device“
(usually only with older Profinet controllers)

- DAP2 (standard, no MRP),

if the MRP ability of the interface shall not be activated.

- DAP3 (standard),

if the MRP ability of the interface shall be activated.

”Drag“ the needed “DAP“ to your Profinet system:

defined.

The output data width must be at least 2 bytes higher than the largest protocol,
that shall be sent (because of toggle and length byte).

The input data width must be at least 2 bytes higher than the largest protocol
(response frame) that shall be received; because of toggle and length byte.

There are Profinet IO modules with a data width of 1…250 bytes available:

Example: 40 bytes output, 16 bytes Input

Do not forget to define the I/O-addresses according to your needs!

We recommend to use for setting “Slot X1 / IO Cycle / Update time” not less

than 8 ms to avoid unnecessary network load)!
After finishing the Profinet configuration, it must still be loaded into the

Profinet controller:

- „Station/Save and Compile“

- „PLC/Download...“

3.4.2 Profinet Device: Assign Name

The Profinet device must be assigned (one time) the device name, which also
was chosen in the Profinet controller configuration ("miface1" in the example
above).

For this, connect the device to the Profinet network and connect its power sup­ply.

Start the tool for setting the device name:

o Mark(click) the concerned device in the bus overview
o Select the menu item “PLC/Ethernet/Assign Device Name...“
o Mark (click) the line with the corresponding device (see MAC-address)
o Click “Assign name“
o Close window

Tip: If you want to find the device of the marked line, you can click on „Flashing
on“. LED 1 (green) of the corresponding interface starts to blink then.

3.4.3 Interface Settings

The DIP switches are preset at delivery and must not be changed!

Default Settings:

*1: The interface ist mounted to the migan controller board.
*2: The interface is connected with the migan controller board via RS485.

3.4.4 Operation

Start-Up:
The connection between the Profinet controller and the Profinet device is

established automatically (this can last up to 10 seconds).
The red LED of the interface goes out, as soon as the Profinet connection
is established.
To let this happen, the PN controller must be correctly configured and the
PN device must have the matching name.

The communication between Profinet controller and the display (Profinet
device) happens within cyclic data traffic.

Profinet Output Data

The user must enter control frames into the Profinet output data.

In order to transmit a frame to the MIGAN, the frame bytes – described in
chapter “Control Data” - must be entered at the Profinet side as output bytes 3
through n. After the length byte (= number of bytes of control data) has been
entered, the toggle byte must be changed in order to start transmission.

Before you send the next frame, the MIGAN must get enough time for processing
the current command!

It is strongly recommended to wait for the response frame of the MIGAN (see
chapter „Response Frame“).

Profinet Input Data

Each time a frame has been received from the MIGAN, it is entered as input
bytes 3 through n, and the frame length is entered as byte 2 (= length byte). The
value of the length byte corresponds with the number of bytes of the response
frame.
The toggle byte is also increased by 1.

Thus only the toggle byte needs to be monitored at the Profinet control­ler side. As soon as it changes, data of the received frame can be read
out and next frame can be sent.

5.3 Maintenance and Care

Please observe the following instructions:

 Make sure that the housing can be opened for adjustment and mainte-

nance even after the display has been installed. Allow for adequate clear­ance at the back, front and top of the display unit in order to follow for suffi­cient ventilation (if vent slots are included).

 Display quality is impaired by direct illumination with bright light sources

and/or direct sunlight.

 The display must be switched off before cleaning.
 Protect the display from excessive humidity, extreme vibration, direct sun-

light and extreme temperatures. Non-observance may lead to malfunction­ing or destruction of the device. Under certain circumstances electrical
shock, fire and explosion may occur as well. Information concerning allowa­ble ambient conditions, including recommended temperature ranges, can
be found in the chapter entitled „Technical Data“.

 The display may not be placed into service if the device and/or the power

cable are known to be damaged.

 Do not attempt to repair the device yourself. The guarantee is rendered null

and void if the device is tampered with by unauthorized persons.

5.5 Warranty / Liability

For the product, liability is assumed for defects, which existed at the delivery
date according to our General Terms and Conditions.

Technically changes as well as errors are excepted. A claim for delivery of a
new product does not exist. The buyer has to check the received product imme­diately and indicate evident defects at the latest 24 hours after detection. Non­observance of notification requirements is equated with acceptance of the de­fect. Not immediately visible defects have to be indicated immediately after their
perception too.

Generally, defects and their symptoms must be described as accurately as pos­sible in order to allow for reproducibility and elimination. The buyer must provide
for access to the relevant device and all required and/or useful information at no
charge and must make all of the required data and machine time available free
of charge.

The guarantee does not cover defects, which result from non-observance of the
prescribed conditions of use, or from improper handling.

If the device has been placed at the disposal of the buyer for test purposes and
has been purchased subsequent to such testing, both parties agree that the

product is to be considered “used” and that it has been purchased “as is”. No

guarantee claims may be made in such cases.
The General Terms and Conditions of microSYST Systemelectronic GmbH in

current version apply as well.
