9pol. Sub-D Female Connector “ModbusRTU”
Remark: Depending on DIP5 of the ModbusRTU-interface (see below) either the RS232-pins or the RS485-pins may be used. The unused pins have to be left open. Do not use a standard RS232-cable where all pins are connected. Otherwise the ModbusRTU-interface may be destroyed!!!
9pol. Sub-D Male Connector “Configuration, RS232”
Remark: This connector should not be used by the customer! The configuration is al­ready done by microSYST and must not be changed! Otherwise the correct function of the display can not be guaranteed!
7pol. Mains Plug (230 VAC) or 3pol. Circular Plug (24 VDC)

Important note:
To change the setting of the DIP-switches obey the following order:
Disconnect the power supply.  Open the housing.  Set the dip switches as desired.  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!

Large Display Numeric LED with Modbus RTU Interface
4 ModbusRTU Interface
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 reg-
isters. Therefore the commands “Force Multiple Registers” (function code
16d=10 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! ModbusRTU output data must be entered as follows:
) or “Read/Write Registers” (function code 23
H
=17H) can be used.
d
The length byte and the control frame (see next chapter) must be entered first. Then, the trigger byte must be increased by one.
Thereby, the entered frame is transmitted to the MIGAN.

5.2 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 allow 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 Information”.
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 unauthorised persons.

5.4 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 accepted. 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. Non-observance 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.
