CONNECTION DIAGRAM
ENDA EUP1122 devices are intended for rail mounted installations. Make sure that the device is used only for intended purpose. The shielding must be
grounded on the instrument side. During an installation, all of the cables that are connected to the device must be free of electrical power. The device must
be protected against inadmissible humidity, vibrations, severe soiling. Make sure that the operation temperature is not exceeded. All input and output
lines that are not connected to the supply network must be laid out as shielded and twisted cables. These cables should not be close to the power cables
or components. The installation and electrical connections must be carried out by a qualified staff and must be according to the relevant locally applicable
regulations.

The logic output of the instrument is not electrically
insulated from the internal circuits. Therefore, when
using a grounded thermocouple, do not connect the
logic output terminals to the earth.
1) Mains supply cords shall meet the requirements of IEC 60227 or IEC 60245 .
2) In accordance with the safety regulations, the power supply switch shall bring
the identification of the relevant instrument and it should be easily accessible by
the operator.
See “1.9 Memory Map for
Input Registers” for details.

J-K-L-T-S-R Type Thermocouples :
Use the correct compensation cables for
thermocouples. Do not use jointed cables. Make sure to
connect to the right place and right polarities at the input
terminals as shown in the figure.
Resistance (PT100) Thermocouples :
Make short circuits 2 and 3 terminal lines for two-wire
PT100 sensors. Do not use jointed cables. Long cable

Default Set Settings. Default settings is performed
when all the DIP Switch positions are set to 0 (OFF).
When required to return to the factory values or to adjust the modbus
communication speed, at first, the DIP switch value should be adjusted according
to the numerical value corresponding to the operation in the adjacent table (Please
See Note1).
DIP switch value is set to required modbus address value and DIP switch is left in
this setting position (Please see Note2).
NOTE2 :
When setting the device address at first, the 8th switch should be turned off and
then the switch values from 1 to 7 of the address to be adjusted should be set.
If the 8th switch should be ON at the selected address, the 8th switch should be set
to ON at the end of the procedure finaly.

2. MODBUS ERROR MESSAGES
Modbus protocol has two types error, communication error and operating error. Reason of the communication error is data corruption in
transmission. Parity and CRC control should be done to prevent communication error. Receiver side checks parity and CRC of the data. If they are
wrong, the message will be ignored. If format of the data is true but function doesn’t perform for any reason, operating error occurs. EUP1122
realizes error and sends error message. Most significant bit of function is changed '1' to indicate error in error message by EUP1122. Error code is
sent in data section. EUP1122 realizes error type via this message.

The function code received in the query is not an allowable action for the EUP1122. If
a Poll Program Complete command was issued, this code indicates that no program
function preceded it.
The data address received in the query is not an allowable address for EUP1122.
A value contained in the query data field is not an allowable value for the EUP1122.

Error Code
Message sample ;
As you see in command message, coil information of (4A1)h = 1185 is required but there isn’t
any coil with 1185 address. Therefore error code with number (02) (Illegal Data Address) sends.
