1 Installation of the Modbus communication card
Switch the power off before installing the Modbus card. Remove the plugs covering the screws on the controller enclosure.
Detach the covers from the enclosure, first the cover for the screw terminals (top) and then the larger cover (bottom).
Carefully rotate the lower cover 90 degrees so that the PCB at the bottom of the enclosure is visible. The controller display
unit fitted to the bottom cover is connected by flat cable to the PCB. Do not leave the bottom cover to hang from the flat
cable.
There is a microcircuit on a socket on close to the right edge of the PCB. The microcircuit code (N16 – EH-105 controller), is
printed on the PCB next to the microcircuit. Carefully detach the microcircuit from the socket.
Install the two plastic stand-offs that come with the Modbus card into the holes on the PCB. Align the Modbus card so that
the double row pin connector goes to the empty socket N16 and the plastic stand-offs on the main PCB fit into the holes in
the Modbus card. Press the Modbus card carefully into the place so that the pins go into the socket and the stand-offs will be
locked.
To use the Modbus interface, the DIP switches on the Modbus card must be configured correctly. The DIP switches can be
configured during the installation when the bottom cover is unattached or later with the covers in place. The display unit must
be detached from the bottom cover in order to configure DIP switches after refitting the bottom cover. The DIP switches are
then visible through the display unit opening and their position can be changed.
General communication parameters:
- Databits: 8
- Stop-bits: 1
- Paritity: No paritity
2 Installation of Modbus 100-DIN unit to the EH-105
Modbus-100-DIN must be installed to the
DIN rail next the EH-105. See the wiring
instructions page 4.
3 MODBUS-100 card and MODBUS-100-DIN DIP switches configuration
The DIP switch allows to configure the Modbus Device Address (1-247), the communication speed (4800, 960, 19200 or
38400 bits/s) and the biasing resistors for the bus.
3.1 MODBUS-100 card, device address (DIP 5-12)
Each Modbus Device must have unique Device Address in the Modbus network. Allowed addresses are 1 to 247. The
Device Address is configured by DIP switches 5-12. DIP switch 5 is the least significant bit and DIP switch 12 is the most
significant.
DIP switch position, 1 = ON Address
DIP 5 DIP 12

3.2 MODBUS-100-DIN, device address (5-9)
Each Modbus Device must have unique Device Address in the Modbus network. Allowed addresses are 1 to 31. The Device
Address is configured by DIP switches 5-9. DIP switch 5 is the least significant bit and DIP switch 9 is the most significant.

3.3 Setting up biasing resistors (DIP 1-2)
The Modbus-100 card and Modbus-100-DIN uses galvanically isolated RS-485 driver. Only one device at a time can write
into the network, while other devices are listening. For this reason there are situations when no device writes into the
network but all of them are listening. The biasing resistors ensure that the network reamains stable in this situation. This is
especially important if the network is long and if there is external interference.
Biasing resistor must be taken into use in two (and only two) devices per network, one at each end of the network. The
biasing resistors are taken into use using the Modbus-100 card’s or Modbus-100-DIN adapters DIP switches 1-2 as follows:
DIP1 DIP2
0 0 Biasing resistors are not in use
1 1 Biasing resistors are in use
3.4 Communication speed
The communication speed must be configured to be same for all of the devices on the same Modbus bus. The
communications speed is configured via bit switches 3-4 as follows:
:DIP4 DIP3 Speed
0 0 4800
0 1 9600
1 0 19200
1 1 38400
4 Modbus network cabling
A shielded twisted pair cabling is used for networking e.g. Belden 8762 or Datajamak 2x(2+1)x0.24. The network must be
wired as a daisy-chain, the cable going from one device to the next and there must not be any stubs (max. length of stub 0.5
m). The maximum length of the whole network is 1200m. 120 Ohm terminating resistors are connected to the both ends
of the network.
The protective shield of the twisted pair cable can be connected if needed in to protective earth in order to eliminate
interference. The connection is made only on one end of the protective shield.

Data in the EH-100 controllers Modbus registers is arranged so that information in the same context is in consecutive
registers. This makes it easier to read data from the Modbus network. The information is arranged as follows:

6 Using Modbus registers
When the controller starts up the Modbus card updates the contents of its registers from the controller so it does not answer
questions. Updating of the registers takes about 13 seconds. EH-105 controllers have as a standard a local user interface
from which settings can be adjusted. For this reason, there is a risk that the data in monitoring program (PC) is not up-to-
date with the actual controller data.
To prevent this from occurring, registers that contain the controller's setting type variables are divided into categories N1-N7.
If a setting is changed locally, this information is sent to register 81, bits 9-15. By monitoring bits 9-15 in register 81, the
monitoring program knows if the settings have been changed locally and can update the settings on the PC end. The
register's categories are listed in appendix 1. After updating, the front-end can reset register 81's bits 9-15 by writing the
value OxFE in register 98. Register 400 shows whether updating between the controller and Modbus card of
registers belonging to categories N1-N7 is occuring. If the value of register 400 is 0xFF, updating is occuring and an
application with a Modbus interface should not read category N1-N7 registers but waits for the value of register 400 to return
to zero.
When controllers time programs are manipulated from the local user interface (changed or just checked) and after that when
the user exits, the controller rearranges the time programs. For this reason the time programs states may no longer be in the
same Modbus registers that they originally were in. Nevertheless the controller always sets category bit N1 (time programs),
so the PC must always read the time programs again when this bit has been set. Empty spaces cannot be left in the time
program registers, but they must be filled in order.
Alarms are coded as bit data in registers 90-95. Alarm index is listed in Appendix 2. Bit data is saved during power failures
so it is always up-to-date. The alarm is acknowledged by writing active alarm index number to the register 98. This will
silence the alarm buzzer, but the alarm is still displayed in registers 90-95 until the alarm situation is normalized.
7 Special registers
7.1 Window registers
The EH-100 controller Modbus interface makes it possible to inspect and change the entire register space in 16 register
packages. This means that only 17 registers are needed to manage one controller, e.g., in a monitor application. To do this
use registers 500 – 516. Enter the address of the first register of the window you want to examine into register 500. Then
this address and the following 15 register values can be read from registers 501 – 516.
Example: Read registers 111 – 126 using window registers.
1. Enter number 111 into (register 1. of the window register) register 500.
2. After this register 111-126 values can be processed through registers 501 – 516.
7.2 Mirrow registers
The EH-100 controller modbus interface has setting registers whose upper and lower bits have different settings. For
example, when changing a lower bit setting, you must be careful that you do not accidently change the upper bit setting. In
addition, the above mentioned procedure may cause problems with some monitoring programs.
To minimize this problem, MODBUS – 100 the interface have so called mirror registers. The same Modbus operations (read
and write) that are carried out with the standard registers can be carried out with the mirror registers. Their register
addresses and content are as follows:
- 2000 – 2354: register’s upper bits 0 – 354 (MSB)
- 4000 – 4354: register’s lower bits 0 – 354 (LSB)
- 6000 – 6709: the original register is divided into MSB:s and LSB:s as follows:
o 6000 = 0 MSB, 6001 = 0 LSB, 6002 = 1 MSB, 6003 = 2 LSB…6708=354 MSB, 6709 = 354 LSB

Sum alarm
Bit 0 = A-sum alarm
Bit 1 = B-sum alarm
Function: If an alarm belonging to an alarm class is active
the bit state is 1, otherwise it is 0. If the bit state is
already 1 when a new alarm occurs, it goes to 0 for about
20 sec. and then it returns to its original state.
