USE
IOMB-TCP/IP is a gateway for IOMB-02, IOMB-
03 and IOMB-04 that permits communication
with the I/O modules via TCP/IP.
FUNCTION
The TCP/IP gateway communicates inter-
nally with the I/O module via modbus RTU and
externally via TCP/IP. In order for the factory-
set Modbus communication to work, all DIP
switches On the I/O module must be set to
OFF. You can change the Modbus communica-
tion settings in the web interface for the TCP/
IP gateway, in which case you must also adjust
the DIP switch settings in the I/O module.
The TCP/IP gateway has the capacity to com-
municate with one external device (e.g. OPC
server) at a time.
MOUNTING
The IOMB-TCP/IP is mounted using the 4 screws
and washers provided, onto the I/O modules IOMB-
02, IOMB-03 or IOMB-04.
By replacing the rubber gasket in the M20 screw in
the I / O module with the supplied multi-hole gasket,
a pre-contacted Cat5 / 6 can be used. See Figure 1.
Remove the termination jumper located on the I / O
module. Please note that the 10-pin strip fits correct-
ly during the assembling. See Figure 2.
INSTALLATION
The DIP switches (1–10) in the I/O module must be
in their OFF positions to enable internal communica-
tion between the I/O module and the TCP/IP gateway.
Instruction, connection to network:
1. Connect the TCP/IP module to the designated
location on IOMB-02, IOMB-03 or IOMB-04.
2. Fit the 4 accompanying washers and screws.
3. Energise the I/O module. The green and yellow
LEDs on the TCP/IP module light up.
4. Press the button to the right of the yellow LED and
hold it down until the yellow LED flashes twice.
The TCP/IP gateway is now set to receive an IP
address via DHCP.
5. Plug in the network cable.
6. To access the network settings, open a web
browser and search for host name: ”http://calec-
trobrige”. If you experience problems locating the
TCP/IP gateway, download and install the pro-
gram: “Microchip TCPIP Discoverer” available-
from Calectro’s website: http://www.calectro.se/
products/#!/programvaror/. This program looks
for all connected gateways that have a TCP/IP
circuit from Microchip and displays their assigned
IP addresses.
7. Log in to network settings with the user name:
“admin” and password: “admin”.
8. Click NETWORK SETTINGS to access the net-
work settings.
9. Under MODBUS SETTINGS you can manage
internal communication between the I/O module
and the TCP/IP gateway. You do not usually need
to adjust this. The default settings in MODBUS
SETTINGS correspond to the I/O module’s DIP
switch in the OFF position.
MAINTENANCE
IOMB-TCP/IP is maintenance-free.
