Set-up procedure

1. Install Intesis MAPS on your laptop, use the setup program supplied for this and follow the instructions given by

the Installation wizard.

2. Install Intesis in the desired installation site. Installation can be on DIN rail or on a stable not vibrating surface

(DIN rail mounted inside a metallic industrial cabinet connected to ground is recommended).

3. Connect the M-Bus communication cable coming from the M-Bus network to the port marked as Port A on Intesis

(More details in section 4).

4. If using, Modbus RTU, connect the communication cable coming from the EIA485/EIA232 port of the Modbus

RTU installation to the port marked as Port B of Intesis (More details in section 4).

If using, Modbus TCP, connect the communication cable coming from the Ethernet port of the Modbus TCP

installation to the port marked as Port B of Intesis (More details in section 4).

5. Power up Intesis. The supply voltage should be any of the voltage range allowed (check section 6). Take care of

the polarity of the supply voltage applied.

WARNING! In order to avoid earth loops that can damage Intesis and/or any other equipment connected to

it, we strongly recommend the use of DC power supplies, floating or with the negative terminal connected to

earth. Never use a DC power supply with the positive terminal connected to earth.

6. If you want to connect using IP, connect the Ethernet cable from the laptop PC to the port marked as Ethernet of

Intesis (More details in section 0).

If you want to connect using USB, connect the USB cable from the laptop PC to the port marked as Console of

Intesis (More details in section 0).

7. Open Intesis MAPS, create a new project selecting a copy of the one named INMBSMEB---0000.

8. Modify the configuration as desired, save it and download the configuration file to Intesis as explained in the

Intesis MAPS user manual.

9. Visit the Diagnostic section and check that there is communication activity, some TX frames and some other RX

frames. This means that the communication with the M-Bus installation and Modbus Master devices are OK. In

case there is no communication activity between Intesis and the M-Bus and/or Modbus devices, check that those

are operative: check the baud rate, the communication cable used to connect all devices and any other

communication parameter.
