DALI WITH A MODICON FIPIO BACKBONE APPLICATION SOLUTION REQUEST FOR A CRUISE SHIP

Hi,

We have encountered a very old system inside a cruise ship which has a Schneider Modicon FIP IO backbone inside.

Now, the owners want to replace the lighting system with DALI , but they don’t want to change any cabling and they want to use the old FIP IO backbone.

So, my question is , have you ever come accross this bus backbone before? If yes, how we can adapt the old system with our DALI and PFC100/PFC200 solution.

I have searched and find an Anybus Communicator from HMS, which is a serial master to FIP IO system. But, even if we use this serial master to FIP IO communicator, how should we handle the DALI cabling too?

I would like to ask our Norwegian colleauges or marine users, have you ever come accross with this FIPIO backbone before and how could you integrate it into our own controller system with a DALI master module?

Regards,

Basak

Hello, are those with the shielded coaxial cable as backbone ?
DALI can use any cable as long as the maximum voltage drop is 2V:
0.50 mm2 (20 AWG) for up to 100m.
0.75 mm2 (18 AWG) for up to 150m.
1.50 mm2 (15 AWG) for up to 300m.
(If you go over 300m you have to use repeaters but those aren’t generally DALI certified).
Free wiring topology is allowed (star, tree, or bus). Rings or closed loops must be avoided.

Hi,

Thank you for the suggestion but the problem is, the end user does not want to make any new cabling for DALI lines because it is a 250 meter long cruise ship and it is already scheduled for Carribean tours for next 3 years, no time to make a new cabling that is why they ask if there is a way to communicate over FIPIO backbone.

So, we are going to use an ON-OFF system instead of DALI and we are going to use FIPIO to Modbus TCP Gateway.

I think this is the most practical solution, If the cabling propriety aren’t known using DALI could result is the lighting not working properly.
