1. A method for routing messages over a network of interconnected devices of a networked control system, wherein the devices are arranged in an approximately rectangular grid and each device is adapted for routing messages, which were received from directly neighbored devices in the grid, to directly neighbored devices in the grid, wherein the routing comprises the acts of: determining a routing path for a message from a sender device to a destination device through the grid (S routing the message from the sender device to the destination device along the determined routing path through the grid (S changing the routing path according to a predetermined routing rule for routing the message around a faulty device contained in the determined routing path (S a) selecting a changed routing direction of the routing path according to the predetermined routing rule, b) checking a connection link to the next neighbored device in the changed routing direction and c) if the connection link is working sending the message to the next neighbored device in the changed routing direction else repeating steps a)-c).
