The Function Block ARC_MAP provides information about the ARCNET network map. The output MAP shows the status of every node. If the node is active, a “1” is shown at the corresponding output array. (Each possible node has an own byte at the array; e. g. Nodes 2 and 3 are active -> array of Byte [2] = 1 and array of byte [3] = 1, the others have the value 0).
Every node of the ARCNET map is checked by the RTS for about 210 ms. So the complete cycle time for the whole map takes about 255*210 ms (If the map consists of 255 nodes. If the network consists of 5 nodes it takes about 1s).
