5.2. Embedded DeviceNet Master IO Map

5.2. Embedded DeviceNet Master IO Map​

 

One of each FN object will be assigned by the nodes, connected to the embedded DeviceNet master, and the FN object will be configured by 128 bit. IO will be mapped to the FNn object for node number *n* (*n *= 1–63) slave.

 

l  FNn.X1–128: node number *n* input data of slave (Hi5a controller ç slave)

l  FNn.Y1–128: node number *n* output data of slave (Hi5a controller è slave)

When the slave (node number *n*) that has input or output data that exceeds 128 bit is connected, the FX object of the next slave node (node number *n*+1) will be occupied. In this case, the DeviceNet communication of the next slave will not be connected to the Hi5a embedded DeviceNet master.

 

For example, when the output of node no. 3 is 136 bit, then slave no. 3 will occupy FN3, FN4. Therefore, it cannot be connected to the embedded DeviceNet master of the Hi5a controller even if slave no. 4 is physically connected to the DeviceNet.
