Slot_ID

If a Modbus Plus network option module (NOM) in the rack of a Quantum controller is addressed as the destination node, the value at the Slot_ID input represents the physical NOM slot, i.e. if the NOM is plugged in at Slot 7 of the rack, the value appears as follows:

Routing x

The Routing x input is used for address specification (routing path addresses one of five) of the destination node during network transfer. The last byte in the routing path that is not zero is the destination node.

Routing Tab 1

If a Modbus Plus Network Options Module (NOM) is addressed as the destination node in a Quantum control module rack, the most significant byte represents the physical slot of the NOM. If the destination node is a CPU, the most significant byte (regardless of the CPU slot) is set to "0".

If NOM is inserted in slot 7 on the module rack, the most significant byte of routing tab 1 looks as follows:

Most significant byte Slots 1 ... 16

Least significant byte Destination address (binary value between 1 and 64 (normal) or 65 to 255 (extended))
