Note 1 Set the source network address in the routing tables unless you are specifying a local network. Set the source net-
work address to 00 for a local network. If there is more than one CPU Bus Unit mounted in the PLC, the “local net-
work” is the network of the CPU Bus Unit with the lowest unit number.
2 The unit addresses are as follows:
• CPU Unit: 00 hex
• CPU Bus Unit: 10 hex + unit number (hex)
• Special I/O Unit: 20 hex + unit number (hex) (Except for C200H Special I/O Units)
• Inner Board: E1 hex (CS Series only)
• Computer: 01 hex
• Unit connected to network: FE hex (Eliminates the need to specify the unit number of the remote Unit.)
The serial port unit address are as follows:
• Serial Communications Units:
Port 1: 80 hex + 04 hex × unit number
Port 2: 81 hex + 04 hex × unit number
• Serial Communications Boards:
Port 1: E4 hex (228 decimal)
Port 2: E5 hex (229 decimal)
• CPU Unit
Peripheral port: FD hex (253 decimal)
RS-232C port: FC hex (252 decimal)
3 Broadcasting is not possible for RECV2(492). Set 00 hex to request a reception from the local node.
