Serial Communications Unit's unit address (Unit
address as CPU Bus Unit)
12 hex = Unit 10 hex
Serial port number
1: Port 1
Note:
The serial port's unit address can be specified directly by setting the serial port number to 0 and
setting the Serial Communications Unit's unit address to the serial port's unit address.
(Set the unit address to 80 hex + 4 x unit number for port 1 or 81 hex + 4 x unit number for port 2.)
Port number specifier
3: Logical port 3
Serial Communications Unit's unit address
88 hex = 80 hex + 4 x unit number
Serial port number
0: Specify port directly.
Port number specifier
3: Logical port 3
Data sent.
In this example, a start and end code have been
specified in the allocated DM Setup Area.
ST: Start code (e.g., 02 hex)
ED: End code (e.g., 03 hex)
Most signifi-
cant bytes
Least signif-
icant bytes
