Software Communication
This chapter describes how to communicate with the XP 3000: through an
RS-232, RS-485, or CAN (Controller Area Network) interface, depending on the pump
configuration.
This chapter includes these topics:
XP 3000 Addressing Scheme
As part of the communication protocol, an address for each pump must be specified. The
user has the option of addressing a single pump, two pumps (dual device), four pumps
(quad device), or all 15 pumps (all devices), depending on the address byte used. Each
physical address in the address switch corresponds to a hexadecimal value, as shown in
Table 3-1.
Table 3-1. Hexadecimal Addressing Scheme
Address (hex)
Device
RS-232/
RS-485
CAN
30
0
Master Address (master controller, personal computer, etc.)
31..3F
1..F
Addresses single device
41..50
11..20
Addresses two devices at a time (dual device)
51..5D
21..2D
Addressed four devices at a time (quad device)
5F
2F
Addresses all devices on the bus
For example, an XP 3000 with address switch set to 0 is addressed as device “31h” in the
RS-232 or RS-485 communication protocol, hardware address 1 is addressed as device
“32h,” and so on.
Table 3-2 shows the different address switch settings for each of these configurations.
