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

Communication Protocols

Using the XP 3000 Command Set

Error Codes and Query Status

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)

RS-232/

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.
