Software Communication
This chapter describes how to communicate with the XLP 6000: through an
RS-232, RS-485, or CAN (Controller Area Network) interface.
This chapter includes these topics:
Using the XLP 6000 Command Set
3.1
XLP 6000 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, Hexadecimal Addressing Scheme.
Table 3-1
Hexadecimal Addressing Scheme
For example, an XLP 6000 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, Address Switch Settings in Hex (ASCII), shows the different address
switch settings for each of these configurations.
Note: When using the Pump:Link software to send commands to a device, use
the ASCII address values in Table 3-2.
