HANDLING OF PUMP BOOT REQUESTS
When the pump is first powered up or receives a system reset command (frame type,
command 0), the pump notifies the host of this condition by sending a boot request
message at 10 to 12 second intervals until it receives a proper response. The group
number is 1 for the boot request message. The frame type is 2 when the pump sends
messages to the host, and the frame type must be 0 when the host replies to the boot
request.
Example 1. The pump is set to address 0
Pump sends:
Dir Group Device Frame RTR Length
1 001 0000 010 0 0000
Host acknowledges:
Dir Group Device Frame RTR Length Node ID Slave ID
0 001 0000 000 0 0010 0010 0000 0010 0000
Host acknowledges the boot request with:
Dir = 0 Host to slave
Group = 1 Boot request response group
Device = 0 Always 0 in boot response
Note:
Boot MID is the same for all nodes
Frame = 0 Boot request response frame
Rtr = 0 Always 0
Length = 2 Two data bytes in return message
Node ID Group ID (2) + Pump
Address (0)
“ ” 00h Must respond with Group & Address
Slave ID Same as Node ID
(hex 20)
“ ” 00h
