3.1.4.5  
  Network Query and Control Functions 
 
A special subset of three (3) UDP/IP commands may be sent to a module at any time power is 
applied to it (i.e., neither a host socket connection nor a unique IP Address assignment is 
required).  Each such command is broadcast to all modules (i.e., sent to IP Address 
255.255.255.255) via Port 7000, and any module wishing to respond will return a UDP/IP 
broadcast response via Port 7001. 
 
Only one of these commands returns a response.  This is the Network Query (“psi9000”) 
command.  The others cause the module to be re-booted, therefore no response is possible.  
One command changes the way the module gets its IP address assignment (i.e., dynamically 
from a server or statically from factory-set internal data). 
 
3.1.4.6  
  Other Functions 
 
Some commands may be used at any time to obtain information about the internal setup and 
status of a module. The Read Module Status (‘q’) command is an example. Also, the Set/Do 
Operating Options 
(‘w’) command, though generally used after power-up reset, may also be 
used at other times to change system operation. The actual feedback position status of internal 
valves, and several temperature status conditions may be configured to be periodically 
delivered to the host automatically in any of the three autonomous streams configured by the ‘c’ 
command.
