The example above is a ControlLogix message instruction to read the
user-configured table, assembly instance 37.
Because the floating-point word order in the
TIP
ControlLogix controller is reversed from that in the
Powermonitor 3000, your ladder logic will need to
reverse the word order so the data may be
interpreted correctly. The SWPB instruction performs
this function.
Up to four concurrent explicit messaging connections are supported
by the DeviceNet communications port.
