7.1.1.2 Datalogger-to-Datalogger Communication
Communication between dataloggers is possible over TCP/IP. In order to do
this, a socket must be opened between the two dataloggers using the
TCPOpen()
instruction or using the
PakBus/TCP Client
setting. Note that
only one datalogger should be set up to open the connection. The socket
opened by the
TCPOpen()
instruction or the
PakBus/TCP Client
setting is
used by the instructions performing datalogger-to-datalogger communication.
The example program below gets the battery voltage from a remote datalogger
and sends its panel temperature to the remote datalogger. The remote
datalogger is at IP address 192.168.7.125 and port 6785 is used for
communication between the dataloggers. The remote datalogger must have its
battery voltage stored in a public variable,
BattVolt
. It must also have a public
variable declared,
PTemp_Base
. This will be used to store the panel
temperature of the base datalogger.
