Read More! See section PakBus Overview (p. 334) for more information. Also see
Campbell Scientific PakBus® Networking Guide available at
www.campbellsci.com.
PakBus
®
is a proprietary network communications protocol designed to maximize
synergies between Campbell Scientific dataloggers and peripherals. It features
auto-discovery and self-healing. Following is a list of CRBasic instructions that
control PakBus
®
processes. Each instruction specifies a PakBus
®
address and a
COM port. The PakBus
®
address is a variable that can be used in CRBasic like
any other variable. The COM port sets a default communications port when a
route to the remote node is not known. The following COM port arguments are
available:
• ComRS-232
• ComME
