PakBus Networking Guide

When should PakBus be used?

When adding to an existing system it may make sense to remain mixed-array,

especially if your network must include non-PakBus dataloggers such as the

21X, CR7, etc., or if you rely on storage modules. However, communication

equipment costs for PakBus systems are usually the same as for traditional

communication and, although, like any other change, it takes some time and

effort to learn the ins and outs of PakBus networking, the advantages are many.

Advantages of PakBus:

• Table based final data storage with more conventional strings for date/time

stamps.

• Datalogger instructions that are the same as array-based except for the new

P84 Data Table instruction and P190, P193 and a handful of associated

instructions for efficient ‘wireless sensor’ cluster communications.

• Concurrent communications.

9 allows keyboard display to access datalogger while connected.

9 allows two PCs access to a particular datalogger at the same time.

• Distributed, intelligent route management.

9 allows peer-to-peer communications (i.e., datalogger can easily

exchange Input Locations or variables with any other network

datalogger).

9 allows you to change communication routes remotely and let the

network relearn the routing on its own.

9 allows you to program automatic back-up routes.

3.1.2 Minimum PakBus Network

The simplest PakBus network consists of a PC running LoggerNet with a COM

port connecting via an SC32B to a PakBus datalogger.
