Section 3. Overview

Advantages of PakBus:
•
Simultaneous communication between the CR200(X) and other devices.
•
Peer-to-peer communication-no PC required.
•
Other PakBus dataloggers can be used as "sensors" to consolidate all data
into one CR200(X).
•
Routing - the CR200(X) cannot act as a router, passing on messages
intended for another logger, but other dataloggers can. PakBus supports
automatic route detection and selection.
•
Datalogger to datalogger communications-special CRBASIC instructions
simplify transferring data between dataloggers for distributed decision
making or control.
•
In a PakBus network, each datalogger is set to a unique address before
being installed in the network. Default PakBus address is 1. To
communicate with the CR200(X), the datalogger support software (see
Telecommunications and Data Retrieval
(p. 131)) must know the
CR200(X)'s PakBus address. The PakBus address is changed using the
DevConfig software, CR200(X) status table, or PakBus Graph software.

See
Modbus
(p. 139).
The CR200(X) supports Modbus Master and Modbus Slave communication for
inclusion in Modbus SCADA networks.

See Care and Maintenance.
With reasonable care, the CR200(X) should give many years of reliable service.
3.1.8.1
Protection from Water
The CR200(X) and most of its peripherals must be protected from moisture.
Moisture in the electronics will seriously damage, and probably render un-
repairable, the CR200(X). Water can come from flooding or sprinkler irrigation,
but most often comes as condensation. In most cases, protecting from water is as
easy as placing the CR200(X) in a weather tight enclosure with desiccant and
elevating the enclosure above the ground. The CR200(X) is shipped with
desiccant to reduce humidity. Desiccant should be changed periodically. Do not
completely seal the enclosure if lead acid batteries are present; hydrogen gas
generated by the batteries may build up to an explosive concentration. Refer to
APPENDIX. Enclosures
(Appendix p. 31) for information on available weather
tight enclosures.
