CP-30: High Performance Processor Module
4.4.1 Overview
•
Compliant with IEC-61131 programming languages
•
Up to 3 communications ports
•
Supports Communications and Processor Redundancy
The CP-30 is a high performance processor module that can provide exceptional speed,
memory and functionality to your RTU.
Targeting large RTU systems, the CP-30 is equipped with a 166 MHz ARM9 CPU, capable
of running all IEC-61131-3 certified languages, and utilises an Ethernet port as the default
connection and configuration medium.
To configure the CP-30, a PC with an Ethernet port and the Toolbox PLUS+ software is
required.
Toolbox PLUS+ features ISaGRAF™ software, which provides logic programming in the
IEC-61131 standard languages: Structured Text, Ladder Diagram, Function Block Diagram,
Instruction List, Sequential Function Chart and Flow Chart.
The processor module has up to three independent communications ports. Ports 2 and 3
can use plug-in
while port 1 is fixed as Ethernet (both 10 Mbps and 100 Mbps
modes are supported).
RTUs can use a second CP-30 module to provide processor redundancy. One processor
must be installed in an even-numbered backplane slot (the active processor on power up)
and the other in an odd-numbered backplane slot (the passive processor on power up). The
active processor continuously scans all backplane slots (among other tasks) so that it can
detect, control and monitor all other RTU modules. The passive (standby) processor will
switch to active mode when it detects that communications on the backplane stopped for
longer than a predefined maximum time that may be caused (but not limited to) by:
•
Failure, removal or reset of the active processor
•
Download of the configuration, logic or firmware to the active processor
The CP-30 flash memory is used for the storage of all operating code, RTU configuration
and event logs. It also has 32 MB (v1.x) / 64 MB (v2.x) of SDRAM for program operation and
general data storage and 128 KB (v1.x) / 512 KB (v2.x) of battery backed SRAM for non-
volatile data such as retained variables and system log.
The module is powered from the +5 V
DC
rail on the backplane.
4.4.2 CP-30 Options and Ordering Info
Unless explicitly noted, all hardware versions of CP-30 modules are described in this
manual. The newer CP-30 version (v2.3) has some differences in the module features and
specifications comparing with its predecessor (v1.6); in particular the amount of battery
backed SRAM has increased from 128 KB to 512 KB, a quick reset to factory defaults has
been added, the backup battery has been made user replaceable, and the operating
temperature range has been extended to -40 °C to +85 °C.
CP-30 options, ordering info and main specification differences are summarised in the table
