ControlWave Express INTRODUCTION
1.1 GENERAL DESCRIPTION
ControlWave Express remote terminal units (RTU) have been designed to perform as the
ideal platform for remote site automation, measurement and data management in process
control and manufacturing. ControlWave Express RTUs measure temperature and monitor
a variety of analog and digital inputs. In addition to operation in a protected outdoor
environment (once mounted in a suitable enclosure), ControlWave Express RTUs provides
the following key features.
Hardware/Packaging Features:
• 32-bit ARM9 processor (LH7A400) provides exceptional performance and low power
consumption
• Wide operating temperature range: (-40 to +70°C) (-40 to 158°F)
• Two Board Platform: (CPU/System Controller Bd.
And optional Process I/O Bd.)
Three CPU/System Controller Board Configurations
: Standard I/O included on
CPU/System Controller Bd.: 2 Pulse Counter/Digital Inputs
• Ultra Low Power 14MHz CPU: Supports a nominal +6Vdc or a nominal +12Vdc
input power, Solar Regulator and an Auxiliary Power Output
• Low Power 33MHz CPU: Supports a nominal +12Vdc or a nominal +24Vdc input
power, Solar Regulator and an Auxiliary Power Output
• 33MHz CPU (with 10/100Base-T Ethernet Port): Supports a nominal +12Vdc or a
nominal +24Vdc input power, without Solar Reg. and without Aux. Power Output
Three Optional Process I/O Board Configurations
:
• 2 DI/DO, 4 DI, 2 DO & 2 HSC
• 2 DI/DO, 4 DI, 2 DO & 2 HSC, 3 AI
• 2 DI/DO, 4 DI, 2 DO & 2 HSC, 3 AI, 1 AO
• Battery backup for the real-time clock and the system’s SRAM is provided by a 3.0V,
300mA-hr lithium coin cell battery located on the CPU Module
• Very low power consumption - minimizes costs of solar panel/battery power systems
• Three serial communications ports (Two RS-232 and One RS-232/485)
• RTD Input (on 14MHz Ultra Low Power CPUs) (connection to a 100-ohm platinum bulb)
(using the DIN 43760 curve)
• Nonincendive Class I, Div. 2, Groups C & D Hazardous Locations (see Appendix A)
• Cost effective for small RTU/Process Controller applications
Firmware/Software Features
• Functions as a Process Controller or Remote Terminal Unit (RTU)
• Standard application programs will be introduced on a continual basis with WebBSI
Web pages that are preconfigured for all user operations.
• Using our ControlWave Designer IEC 61131-3 Programming Environment, any user or
third party can modify a standard application or create a completely customized
program.
• ControlWave Express RTUs are compatible with Bristol RTUs in software and
networking solutions for SCADA data editing/management, and are similar in all
operations.
ControlWave Express RTUs are comprised of a CPU/System Controller Board, an optional
Process I/O Board and a two piece enclosure (consisting of a card-edge cover and a
mounting chassis). Sharp’s LH7A400 System-on-Chip Advanced RISC Machine (ARM)
