Product Features
The PPC-2000 (PPC) offers high performance closed-loop (PID)
control and the ability to manipulate process control
algorithms and sequential logic in a very user friendly way. It
is a modular programmable process control system that utilizes
plug-in modules to meet different system requirements. The
controller can be configured for as many as 48 channels of PID
control and supports up to 288 programmable digital I/O
points. A motor interface module allows for operating up to 16
motor speed control systems. Seven types of hardware modules
are supported by the PPC system.
AnaWin3 HMI software is
used for configuration, operation and data acquisition.
LogicPro software is available as an option and can be used to
write logic programs for sequential and process control.
The PPC controller includes the following features:
• Multiple channels of closed-loop control and
programmable logic in an integrated package
• User-programmable, advanced control algorithms
• Modular hardware
• Bus expansion up to 9 additional modules
• Serial communication
• AnaWin3 operator interface compatible (single or multiple
PPC modbus network capability
• Analog inputs (as many as 128) per PPC system
• Multiple sensor inputs: multiple TC types, RTD, voltage,
current
• As many as 288 digital I/O points
• 48 closed-loop control channels with autotune
• Windows ® -based logic programming software (option)
• Third-party operator interface terminal (OIT) support
(option)
System Components
Any system must include a power supply and a processor
module (PPC-2010) with built-in digital I/O. The appropriate
additional modules are added for analog inputs, analog
outputs, and expanding the digital I/O.
See Figure 1.1 on page 6-4 and Figure 1.2 on page 6-6 for
illustrations of the PPC’s system components and modules.
Refer to
Table 1.1 on page 5 for a description of the modules and
their functions.
The number and types of I/O are determined by which modules
are selected for the application. Field wiring connects to DIN
rail or panel mounted terminal block boards. Terminal block
boards connect to I/O modules via 50-pin SCSI cables.
