DCP200 Profile Controller & Recorder - Product Manual

Serial Communications Configuration

A sub-menu of Configuration Mode used to adjust the serial communications parameters. (Addressing, data rate, parity, master/slave settings and write enabling).

Also refer to: Configuration Mode, Serial Communications

Serial Communications Option

A feature that allows other devices such as PC’s, PLC’s or a master controller to read, or change the instruments parameters via an RS485 or Ethernet network.

Full details can be found in the Serial Communications sections of this manual.

Also refer to: Ethernet, Master & Slave, Modbus RTU, Modbus TCP, PLC, RS485 and Serial Communications Configuration.

Setpoint

The target value at which the instrument attempts to maintain the process variable, by adjusting its control output power (the correcting variable). There can be either one or two setpoints. Local Setpoint 1 and/or an Alternative Setpoint. The Alternative Setpoint can be chosen from Local Setpoint 2 or a remote setpoint input from Auxiliary Input A or B if either of these is fitted. One setpoint can be chosen as active using the defined Setpoint Selection method. Setpoint values are limited by the Setpoint Upper Limit and Setpoint Lower Limits.

Also refer to: Alternative Setpoint, Auxiliary Input, Correcting Variable, Local Setpoints, Process Variable, Remote Setpoint, Scale Range Lower Limit, Setpoint Lower Limit, Setpoint Upper Limit and Setpoint Select

Setpoint Upper Limit

The maximum value allowed for setpoints. It should be set to keep the setpoint below a value that might cause damage to the process. The adjustment range is between Scale Range Upper Limit and the Setpoint Lower Limit. If the value is moved below the current value of a setpoint, that setpoint will automatically adjust to keep within bounds.

Settings = Within Input Span

Default Value = Scale Range Upper Limit

Also refer to: Input Span, Scale Range Upper Limit, Setpoint and Setpoint Lower Limit.

Setpoint Lower Limit

The minimum value allowed for setpoints. It should be set to keep the setpoint above a value that might cause damage to the process. The adjustment range is between the Setpoint Upper Limit and the Scale Range Lower Limit. If the value is moved above the current value a setpoint, that setpoint will automatically adjust to keep within bounds.

Settings = Within Input Span

Default Value = Scale Range Lower Limit

Also refer to: Input Span, Scale Range Lower Limit, Setpoint and Setpoint Upper Limit.

Setpoint Ramp Editing

Enables or disables the viewing and adjustment of the setpoint ramp rate in Operation Mode. This parameter does not disable the ramping SP feature; it merely removes it from Operation Mode. It can still be viewed and adjusted in the Control Configuration sub-menu. To turn off

ramping, the ramp rate must be set to OFF.

 

Settings = Enabled or Disabled

Default Value = Disabled

Also refer to: Control Configuration, Operation Mode, Process Variable, Setpoint and Setpoint Ramp Rate.
