Thank you for purchasing the CX2000. This operation guide briefly explains the main operations related to the loop control function of the CX2000. For information about all the functions excluding the communication functions, installation and wiring procedures, operating procedures, and handling precautions of the CX2000, see the electronic manual CX2000 User’s Manual (IM 04L31A01-01E) provided on the accompanying CDROM.
Introduction to Control Functions For further details on each function, see chapter 1, “Explanation of Functions” in the CX2000 User’s Manual (IM 04L31A01-01E) provided on the accompanying CD-ROM. Control Types Control Mode The following four control modes are available (three types of control plus analog retransmission) and can be set for each control loop. The mode can be specified for each control output terminal block (two loops per block, see page 7).
Introduction to Control Functions PID Parameter Selection Method You can select the method for switching PID parameters from the following: • Target setpoint selection: By specifying the SP number. • Zone PID selection: By dividing the measurement span in to multiple zones and determining in which zone the PV resides. • Segment PID selection: Using the program pattern segment when in program control.
Introduction to Control Functions Preset Output This function sets the control output to the preset value when the operation is stopped. SP Ramp-Down-Rate/SP Ramp-Up-Rate This function is used to decrease or increase the setpoint at a constant rate of change (as opposed to a rapid change) when the SP is changed. Target Setpoint Limit This function is used to limit the range of values that the SP can change.
Wiring Input/Output terminals are arranged on the rear panel of the CX2000 as shown in the figure below. The figure shows the case when option terminals are specified on the model with 6 internal control loops and 20 measurement channels (CX2620). For the wiring procedure of the control/measurement input/output, see chapter 2, “Installation and Wiring” in the CX2000 User’s Manual (IM 04L31A01-01E) or the CX2000 Installation and Connection Guide (IM 04L31A01-71E).
Overview of Operations Key Operation For details on the key operation, see chapter 3, “Names of Parts, Display Modes, and Common Operations” in the CX2000 User’s Manual (IM 04L31A01-01E).
Overview of Operations Control Operation Display In operation mode, the following control operation displays can be selected. • Control group display This display is used to monitor the control status of multiple loops simultaneously including external loops. You can select from three display styles as shown in the display example in the figure below.
