Product Features:
control function
1.1 Control mode control function, pay attention to programmable mode and three pre designed control structure modes, and then decide which one to choose.
11.1. 1 Programmable Mode Programmable mode is a method of combining control modules and various computational modules through programming to determine the control structure. This mode can use basic control modules (BSC), cascade control modules (CSC), and selective control modules (SSC). Each control module is composed of control elements as the center, sets the control type and operation formula of the control elements, and determines the control mode.
1.1.2 Single loop control mode adds pre designed auxiliary control functions to the basic control module, and determines the control mode of the control structure based on the mode selection.
1.1.3 Cascade Control Mode: Pre designed auxiliary control functions are added to the cascade control module to determine the control mode of the control structure based on mode selection and execute cascade control.
1.1.4 Select control mode to perform automatic selection control of two control elements. Add pre designed auxiliary control functions to the selection of control modes, and determine the mode of the control structure based on the mode selection.

Sampling value PI control with nonlinear control function is a function in programming mode. The PI parameters are the same as the basic PID. Sampling period: 0-9999 seconds. Control time: 0-9999 seconds. It has non-linear control function. Batch PID belongs to the basic control module of programmable mode. The PID parameters are the same as the basic PID. Deviation: 0.0-100.0% Bias: 0.0-100.0% Lock width: 0.0-100.0%
1.3 Auxiliary control function
The auxiliary control function is pre attached to the function selection mode. In programmable mode, it can be freely constructed through programming. Feedforward control single loop mode and cascade mode functions. Add the feedforward signal operation value to the control output during cascade or automatic operation. Output tracking is a function within the single loop mode. During cascading or automatic operation, use status signals as trigger signals to track external signals in the operation output. During cascading or automatic operation, the preset MV output is used as the operational output through status signals. This function is available in all function selection modes. Pre set PID (only for programming mode) is set in the user program according to pre-defined PID parameters (8 sets).
1.4 Response characteristics of variable set value filtering adjustment when the set value is changed. Adjust with two parameters.
1.5 Self tuning (STC) is a function that automatically tracks changes in process characteristics and PID parameters. It can start or stop the self-tuning function based on the PF key and user program. The PID parameter self-tuning limit can be set. The basic control module that can be used in combination is the first circuit in single circuit mode and the designated circuit in programmable mode. The cascade control module is connected to the STC function through internal OPEN/CLOSE, and is the first circuit when CLOSE is applied; When OPEN, it is the second circuit. The selected control module is equipped with the selected circuit. Possible combinations of control types include basic PID control, nonlinear PID control, and PID control with reset bias
1.6 Alarm Function Alarm Function: Upper Limit, Lower Limit, Absolute Deviation Upper Limit Alarm Setting: -6.3~106.3% (or engineering unit) Lower Limit Alarm Setting: -6.3~106.3% (or engineering unit) Absolute Deviation Alarm Setting: 0.0~106.3% (or engineering unit) Delay Width: 2% Change Rate Alarm Change Rate Setting: 0.0~106.3% (or engineering unit) Change Time Setting: l~9999 seconds Alarm Display: The ALM light on the front panel is on (yellow). Display in the circuit screen and alarm screen (detailed display in the alarm screen). When the alarm is triggered, the contact can be disconnected or connected: the contact output during power outage can be set arbitrarily: the output contact for disconnection: the single circuit mode has one upper limit, one lower limit, and one deviation point each; Each control element of cascade control and selective control has upper limit, lower limit, and deviation alarm, with 1 output point each when an alarm occurs; In programmable mode, it is output by programming.
1.7 Input output signal operation function (function selection mode) Input signal operation function Small signal cut-off point variable square root operation performs square root operation on measurement inputs 1, 2 and external cascade setting inputs. The presence or absence of operations and the cutting point can be set. The setting range for the small signal cutoff point is 0.0 to 100%. Perform 10 line function operations on measurement inputs 1 and 2. The presence or absence of calculations and the set values for line output can be set. The range of line output setting is 0.0~100%, with an input interval of 10%. The first-order lag operation is applied to the measurement inputs 1 and 2, cascade setting inputs, tracking inputs, and feedforward inputs. The time constant is set within the range of 0.0 to 800.0 seconds. Whether the external cascade setting signal ratio operation can be set or not. Operation formula: CSV=CGN (CIN+CBI)+CBO CSV: Operation output CIN: Cascade input CGN: Gain (set range: -8.000~8.000) CBI: Input bias (set range: -106.3~106.3%) CBO: Output bias (set range: -800.0~800.0%) Feedforward signal operation with or without adjustable operation formula: FF=FGN (FIN+FBI)+FBO FF: Feedforward output FIN: Feedforward input FGN: Gain (set range: -8.000~8.000) FBI: Input bias (set range: -106.3~106.3%) FBO: Output bias (set range: -106.3~106.3%); -800.0~800.0%) Output signal calculation function output limit: The control outputs of each control module have
