Input/Output loop debugging (1) Analog input (AI) loop debugging. To carefully check the address allocation

of 10 modules: check whether the loop power supply mode (internal power supply or external power supply)

is consistent with the field instrument: Use the signal generator at the field end to add a signal to each channe

l, usually take 0, 50% or 100% point for inspection. For the AI loop with alarm and interlock value, it is also nec

essary to check the alarm interlock value (such as high, low and interlock points and accuracy) to confirm the co

rrectness of the alarm and interlock state. (2) Analog output (AO) loop debugging. According to the requirements

of loop control, the actuator (such as valve opening, etc.) can be checked by manual output (that is, directly set in t

he control system), usually 0, 50% or 100% three points for inspection; At the same time, through closed-loop cont

rol, check whether the output meets the relevant requirements, the AO loop with alarm and interlock value, but als

o check the alarm interlock value (such as high, low and interlock point and accuracy), and confirm the correctness

of the alarm and interlock state. (3) Switching input (DI) circuit debugging. Short-circuit or disconnect at the corresp

onding field end, check the change of the light emitting diode corresponding to the channel address of the switchin

g input module, and check the change of the channel on and off. (4) Switching output (DO) loop debugging. The outp

ut points can be checked through the forced function provided by the PLC system. By force, check the change of the

light emitting diode corresponding to the channel address of the switching quantity output module, and check the ch

ange of the channel on and off.

Cloud dynamic control card is the backbone PC bus, with high performance external processor (DSP and large-scale programmable devices to achieve multi-axis coordinated control of multi-person service motor A high performance into/with the service machine motion control card, including pulse output, pulse counting, digital input, digital output, D/A output and other functions, it can emit continuous, high frequency pulse train, By changing the frequency of the pulse to control the speed of the motor, changing the number of pulses to control the position of the motor, its pulse output mode includes pulse/direction, pulse/pulse mode. The pulse count can be used to reflect the position of the encoder, provide accurate position of the machine, correct errors generated during transmission, digital input/output points can be used for limits, origin switches, etc. The library functions include S-type, T-type acceleration, linear and circular interpolation, multi-axis linkage functions, etc. Products are widely used in the field of industrial automation control need to determine the position control system, fixed length position control system and PC-based NC control system. Specifically, the underlying software and hardware of motion control are integrated together, so that it has various speed and position control functions of the same motor control, which can be easily invoked by the computer. In a motion control system, the motion control card is the core module of the control system, which is also the most closely related to the design purpose of the control system. When the motion control card is fixed, the other designs must be selected and designed around the dirty motion control, so how to choose the motion control card is very important to the design of the motion control system.
