II. Performance Parameters
Power Requirement: The working power of the module is provided by the backplane of the Series 90-30 PLC rack, usually +5V DC. The power consumption is low, which will not cause excessive burden on the power supply of the PLC system, ensuring stable output of the system power supply and providing reliable power support for the normal operation of the internal circuit of the module.
Number of Counting Channels: It has 2 independent pulse counting channels, which can collect and count 2 pulse signals at the same time, meeting the basic requirements of small and medium-sized industrial control systems for the number of pulse signal acquisitions, and can be flexibly applied to different control scenarios.
Counting Range: Each counting channel has a wide counting range, usually up to 0 to 4294967295 (32-bit unsigned integer), which can meet the range requirements for pulse counting in most industrial applications and is suitable for counting scenarios of long-term and large numbers of pulse signals.
Maximum Counting Frequency: It supports a relatively high counting frequency, usually up to 100kHz, which can quickly respond to high-frequency pulse signals, accurately capture changes in pulses, ensure accurate measurement of the position and speed of high-speed moving equipment, and is suitable for industrial control occasions with high requirements for counting speed.
(2) Interface Characteristics
Pulse Input Interface: Equipped with 2 independent pulse input interfaces, using screw terminal connection mode, the wiring is firm and reliable, and easy to install and maintain. The interface supports differential signal input, which can effectively resist external electromagnetic interference and ensure stable transmission of pulse signals. Each input interface has a clear identification corresponding to the corresponding channel number, which is convenient for technicians to perform wiring operations.
Backplane Interface: It communicates with the PLC processor through the rack backplane interface of the Series 90-30 PLC, and transmits the counting results to the PLC processor. The backplane interface adopts a reliable electrical connection design to ensure the timeliness and accuracy of data transmission, making the module and the PLC system form an organic whole to collaboratively complete pulse counting and control tasks.

(3) Environmental Adaptability
Operating Temperature: The operating temperature range of the module is 0°C to 60°C, which can adapt to the temperature environment of most industrial production workshops. In high-temperature environments, stable counting performance can be maintained through a reasonable heat dissipation structure; in low-temperature environments, the internal circuit can also start and run normally, ensuring the continuity of counting work and the stable progress of industrial production.
Storage Temperature: In the storage state, it can withstand extreme temperatures from -40°C to 85°C, which can meet the temperature requirements of the product in transportation, storage and other links, ensuring that the module can still be used normally after long-term storage without performance degradation or damage due to temperature issues.
Anti-Electromagnetic Interference: It meets industrial-grade electromagnetic compatibility standards and has strong anti-electromagnetic interference capabilities. Through internal electromagnetic shielding and filtering circuits, it can effectively resist electromagnetic interference generated by equipment such as motors, frequency converters and electric welders in industrial sites, prevent counting errors caused by interference to pulse signals, and ensure the reliability of pulse counting.

III. Functional Characteristics
The core function of the IC693PCM311 module is to realize high-precision counting of pulse signals. It can accurately receive pulse signals from devices such as encoders, count the rising edge, falling edge or both edges of the pulses, and perform data processing according to preset counting modes (such as incremental counting, decremental counting, bidirectional counting, etc.) to obtain accurate counting results. The module has high counting accuracy, and can ensure the accuracy of counting results even when the frequency of pulse signals is high, providing reliable position, speed and other data support for the PLC system.
(2) Flexible Counting Mode Setting Function
The module supports multiple counting mode settings. Users can configure the counting mode of each counting channel through programming software according to actual application requirements. For example, it can be set to incremental counting mode to measure the forward movement distance of the equipment; set to decremental counting mode to measure the reverse movement distance of the equipment; set to bidirectional counting mode to measure the forward and reverse movement distances of the equipment at the same time, so as to realize accurate tracking of the equipment position. The flexible counting mode setting enables the module to adapt to different industrial control needs.

(3) Comparison Output and Alarm Function
The module has a comparison output function. Users can preset multiple comparison values. When the counting result reaches the preset comparison value, the module will send a control signal through the corresponding output interface to trigger actions of external equipment, such as shutdown, commutation, alarm, etc. At the same time, the module also has an alarm function. When abnormal situations occur during counting, such as loss of pulse signals, counting overflow, etc., it will send an alarm signal in time, and transmit the alarm information to the PLC processor through the backplane interface, facilitating the system to take timely countermeasures to ensure the safe operation of the equipment.

(4) Diagnosis and Status Indication Function
The module is equipped with perfect diagnosis function and status indication function, which is convenient for technicians to monitor the operation status of the module and troubleshoot faults. The module is equipped with power indicator lights, running indicator lights and status indicator lights for each counting channel. The power indicator light is on, indicating that the module is powered normally; the running indicator light is flashing, indicating that the module is working normally; when a certain channel is counting, the corresponding status indicator light will change accordingly, so that technicians can intuitively understand the working status of the module. At the same time, the module can also diagnose its own fault status and transmit the fault information to the PLC processor, facilitating the system to perform fault alarm and handling.
