532-5HD00-0AB0 Siemens module

Memory card:

Used to expand the built-in loading memory. In addition to the program itself, the information contained in the loading memory also includes the configuration data of S7-400H F/FH, which is why it occupies double the space in the memory. The result is:

The built-in loading memory cannot meet the requirements of large program volumes, therefore a storage card is needed.

Provided with RAM and FEPROM card (FEPROM is used to save data when the power is disconnected).

Flexible expansion options:

Up to 131072 digital inputs and 81932 analog inputs/outputs.

MPI multi-point interface:

Modern PLC has the function of network communication, which can control remote/O and achieve communication between PLC and computer, thus forming a distributed control system of "centralized management and decentralized control" and realizing factory automation. PLC can communicate with various RS232 devices through RS232 interface. PLC can communicate with other intelligent control devices such as frequency converters and numerical control devices

PLC

Forming a joint control system with a frequency converter can improve the automation control level of AC motors.

7. Data processing

Modern PLC has functions such as numerical calculation (including matrix operation, function operation, logical operation), data transmission, data conversion, sorting, table lookup, and bit operation, which can complete data collection, analysis, and processing. These data can be compared with reference values stored in memory to perform certain control operations, and can also be transmitted to other intelligent devices through communication functions, or printed and formatted

The CPU takes less than 18.75 ns to process each binary instruction.

4 MB main memory (2 MB for programs and 2 MB for data);

Loading memory is used to store user programs and configuration data for the S7-400H F/FH automation system; High speed main memory is used to store subroutines of user programs related to processes

PLC has the function of timing control, which provides users with several timers. The timer time can be set by the user when writing the program, or can be set externally using a dial switch to achieve timing or delay control. Positioning control is one of the control functions of PLC. PLC provides intelligent modules such as positioning module and pulse output module to achieve positioning control for various needs. PLC has the function of counting control, which provides users with several counters or high-speed counting modules. The count value of the counter can be set by the user when writing the program, or it can be set externally using a dial switch to achieve counting control. 5. Sequential (step-by-step) control

In industrial control, using PLC to implement sequential control can be designed using the standardized language for sequential control specified by IEC - sequential function diagram. Programs can be written using shift registers and sequential control instructions.
