6SN1123-1AB00-0BA2 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

MPI can be used to establish a simple network of 32 nodes with a data transmission rate of 187.5 Kbit/s. The CPU can establish up to 64 connections with nodes on the communication bus (C-bus) and MPI.

Note:

When using both PROFIBUS DP and MPI interfaces, only the following bus connectors can be connected to the MPI interface:

With socket: 6ES7 972-0BB42-0XA0

Without socket: 6ES7 972-0BA42-0XA0

PROFIBUS DP interface:

Through the PROFIBUS DP interface, redundant and distributed automation configuration can be achieved, thereby improving speed and facilitating use. For users, distributed I/O is handled as centralized I/O (with the same configuration, addressing, and programming).

PROFINET interface with 2 ports (switch):

Support system redundancy and MRP (Media Redundancy Protocol)
