07KR51 1SBP260011R1001 Field Control Station

07KR51 1SBP260011R1001 The core part of the PLC system is a high-performance modular S7-300/400 series PLC from SIEMENS, which completes the collection and adjustment of process parameters and the start/stop control of process equipment in the production process, and is placed in the control room of the production site to shorten the distance from the site to the primary detection components and actuators. It is placed in the control room of the production site to shorten the distance to the primary detection elements and actuators. A variety of modular components in different ways conveniently combined together and suitable for dense installation, structural form specification, improve the flexibility of the design of the automatic control system and the reliability of the operation, due to the need to deal with a large number of signals, the use of multi-rack mounting.

07KR51 1SBP260011R1001 CPU module has a variety of different properties, for example, some CPU integrated with input / output points, some CPU integrated with PROFI-BUS-DP communication interface, etc., the production line automatic control system CPU is specially upgraded to a higher level, the use of the CPU for the 413 model (later due to lightning strikes one of the reasons) replaced by CPU412-2)

07KR51 1SBP260011R1001 is used for digital and analogue input/output, which is the interface between the PLC system and the production process; the starting, stopping, limit alarms, fault alarms, operation and running status of the field equipment, as well as the temperature, pressure (differential pressure), flow rate, voltage, current, rotational speed, and other important parameters are all connected to the PLC system through these signal modules. The DI signal module used in this system is SM321, DO signal module is SM322, AI signal module is SM331 and AO signal module is SM332.
