The CPU module of the EPSCPE100-ABAC exchanges data with various I/O modules, special function modules, communication modules, etc., which are mounted on the substrate, through the system bus (generally made on the printed circuit of the substrate), and the more modules are mounted, the time for data exchange between the CPU module and those modules increases. This increase in the time for data exchange will, to a certain extent, lengthen the scanning time of the PLC.

EPSCPE100-ABAC makes the system bus transmission speed high-speed: increase the bandwidth of the system bus so that the amount of data transmitted at a time increased, such as Mitsubishi Electric’s small Q series PLC, increased the bandwidth of the system bus, so that the amount of data transmitted is twice as much as the previous one; in the way of the system bus access, the use of continuous group transmission technology to achieve high-speed batch transmission of continuous data, which greatly shortens the time required to access each word. In the system bus access method, continuous group transmission technology is adopted to achieve high-speed batch transmission of continuous data, which greatly reduces the time required to access each word; and the system bus is effectively utilised by achieving global transmission to the modules connected to the system bus, i.e., transmitting the same data to multiple modules at the same time.

The core part of EPSCPE100-ABAC is PLC system, which adopts SIEMENS high-performance modular S7-300/400 series PLC to complete the collection and adjustment of various process parameters in the production process as well as the start/stop control of process equipment, and it is placed in the control room of the production site to shorten the distance from the on-site primary detecting elements and actuators. It is placed in the control room of the production site to shorten the distance to the primary detection elements and actuators on site. A variety of modular components in different ways conveniently combined together and suitable for dense installation, the structure of the form of norms to 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.
