IS230SNCIH6A Analogue Input Unit

IS230SNCIH6A as a control element, its control system is complex, difficult to operate, and installation and wiring workload, difficult to modify the control strategy, maintenance, seriously affecting the normal production. Therefore, the material handling control system has become the bottleneck of production. The control system composed of PLC with high reliability and its WINCC monitoring software [1] is used as the main equipment for data acquisition, control loop, automatic sequential operation and arithmetic.

IS230SNCIH6According to the equipment and process requirements, the packaging and conveying system is composed of an upper and a lower computer, and the upper computer uses two PCs: one as an operating station to achieve the monitoring of the entire system and data detection; the other as an engineer station to complete the design and development of the configuration software, the development of the PLC program, and the software is transmitted to the PLC through the PROFIBUS [2] bus to the CPU unit.

IS230SNCIH6A lower unit adopts powerful, highly reliable, easy to maintain and anti-interference ability of the programmable controller Siemens S7-300 series PLC to complete the control function of the equipment, and the lower unit is divided into two racks were placed in the packaging warehouse and bulk storage. Bulk storage rack and packaging room rack S7-300 constitute PROFIBUS-DP network structure. The control mode of the packaging and conveying control system is divided into three types: automatic control, stand-alone control and on-site manual control.
