CM01 CM01-A-V001 has the following characteristics:

A, the production environment is harsh, dusty, vibration increase;

B, belongs to the process control, logic flow, the logic of the equipment is more complex relationship;

C, most of the weighing and batching process, and the accuracy and efficiency requirements are higher, the equipment is running faster conversion state; D, the customer’s ability to maintain the equipment is low, the control system and the efficiency of the control system.

D, the customer’s equipment maintenance capability is low, the stability of the control system and electrical equipment required for higher.

E. Customers require the lowest possible investment.

CM01 CM01-A-V001 self-developed modules compatible with Siemens S7-200 and S7-300 are used in the control system of concrete mixing plant and the control system of aerated block production line of building materials production line respectively, in this case, EVERGREEN PLC fully demonstrates its strong stability and price advantageous highlights. Concrete mixing plant mainly realises the measurement of raw materials such as sand, stone, cement, fly ash, water and additives, and feeds them to the mixer according to a certain set order, and unloads them after mixing for a period of time.

CM01 CM01-A-V001 Features:

A, the requirement of high efficiency, equipment is intermittent operation, but the requirements of the production efficiency as far as possible to the continuous operation close to.

B, high dosing accuracy, the national standard requirements of sand and gravel dynamic metering accuracy of ≤ 2%, powder and liquid material accuracy of ≤ 1%, especially additives, the dosage of sometimes ten kilograms, the error can not be more than 0.1 kilograms, which is still in the mixer vibration is particularly large occasions; C, the production management requirements are high.

C, production management requirements are relatively high, the production data required to record all, including any manual operation by the user, all the requirements of the manual operation signal through the PLC into the microcomputer.

CM01 CM01-A-V001 system has about 120 I/O points, DI and DO points are basically equal, in order to solve the above problems, we use Siemens S7-200PLC 214 CPU module, the rest of the I/O modules and AI modules for water content detection using YIVEI’s UN200 series, the dosage metering using the batching control instrument PLY600 developed by Shandong Boshuo. In the UN200 module, the 8DI/8DO digital module is also used as the keyboard scanning module to collect signals for manual operation.
