| Abstract: | The communication between main PLC and Upper PC for the control system of new type ZJ19 cigarette making assembling set was realized with Siemens protocol, network adapter, and configuration software of Uper PC or function library. In order to make Prodave to work steadily under multi-thread circumstance, the communication data was classified and the strategy of command queue was adopted. Data exchange among threads was realized under the protection of critical section. This communication approach has the following advantages: high reliability, low cost, simple program, easy to use and maintain. |
