HIMA F8621A Communication Module

HIMA F8621A Communication Module

F8621A has realized the connection with PLCs of Siemens, Delta, and Deveson through Modbus RTU transmission protocol. In addition to normal start, stop, forward, reverse, parameter monitoring, fault reset function, but also according to the user’s needs, to achieve customized curve operation. Users should pay attention to the PLC’s communication function definition when using the communication function, only when the PLC sends out the format that the frequency converter can recognize, i.e. Modbus RTU communication frame, the frequency converter can run correctly according to the instruction.

F8621A Before writing the PLC program, the characteristics of the system and the operation process should be analyzed first. In the general industrial production process, each device in the system starts in the initial state. Initial state includes: a. For equipment power supply is normal. b. Equipment selected in the automatic mode, that is, PLC control mode. c. The protection, control and signaling of the equipment has been reset. After determining that each piece of equipment to meet the initial state, the operator issued a start command, the entire system from the initial state into the starting process. The whole system starts the starting process from the initial state. If any one of the equipment does not meet the initial conditions for starting in the self-test, the starting operation cannot be carried out. In the starting process, the state of each device is constantly changing, and each individual device starts to run according to the process sequence, advances to the stable operation state, and finally enters the stable operation state.
