IC660EBD025 Output Module Base  

IC660EBD025 must ensure the high reliability of data transmission and control security, to avoid the phenomenon of loss of control and wrong control instructions, this system is mainly through the following aspects to ensure: wireless digital transmission module of high anti-jamming ability and low BER, efficient forward error correction channel coding technology. Serial communication protocol calibration, generally using parity check;

IC660EBD025 software protocol checksum; through software programming, the data sent to the checksum, can be used CRC checksum, interactive confirmation or multiple send comparison. In our program, we use the same action instruction to send repeatedly, only the command instruction and the confirmation instruction are exactly the same, the PLC accepts the instruction, otherwise the instruction is ignored. This completely avoids the error instruction generated by the communication.

IC660EBD025 “software watchdog”; in the PLC program to set a timer program, when the timeout does not receive the wireless command, to stop the robot action, to prevent the robot out of control due to the interruption of communication.
