when the PLC integrated board entering abnormal detection module cannot receive the board entering abnormal packet for more than one time, firstly checking whether communication in the whole system is interrupted, if the communication is interrupted, prompting manual maintenance by the PLC monitoring module, otherwise judging that the industrial control application program is accidentally crashed, and restarting the monitored industrial control application program.
5. The automated first-in first-out sequential wiring production method according to claim 4, wherein the specific method for restarting the monitored industrial control application program is as follows:
judging system communication: when the PLC integrated board entering abnormal detection module cannot receive the board entering abnormal packet for more than n times, a marking signal is sent to the PLC monitoring module through a network, the PLC monitoring module immediately pins the PLC communication address IP after receiving the marking signal, i.e. the industrial control application program is abnormally crashed, and the Ping is not enabled, so that the communication problem is prompted to be maintained;
when the industrial control application program is abnormally crashed, the PLC integrated board entering abnormal detection module sends a restarting instruction to the PLC additional program through a TCP protocol, the PLC additional program is a second detection end, and the additional program starts a batch processing file to terminate the industrial control application program process and restart; the Ping, internet packet explorer, is a program for testing network connection amount under Windows, unix and Linux systems.
6. The automated first-in first-out serial line production method according to claim 1, wherein the warehouse-type first-in first-out temporary storage machine performs first-in first-out random switching by using a through mode;
when the storage type first-in first-out temporary storage machine temporary storage plate is utilized, the following steps are needed: and (5) preprocessing the microetching PCB and outputting the microetching PCB.
7. The automated continuous production method of first-in first-out sequences according to claim 1, wherein the warehouse-type first-in first-out temporary storage machine receives boards in abnormal sequences, and when the first-in first-out temporary storage machine is in normal production, the first-in first-out PCB board enters a film sticking machine for film sticking after the first-in first-out production is automatically realized according to the sequences.
8. The automatic first-in first-out sequence connection production method according to claim 1, wherein the Printed Circuit Board (PCB) subjected to film pasting is subjected to first-in first-out, sequence production and automatic production.
9. A PCB board, wherein the PCB board is subjected to film-bonding production by using the first-in first-out sequential automation line production method of any one of claims 1 to 8.
