ILX69-PBS

通信程序的工作过程：PC每发送一个字节前首先发送握手信号，PLC收到握手信号后将其传送回PC，PC只有收到PLC传送回来的握手信号后才开始发送一个字节数据。PLC收到这个字节数据以后也将其回传给PC，PC将原数据与PLC传送回来的数据进行比较，若两者不同，则说明通信中发生了误码，PC机重新发送该字节数据;若两者相同，则说明PLC收到的数据是正确的，PC机发送下一个握手信号，PLC收到这个握手信号后将前一次收到的数据存入指定的存储区。这个工作过程重复一直持续到所有的数据传送完成。

采用软件握手以后，不管PC与PLC的速度相差多远，发送方也不会超前于接收方。软件握手的缺点是大大降低了通信速度，因为传送每一个字节，在传送线上都要来回传送两次，并且还要传送握手信号。但是考虑到控制的可靠性以及控制的时间要求，牺牲一点速度是值得的，也是可行的。

PLC方的通信程序只是PLC整个控制程序中的一小部分，可将通信程序编制成PLC的中断程序，当PLC接收到PC发送的数据以后，在中断程序中对接收的数据进行处理。PC方的通信程序可以采用VB、VC等语言，也可直接采用西门子组态软件，如STEP7、WinCC。
