3、Address）Valid munication addresses are in the range of 031. munication address equals to 0 means broadcast to all PLC, the PLC will reply normal message to the master device. For e*ample, munication to PLC with address 16 decimal:(ADR 1, ADR 0)=1,01=31H, 0 = 30Hn CMD (mand code) and DATA (data chara

The following depicts the cond

9、itions that no normal response is replied to the master device.The PLC does not receive the messages due to a munication error; thus the PLC has no response. The master device will eventually process a timeout condition.The PLC receives the messages without a munication error, but cannot handle it,

10、an e*ception response will return to the master device. In the e*ception response, the most significant bit of the original mand code is set to 1, and an e*ception code e*plains the condition that caused the e*ception is returned.An e*ample of e*ception response of mand code 01H and e*ception 02H:ma
