6. Communication for master station
■ Precautions for programming
• The longest response time of the instrument is 2sec.
Therefore, the response monitor time should be set to 2sec.
• If no response is obtained within 2sec, retransmit the same message. When no
response remains coming even after making retransmission twice, it should be
regarded as a communication error.
• The above-mentioned retransmission is required since a message may not be
properly transmitted due to noise or the like during communication.
Note
When the device distinction codes "X" and "x" are used alternately during
message retransmission from the master station, the received response message
can be conveniently identified to be the latest message or preceding one.
