Communication Format
HECR 3-2
3.3 Communication procedures and format
The host computer has the initiative of sequence. Sequence always starts from the host computer
and each Thermo-con replies it.
If communication data is processed normally, the Thermo-con returns specified response and if
processing communication data is failed, no response is returned.
When no response is returned to the host computer from the Thermo-con even if waiting for 3 sec.,
resend the data. The Thermo-con returns response after waiting for 50 msec.
For communication of plural number of communication data, wait until the return message is received
from the thermo-con to send the next communication data. It sometimes cannot return the messages
properly when the communication data is received successively.
Selection of Unit Specification
･There are two cases in communication format, which are specifying unit No. and not.
･When one Thermo-con is used, select “without specifying unit” and when two or more Thermo-cons
are used, select “ with specifying unit”.
･When several Thermo-con are used with without specified unit No., correct control is not realized due
to data conflict.
･In the case of use with specified unit No.,ensure to coincide communication No. and each Thermo-con
unit No.
