 Data transfer procedures
Change each set value of SR Mini HG SYSTEM from the PLC after the initial settings
are made.
If each set value of SR Mini HG SYSTEM is changed from the PLC without setting the
initial values, it is re-written to 0 with each set value of the PLC at that time set to 0.
 Initial Setting (When transmit data of temperature setting values from SR Mini HG
SYSTEM to PLC)
Start
Reserve data write time as wait time. In addition,
process data in each item as indefinite during this
period.
Waiting time (for 38400 bps):
Approx. 1 second/control unit
Turn on power of
each instrument
When 2 (Set value monitor) is set to request command,
the
SR Mini HG SYSTEM starts writing the data items
such as temperature set value, etc. (attribute: R/W) to
the PLC side.
If 3 (Writing on setting data) is set to PCP
communication state in the PLC, this indicates that
SR
Mini HG SYSTEM
data items such as temperature set
value, etc. (attribute: R/W) are being written into the
PLC.
YES
NO
Set “2” to the request
command
PCP communication
state = 3 ?
If 1 (Writing on monitor data) is set to PCP
communication state in the PLC, this indicates that
SRV data items such as temperature set value, etc.
(attribute: R/W) have been written to start writing
SR
Mini HG SYSTEM
data items such as temperature
measured values (PV), etc. (attribute: RO) into the
PLC.
