Start
A
When 1 (Setting) is set to request command, the
SR
Mini HG SYSTEM
starts reading the temperature set
value data set to the register (memory) on the PLC
side.
If 1 (Writing on monitor data) is set to PCP
communication state in the PLC, this indicates that
temperature set value data have been read to start
writing
SR Mini HG SYSTEM data items such as
temperature measured values (PV) etc. (attribute: RO)
into the PLC.
If 2 (Reading out setting data) is set to PCP
communication state in the PLC, this indicates that
temperature set values data are being read from the
PLC.
Set temperature set value
(SV) and other setting data
to each register (memory)
in the PLC.
Set “1” to the request
