4.9 How to Use Transfer Output
Ă• When using transfer output, add on the communications unit
(E53ĆCKF).
Ă• You can select the following four data items in the transfer output type"
parameter (option mode) as the transfer outputs:
Present SP (default), Process value, Manipulated variable (heat),
Manipulated variable (cool).
Ă• If the output assignment is changed when either the manipulated variĆ
able (heat)" or manipulated variable (cool)" parameter is selected, the
factory setting set point" is returned to.
Ă• These transfer outputs can be scaled according to the settings of the
transfer output upper limit" and transfer output lower limit" paramĆ
eters before output. Setting of an upper limit value smaller than the lowĆ
er limit value is allowed, so reverse scaling can also be carried out. Also,
the scale can be enlarged by the upperĆ and lowerĆlimit width specified
for each data item. The following example shows scaling of the heating
side manipulated variable.
