4.7 How to Use Transfer Output
• Whe n using trans fe r outpu t, add on the communicat ions unit
(E53-AKF).
• You can select the following data items in the “transfer output type”
parameter (option mode) as the transfer outputs:
Set p oint
Set p oint during SP ramp
Process value
Manipulated variable (heat)
Manipulated variable (cool), and
Valve opening.
However, note that heating/cooling side manipulated variables can be
output only standard type controllers, and valve opening can be out-
put on position-proportional type controllers
• If the output assignment is changed when either ”manipulated vari-
able (heat)” or ”manipulated variable (cool)” parameter is selected,
the default ”set point” is returned to.
• Thesetransferoutputscanbescaled according to the settings of the
“transfer output upper limit” and “transfer output lower limit”
parameters before output. Setting of an upper limit value smaller
than the lower limit value is allowed, so reverse scaling can also be
carried out. Also, the scale can be enlarged by the upper-and lower-
limit width specified for each data item. The following example shows
scaling of the reading side manipulated variable.
