Event Input; Transfer Output - Omron E5CK User Manual

CHAPTER 4 APPLIED OPERATION
F Multi-SP
J Transfer output
Parameters
4--8
The set points set to the "set point 0" and "set point 1" parameters (level
1 mode) can be switched for use. However, note that these parameters
cannot be set when the multi-SP function is not selected.
The set point can be switched up to 100,000 times.
When event input is "OFF", set point 0 is used, and when "ON" set point
1 is used.
When you have changed the set point, the set point of the currently
selected parameter is changed.
When you have switched between "set point 0" and "set point 1", the SP
ramp function works if the SP ramp function is enabled. The following
examples shows how the set point changes when you switch from set
point 0 and set point 1.

Event input

When using transfer output, add on the communications unit (E53-CKF).
You can select the following data items in the "transfer output type"
parameter (option mode) as the transfer outputs:
Set point
Set poing during SP ramp
Process value
Manipulated variable (heat), and
Manipulated variable (cool).
These transfer outputs can be scaled according to the settings of the
"transfer output upper limit" and "transfer output lower limit" param-
eters 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 speci-
fied for each data item. The following example shows scaling of the read-
ing side manipulated variable.
