4-5 Using the Event Input
4-5-1 Setting the Event Input
The event input, which uses an external contact input, is set using the “No. of
multi-SP uses” and “event input assignment” settings.
The multi-SP function is allocated for event input by setting the “No. of multi-
SP uses” parameter. The RUN/STOP control function is set using the “event
input allocation” parameter.
When the event input is not used as a multi-SP function, the multi-SP function
can be used via host communications or the E5ZN-SDL Setting Display Unit
by setting the “multi-SP use” parameter.
The following table shows the relationship between the three settings.
The shaded areas indicate the default values for the “No. of multi-SP uses,”
“event input allocation,” and “multi-SP use” parameters.
The three communications parameters given in the left columns of the above
table are given priority in the following order: “No. of multi-SP uses,” “event
input allocation,” and “multi-SP use.”
4-5-2 Using Control Start (RUN)/Control Stop (STOP)
When the “No. of Multi-SP uses” parameter is set to 0 and the event input allo-
cation is set to “RUN/STOP,” the RUN/STOP function can be controlled using
the event input. The following table shows the relationship between event
input contact status and control status.
4-5-3 Using the Multi-SP
The multi-SP function is used to switch between two SPs. Different SPs are
set in advance for SP 0 and SP 1 and the event input contact signals or E5ZN-
SDL Setting Display Unit is used to switch them.
Using the Event Input The SPs listed in the following table can be selected by turning ON and OFF
the event input.
Note 1. Switch event inputs while the power is ON.
ON/OFF is detected for inputs of 50 ms or more.
2. SPs for ch1 and ch2 are both switched at the same time using event input.
