Parameter Access; Writing Parameters; Write Frequency Parameter - BONFIGLIOLI AGILE Applications Manual

The output value is determined according to the following table:
I3 I4 O=
0 0 I1
1 0 I2
x 1 P2|P1
Note:
Output value O2 is not the inverted value of O1.
The output can be combined with inputs for position values (Long).
The function can also be used for ramp settings in configurations x40.
The availability of configuration x40 depends on the device series.

Writing parameters

Parameters can be written from the PLC functions. This is done in two steps.
− The PLC function puts the write request, including all data, on a list.
− This list is processed in non-realtime system. In this process, redundant write commands on
the same parameter are deleted. The list can contain a maximum of 8 write commands.
The output is TRUE if the list is full and cannot accept any more write commands.
If the parameter number is outside of the range 0 ... 1599, only the status of the buffer is
checked and the output is set, if applicable.
Any errors during the write process will be ignored.
If input I4 "Wait" is TRUE, zero operations (NOP) will be inserted if the write buffer is full until
the write command can be entered in the buffer. If input I4 "Wait" is FALSE, write commands
may be lost in the case of a buffer overflow.
If input I2 "Delete buffer" is TRUE, the write buffer will be deleted first before the new write
command is entered.
The target parameter of the write command is defined by P1. The target data set is defined by
P2.
