PD25 ITST
(■)
Communication control DI status(HEX):
To determine the DI contact status(12 points in total)
by bit setting method. Bit 0~11 of PD25 is correspond
to DI1~DI12.
In binary bits: 0: DI is OFF
1: DI is ON.
PD16 controls the input source, either from external
hardware terminals (DI1 ~ DI12) or communication
commands(correspond to Bit 0 ~ 11 of PD25). If the
bit of PD16 is 1, which means the source is
communication DI (PD25), If not, the source is
hardware terminal DI.
If the value read from PD25 is 0x0011, it indicates
that DI1 and DI5 are ON eventually.
If the value written into PD25 is 0x0011, which means
that the communication contacts DI1 and DI5 are
ON; but it does not mean that the terminal signals of
the DI1 and DI5 are ON, which is determined by
PD16 setting value.
For the function definition of DI(DI1~DI8), you can
refer to PD02~PD09.
For the function definition of DI(DI9~DI12), you can
refer to PD21~PD24.
Example 1
If set PD16 to 0FFFh and PD25 to 0000h. then all
DI1~DI12 will be controlled by the communication
contacts, and all digital input contact will be turned
OFF. If the external hardware terminals connect
DI1~DI12 to SG is conductive, the DI signal will not
be affected, but it still will be controlled by the
communication contact and the DI contact DI1~DI12
still will be OFF.
