Pin Description
Input INC
When INC was activated, the system time will increase 1
hour automatically.
DEC Input When DEC was activated, the system time will decrease 1
hour automatically.
Function Description:
When there is a high potential on INC, the system time will increase 1 hour
automatically, when there is a high potential on DEC, the system time will decrease 1
hour automatically.
3.2.15 Explanation to Property Pin (The property pin of TOND, TOFD, BLNK,
MTOD, PONS, UDCT, CMPR function blocks)
There is an output pin defined as the property pin in the TOND, TOFD,
BLNK, MTOD, PONS, UDCT, CMPR function blocks. And also one output pin of
SLCD is also defined as the property pin.
Meanings of Property Pin:
Property pin can only be connected with other property pins. After
connection, it will transfer the time/counter/analog and so on parameters the SLCD.
When SR-HMI is used, it will display the parameters of the function block according
to the relationship of the property pins.
Fig. 3.9
As shown in Fig. 3.9, when HMI is turned to L:0 page, the set time of B0 and
the current time will be displayed.
Fig. 3.10
As shown in Fig. 3.10, when the output pin of B0 is high, HMI will show L:0
page automatically and display the set time of B0 and the current time.
