Click key and place it in the display area. In a control system, the data operation is
necessary. So this “Register” places a key role in the control system.
Register:
Register number: Set this register’s number. Take D0 as the example, the panel can
directly monitor the changing of value in D0.
When choosing “Set”, then this register will also set function, there will be also
two items: Encrypt and low (up) limit.
Encrypt:
To improve the device’s safety, all the set parameters can be protected by the password.
For the password setting and modifying, please refer to the next chapter.
Up/Low limit:
The designer can set Up/low limit, this will make the data, which exceeds this limit, invalid.
This could protect the device when input too large or too low data. For example, when
setting the up value as 9000, the low value as 0. Only when its greater than 0 the set value
or below 9000, the set value could be written into the PLC.
Display:
Here, set the register’s display units and decimal bit, at the same time choose the
display mode.
