Example 4
Open the example project. The block used for this example is FC 104.
Note: If you call the example 4 in OB 1, then please do not call the examples 1 to
3 at the same time; otherwise, data would be overwritten.
In this example, the HMI interface signals for the data range from DBB 498 through
DBB 515 are transferred to the interface area for the control signals, e.g. the
modes (see Section 8.2).
You can trigger write and read jobs by assigning the data fields to be transferred
the appropriate parameters and data.
For example, if you select the machine data screen PIC_763, you can write an MD
using the ”set” softkey (SK) and read an MD using the ”read” softkey (SK).
Once you have selected the mode screen PIC_75 on the operator panel and
selected the appropriate mode SK, the selected mode will be accepted into the
control signals of the interface, and the appropriate mode will be set.
If you select the diagnostic screen PIC_77, you can acknowledge an error by
pressing the ”Quit” SK or acknowledge a diagnostic alarm by pressing the ”Res”
SK.
In this way, all interface signals which can be activated by the OP are requested.
You can assign default values to all data fields and transmit trigger pulses for the
jobs to be executed.
