Need help. PanelView_Info and Switch_Enable_PLC

[SirJay 0]

Good day team,
I would like to seek for your help.
I'm very new to reading PLC.
My co-worker had a PLC tester VB.net.
He is also not well knowledgable in PLC.
The program is in my dropbox: https://www.dropbox.com/s/3t0c2iabvsfhu5d/PLC_Tester.rar?dl=0

Our problem is how to read these two:
1. panelview_info
2. switch_enable_plc

Sample codes are in the function:
1. CallRead_PanelViewInfo
2. CallRead_SwitchEnablePLC4
3. CallRead_SwitchEnablePLC5
4. ReadComplete_PanelViewInfo
5. ReadComplete_SwitchEnablePLC4
6. ReadComplete_SwitchEnablePLC5

The values being returned are like process points like "1.123456".
However, what I need is if those machine specific parameters are turned on and off.
Again, machine parameters (not the recipe paramemters).

I would like to ask if anyone here has example on how to read:
1. panelview_info
2. switch_enable_plc

Thank you team.
