Moka7 -- DBGet() Problem

[Özkan ERÖZCAN]

Hi ,

I want to control PLC by Java. So I'm using Moka7.
But I Can't read DB's from PLC Siemens #S71200 #CPU 1212C AC/DC/RLY #212-1BE40-0XB0 #fw:4.2

PLC Configuration:
Optimized Block Access... unchecked
Full Access... selected
Permit access with PUT/GET... checked

+================================================================
| ConnectTo()
+================================================================
Connected to : 192.168.0.1 (Rack=0, Slot=0)
PDU negotiated : 240 bytes
Execution time 68 ms

+================================================================
| GetPlcStatus()
+================================================================
PLC Status : RUN
Execution time 7 ms

+================================================================
| DBGet()
+================================================================
S7 function refused by the CPU.
Execution time 8 ms

+================================================================
| ReadArea()
+================================================================
DB 1 succesfully read using size reported by DBGet()
Execution time 0 ms

I connected to PLC but I can't control DataBlock.
Can you explain it simply?

Thank you.
Best Regards

You can't use DBGet() with S71200/1500 with all Snap7 family (Snap7,Moka7,Sharp7....)
