Hi,
    I used the PIGCS2Src in motor-6-8 to drive the PI E712 piezomotor controller.
    But there are two error messages as starting up
1.PIasynController: unknown controller type e712
2.writeFloat64() GCS controller not initialized!
   
 And the detail of the startup message is following:
   
#!../../bin/linux-x86_64/e712
## You may have to change e712 to something else
## everywhere it appears in this file

Are there any mistakes in my st.cmd writing?
