8: What is a Baud Rate?

A.   Baud, synonymous to symbols per second, or pulses per second, is often times referred to as the unit of the symbol rate –

B.   It is the number of distinct symbol changes made to the transmission medium per second in a digitally modulated signal or a line code –

C.   Both A & B

D.   None of the these

9: What communication protocols are applicable to our HMI line?

A.   RS232

B.   RS422

C.   RJ-45

D.   All of these

10: Which PLC unit do I select if my PLC is not listed under compatible PLC′s?

A.   Selecting a PLC depends on what protocol this PLC or controller uses

B.   If the controller uses Modbus RTU, then the user should select Modbus RTU Slave. If the controller uses ASCII, then the user should select the Universal ASCII slave.

C.   Both A & B

D.   None

11: What is Windows CE and what is the Codesys packet?

A.   Windows CE in an embedded operating system, which translate to a very stripped and minimalistic copy of windows for smaller devices such as HMIs and cellular phones

B.   The Codesys′s packet is a proprietary third party software, which will give allow the user to program an HMI and PLC.

C.   Neither A or neither B

D.   Both A&B

12: What type of touch panel do these Kinco HMI′s use?

C.   In case the controller being used is not considered compatible with the HMI

D.   All of the above

15: What are the benefits of an HMI over a desktop?

A.   Application-specific

B.   A panel will not allow for internet browsing, solitaire game play, or update reminders unless it pertains to the task at hand

C.   HMIs provide absolute control; meaning that you may give the user limited access to specific features, or full access depending on how the interfaces are created.

D.   Both A&B

E.   Both A&B&C
