Methods of operation with the ASM
Commands are executed one at a time
This means that, after each command, the user must wait for the acknowledgment (result)
before the next command is sent to the ASM. This type of programming involves the
following characteristics.
•
Simple function block programming
•
No optimal-speed data transmission for several consecutive commands
The following diagram shows the sequence of command and acknowledgement exchange
between user (DP master) and MOBY-ASM.
