mands in case noise or other factors result in transmission errors.
Parameter
Meaning
Command
One of the following: SEND, RECV,

and receive
message
The message sent and the expected mes-
sage for SEND&RECV.
Reception
matrix
A group of expected messages that can be
used to switch to different next processes
when RECV or SEND&RECV is used.
Repeat counter
The number of times to repeat the step (0 to 255). The
repeat counter can be used to change send/receive mes-
sages.
Retry count
Used for SEND&RECV to retry the command for errors (0 to
9).
Send wait time
Used for SEND or SEND&RECV to create a wait time before
sending data.
Response write
