The terms and definitions used in this guide are given below.
Term Explanation and Definition
protocol macro Data transfer procedures (protocols) with general-purpose external
devices are created and stored in Serial Communications Boards or Serial
Communications Units. These protocols enable data to be exchanged with
general-purpose external devices by executing the protocol macro
instruction (hereinafter referred to as "the PMCR instruction") in a CPU
Unit.
protocol A set of rules governing the data transmission procedure that unifies
independent communication processes for a specific general-purpose
device. A protocol consists of more than one sequence.
sequence An independent process that can be performed by executing the PMCR
instruction in a program. The sequence started by the instruction executes
its steps in a given order.
step A unit to execute any one of the followings: message send processing,
message receive processing, message send/receive processing, receive
buffer clear or step wait. Up to 15 steps can be created per sequence.
send message A communication frame (command) sent to a general-purpose external
device. The send message is invoked by steps in the sequence and is sent
to general-purpose external devices.
receive message A communication frame (response) sent from a general-purpose external
device. The receive message is invoked by steps in the sequence and is
compared with data received from general-purpose external devices.
receive matrix A function to register and use some communication frames (responses)
when more than one communication frame is expected to be received from
a general-purpose external device. The receive processing can be
executed according to registered communication frames by using this
function.
