2. Terms and Definitions

2 2. Terms and Definitions Term Description / Definition Protocol Macro This function enables data Send / Receive with general-purpose external devices by storing the data Send / Receive procedure (Protocol) used with the general-purpose external devices in the Serial Communication Board or Unit and executing the PMCR instruction in the CPU unit. Protocol The unit that comprises an independent communication processing for a specific general-purpose external device as a data Send / Receive procedure is called a "Protocol". A "Protocol" consists of multiple "Sequences".

Sequence A unit of independent communication processing that can be activated from the PMCR instruction on the ladder program. The activated sequence sequentially executes the steps included in it. Step A unit of data to execute any Message or other Send / Receive process, Receive Buffer Clear, and Step Waiting process. A maximum of 15 Steps can be set for 1 Sequence. Send Message A communication frame (Command) sent to a general-purpose external device. It is called from a Step in the sequence and sent to a general-purpose external device. Receive Message A communication Frame (Response) sent from a general-purpose external device.

It is called from a Step in the sequence and compared with the data received from the general-purpose external device. Receive Matrix The Receive Matrix is used when it is not possible to identify only one communication frame (response) sent from a general-purpose external device. It is possible to register multiple communication frames in the Receive Matrix. Case A unit to register multiple communication frames (responses) in the receive matrix. 1 communication frame is registered as 1 case. It is possible to register a maximum of 15 case types in the Receive Matrix.
