A function available in GX Works2 and GX Configurator-SC (Predefined protocol support
function), which includes:
• Registration of the protocol appropriate to each target device
• Writing protocol setting data to or reading them from the flash ROM of the C24
• Debug support function
A user's communication procedure and one of the data communication functions for
communicating any data between the CPU module and a target device.
A communication procedure for the C24 and one of the data communication functions for
communicating any data between the CPU module and a target device
Generic term for the MC protocol, predefined protocol, nonprocedural protocol, and bidirectional
protocol
The memory of an intelligent function module and special function module used to store data
(such as setting values and monitored values) for communication with a CPU module.
A data string used for communication with target devices by the predefined protocol.
A name of the connection when multiple target devices or other C24 are connected in a 1:n or
m:n mode using the RS-422/485 interface of the C24.
This function registers character data (messages) to be sent to target devices (mainly printers) in
the C24 as a user frame in advance, and sends the registered data for multiple user frames using
the nonprocedural protocol.
Data name when the fixed format portion of messages to be sent or received between the C24
and a target device is registered in the module and used for sending and receiving data. (The
contents of a user frame data should conform to the specifications of the target device).
The data array of the head and tail sections of a message (transmission control code, C24 station
number, sum check, fixed data, etc.) to be sent and received is registered in the C24 before use.
This type of data is used in the on-demand function of the MC protocol and the data
communication function with the nonprocedural protocol.
A mode of interface operation to communicate data with target devices using a function specified
in each communication protocol setting. The interfaces of two C24s do not interact.
The operation mode of each of the two interfaces of C24s that are connected to target devices
and linked to one another in order to send/receive data to/from the target devices.
The two interfaces communicate data using the same data-communication function (MC protocol
(identical type) or nonprocedural protocol) and the same transmission specifications. (Linked
operation using the predefined protocol or bidirectional protocol is not allowed.)
