(-R2/R4) (-R2)
These functions allow the following codes to be registered as the
changeable data of user frames for data communication.
• Horizontal parity code
• Sum check code of two's-complement number
This function allows reception of a message consisting of the head frame
and any data field when receiving data by specifying the head frame.
The data length of the data field can be specified freely for each
combination of user frames for reception set by the user.
(Receiving 1 byte providing ACK/NAK only is also possible by setting the
data length of the data field to "0.")
This function allows specification of a maximum of 10 types of transparent
codes for transmission per interface when sending data using one of the
following protocols:
• Non procedure protocol
• Bidirectional protocol
This function allows the GX Developer connection mode to be switched by
an external device or the programmable controller CPU.
This function allows the monitoring of communication data transmitted on
the communication network of the Q series C24 and an external device.
The UINI instruction allows change of the mode, transmission specifications
and host station No. of the Q series C24.
This function allows to access station No. 65 to 120 of the CC-Link IE
Controller Network, CC-Link IE Field Network.
This function allows access to link direct device LW10000 or higher.
This function allows access to extended data register D65536 or higher and
extended link register W10000 or higher.
This function allows access to the control/non-control CPUs specified by the
user when performing the following forms of data communication with a
multiple CPU system:
• Communication using the MC protocol
• QCPU access from GX Developer
Data can be transferred with the protocol appropriate to the communication
target device.
