Total transmission speed of two interfaces is available up to 230.4kbps.Total transmission speed of two interfaces is available up to 115.2kbps when the communication data monitoring function is used.

Access Cycle

MC Protocol

Processes one request during installed C24 CPU module END processing. (Number of scans that must be processed/number of link scans depends on the contents of the request.)

Pre-Defined Protocol

Sends or receives data when requested with the dedicated instruction (CPRTCL).

Nonprocedural Protocol

Sends data each time a send request is issued. Can receive at any time.

Bidirectional Protocol

Error Detection

Parity Check

All protocols and when ODD/EVEN is selected by parameter.

Sum Check Code

MC protocol/bidirectional protocol selected by parameter. For the pre-defined protocol, whether or not a sum check code is needed depends on the selected protocol. Nonprocedural protocol selected by user frame.

Transmission Control

• DTR/DSR signal control and DC code control are selected by the user.
