Direct Connection Function Section 1-41-4-2 C200H Direct CommunicationAdvantage of C200H Direct CommunicationCautionC200H direct communication allows communication with CjjH, C200H, andC200HS CPU units by using the “direct connection” function.S Since an I/O connecting cable is used for connection to each CPU unit, highspeedcommunication is possible.S Data can be written to the PC memory area in bit units, This means that the unusedbits of words allocated to touch switches can be used for other applications(for example, lamp allocations.)The C200H direct communication function is compatible with the host link and NTlink functions. This means that NT600S screen data and PC programs handledwith the host link and NT link functions can also be used with the C200H directcommunication function as they are.In a system where the user program operates according to the PC cycle time, thesystem operation may not be constant because of cycle time fluctuations.Consider this point when designing the system.15ηττπ://νιχοντρολσ.χοm
