Message communication modes which can be used with MHPs are shown below. Available message modes vary depending on the communication protocol.
The figure below shows the message communication modes.
Figure 3-6 Message communication modes

The message communication facilities which are available to MHPs and SPPs are as follows:
To use the function dc_mcf_send() with an SPP, the SPP processing must be operating as a transaction.
For an MHP using message exchange facilities, specify the type of application according to the message communication mode to be used. Specify the type of application for the type operand of the MCF application definition or the application attribute definition (mcfaalcap). There are the following three types of application:
Specify noans for the mode in which a message, received with the function dc_mcf_receive(), is sent to the logical terminal of the input source by using the function dc_mcf_send().
For MHPs, specify the type of application according to the message handling mode. This specification is not required for SPPs.
If the specified type of application conflicts with the message handling mode, a message exchange function returns with an error or the MHP processing is rolled back. The type conflicts with the mode in the following cases:
The application type of the MCF event handling MHP is determined by the reported MCF event. See 3.10 MCF events for details.
The table below shows the correspondence between the types of application and message exchange functions.
Table 3-9 Correspondence between the types of application and message exchange functions
| Message Mode | Types of Application | Functions for Message Processing | ||||||

The following tables indicate what functions are available in each of the communication modes used by OpenTP1-provided products conforming to different communication protocols.
