VTCPD Features User Manual

If the host sends a message before the application executes a Resource block to receive

the message, VTCPD holds the host message. VTCPD can also be configured to send

messages asynchronously (see Asynchronous Replies and Reply Notification on page

89.)

To avoid possible race conditions, applications should ignore both intertimeout

and ertimeout after receiving the host message (see VTCPD Message Timing on

page 96.)

Receiving Message Headers

VTCPD supports either fixed length messages or variable length messages delimited

by a character or preceded by a header (see Message Format on page 46.)

In addition, VTCPD can be configured to remove (that is, strip) the header before it

sends the message to the application, or to send the entire message (including the

header).

If VTCPD is configured to send the header with the message, the application can be

set to parse (or process in some other manner) this header information. For

information about using composite folders to parse data, see the PeriProducer User’s

Guide.

For messages sent from the application, VTCPD always supplies the delimiter or

header.

messages using the message ID
