Communications Buffer Channels
A communications buffer channel is a data buffer that interfaces the MSG-SNDE or MSG-RCVE function
with the communications device. This data buffer consists of one or more channels. Each channel is iden-
tified by a communications buffer channel number.
The communications buffer channel is associated with the connection based on the setting of the Ch-No
(Communications Buffer Channel Number) input parameter in the MSG-SNDE and MSG-RCVE func-
tions, and PARAM10 (Connection Number) in the parameter list (Param).
A connection refers to communications settings between the local station and a remote station. These set-
tings are set in the Transmission Parameters Tab Page of the MPE720 Module Configuration Definition
Dialog Box.
The following figure illustrates the concept of the communications buffer channels.
