	Command Reference

`bufferUpdateGroups`

bufferUpdateGroups — triggers an I/O cycle of buffers and point groups.

Synopsis

       
(bufferUpdateGroups [card_id [update_mode]])

Parameters

card_id: An optional card ID. If not specified, the command is applied to all available cards.
update_mode: This parameter is entirely card dependent.

Returns

OK if successful, or one of the following errors:

(error "bufferUpdate DR_ERR_CARD_INVALID (time) invalid card: card_id")

(error "bufferUpdate DR_ERR_CARD_IO_FAILURE (time) I/O failure (error_code) on device card_id")

(error "bufferUpdate -1 (time) Command invalid: Card card_id using interrupt mode")

Description

This command triggers an I/O cycle of the buffers and point groups. It is identical to the bufferUpdate command, except that in addition, the output group points are first scanned to update the data and, after the buffer data transfer, the input group points are scanned for updated values. This command is typically sent as a command and not used in configuration file.
