ACC-36E Manual

USING ACC-36E WITH UMAC MACRO 47

Transferring Data over I/O Nodes

The following explains the ADC data transfer from the $020X to $C0XX registers, and suggests user

M-Variables for direct access.

It is assumed that the ADC processing has already been configured as explained in the previous step, and

that the data is readily available in the $020X registers. Also, it is assumed that communication over the

MACRO ring has already been established, and that the user is familiar with node activation on both the

Ring Controller and MACRO Station. Thus, any node(s) used in the following examples have to be

enabled properly.

Having multiple cards of different types on the MACRO Station can make the I/O transfer management

cumbersome. Therefore, two alternative methods are suggested:

 Automatic I/O node transfer, using MS{anynode},MI173, MI174, and MI175

This method is ideal for up to 2 ACC-36Es in one station.

 Manual I/O node transfer using MS{anynode}, MI20 through MI68.

This method is recommended when more than two ACC-36E cards are present and/or

there are other types of cards requiring a large amount of data transfer over I/O nodes.

Note that this method can be used in conjunction with the automatic transfers.

Note

This section assumes that MACRO ring, I/O nodes, and ring check

error settings have been configured properly.
