– Brick MACRO I/O Data Transfer
This section describes the handling of inputs and outputs data transfer over the MACRO ring. That is
transferring I/O data from the Brick slave to the Brick master.
A Geo Brick Drive, used as a MACRO slave, can be populated with up to:
transferring I/O data from the Brick slave to the Brick master.
A Geo Brick Drive, used as a MACRO slave, can be populated with up to:
32 digital inputs / 16 digital outputs (connectors J6, J7)
4 x 12-bit filtered PWM DAC outputs (connectors X9, X10, X11, X 12)
4 x 16-bit analog inputs (connectors X9, X10, X11, X 12)
8 x 12-bit analog inputs (connector J9)
There is a variety of ways to transfer I/O data over MACRO:
Using I/O nodes.
This method consists of assembling the data in a PLC code at the slave side, and conveying it
over to MACRO I/O nodes. These I/O nodes are then extracted in a PLC code on the master side
and placed into open memory registers. This technique is suitable for digital inputs and outputs.

Using servo nodes
This method is primarily used for the X9-X12 analog inputs and outputs which, in some
applications, may require being processed at servo or phase rate (e.g. servo feedback, cascaded
loop or output to a spindle drive). This is the fastest transfer method possible. Note that in this
mode, axes 5-8 on the slave cannot be configured to drive motors. The corresponding servo nodes
will be occupied.

Using MACRO Auxiliary MX reads and writes in a background PLC
This method is ideal for transferring a large amount of data without much coding and complexity.
It is suitable for monitoring and toggling inputs and outputs. But it is not deterministic (relies on
background PLCs, and phase cycle delays with MX commands) or as fast as other methods.
