3.4.7 Multifunction I/O used as serial communication interface
The Multifunction I/O can be set up as a serial communication interface.
When this configuration of the Multifunction I/O is selected, the A and B channels func-
tion as a receive and transmit channel via which commands to the MAC motor can be
transmitted from, for example, a PC or PLC.
This feature can be used in all modes of operation.
The communication protocol is described in the MAC motor Technical Reference Guide,
which must be requested separately and is not part of this user manual. See also
communication, page
The Multifunction I/O's must be set up in MacTalk to function as a serial communication
interface.
The serial com-
munication can
be used in all
