Turbo PMAC Family Overview
IOGATE I/O IC
The IOGATE IC is used to access general-purpose digital I/O on most of the UMAC I/O boards. It
provides 48 I/O points, addressed as 6 bytes in consecutive registers. Different boards use different
buffers and drivers around the IOGATE to provide the specific I/O features desired. While on the
IOGATE itself, each I/O point is individually selectable as to direction, on most of the I/O boards, each
point’s direction is fixed by the external circuitry for that point. The IOGATE must be set up at power-
on/reset to support the particular direction configuration of the board it is used on.

Potentially, up to 16 boards with the IOGATE or similar ICs can be installed in a UMAC system. The

Communications Ports
Turbo PMAC controllers provide multiple communications ports. These ports can be used
simultaneously, permitting the use of a second port for debugging while the primary port is used in the
actual application, or of a second port for an operator pendant.

Bus Ports
Each configuration of the Turbo PMAC supports a bus port for fast parallel communications. These
utilize the host port on the DSP, and optionally dual-ported RAM for communications through shared
memory. The buses can be either the traditional backplane buses, or the newer wire buses.
The backplane buses currently supported are:

The backplane buses currently supported are:
•
ISA (or the PC/104 stack version)
•
PCI
•
VME
The wire buses currently supported are:
•
USB (1.1 or 2.0)
•
Ethernet (TCP/IP or UDP/IP protocols) at 10 Mbps
Serial Ports
Turbo PMACs also support serial-port communications, always with a single serial port, optionally with a
second serial port as well.
second serial port as well.
Main Serial Port
Turbo PMAC controllers always come with a standard serial communications port. In most
configurations, this port can be used with either RS-232 signal format, or RS-422 signal format, jumper
selectable. Even if there are separate connectors for the two signal formats, this is a single port; only one
of the connectors can be used at a time.

Optional Auxiliary Serial Port
If the Option 9T is ordered, a second serial port, always at RS-232 levels, is provided. This port can be
used for general communications. It is possible to turn off the command parser for this port by setting
variable I43 to 1, so Turbo PMAC does not try to interpret incoming characters as commands, making it
possible for the user to parse incoming data as he pleases. This port is required for setup and diagnostics
if the IEC-1131 PMAC Ladder programs are used.
