ACC-72EX User Manual

INTRODUCTION
This manual provides the information needed to configure ACC-72EX, a fieldbus/real-time Ethernet
interface for the Turbo or Power UMAC. The ACC-72EX is equipped with a “gateway” daughter card
that allows the UMAC (also referred to as host application) to send and receive data through the
supported fieldbus/real-time Ethernet protocols. The gateway used is the COMX CN series manufactured
by the Hilscher Corporation. Relevant hyperlinks are provided in Appendix D for in-depth information
regarding these modules.
There are three connectors located on the front of the ACC-72EX:
First, a Micro B USB connector, which is specified as “Diagnostic Port,” and provides USB connectivity
to Hilscher’s “SyCon.NET” software.
The second connector, which is referred to as the “Fieldbus Port”, is a 9-Pin Male D-Sub connector which
is used for connecting the fieldbus link to ACC-72EX. The fieldbus protocols supported through this port
are:
PROFIBUS-DP – Master – OPT10
PROFIBUS-DP – Slave – OPT11
DeviceNet – Master – OPT20
DeviceNet – Slave – OPT21
CANopen – Master – OPT30
CANopen – Slave – OPT31
CC-Link – Slave – OPT51
The third connector is composed of two RJ-45 ports which provide connection to real-time Ethernet
networks. The following real-time Ethernet protocols are supported through these ports:
EtherCAT – Master – OPT60
EtherCAT – Slave – OPT61
EtherNet/IP – Scanner/Master – OPT70
EtherNet/IP – Adaptor/Slave – OPT71
Open Modbus/TCP – OPT80
PROFINET IO – Controller – OPT90
PROFINET IO – Device – OPT91
The protocol is dependent upon the equipped COMX gateway. The hardware cannot be programmed for
an alternate protocol or change from slave to master or vice versa. However, should the COMX gateway
be replaced with one supporting another protocol, the baseboard would function properly as a
communications link to UMAC. In this case, proper jumper settings should be set up to ensure proper
functionality on communication lines and option detection.
Most gateway cards get their power from the UBUS back plane; however, the DeviceNet option (Options
3 & 4) requires an external 24 VDC power supply through the “Fieldbus Port.”
