Product Introduction
This manual provides the information needed to configure a fieldbus interface for the UMAC. The ACC72E is equipped with a “gateway” daughter card that allows the UMAC to send and receive data through the supported fieldbus protocol. The gateway used is the COM series, provided by the Hilscher Corporation. Relevant hyperlinks are provided in Appendix C for in-depth information regarding these modules.
There are two connectors located on the front of the ACC-72E. For Profibus, DeviceNET, CANopen and ControlNET options a male DB9 connector is specified as the Diagnostic Connector and provides a RS232 link for the SyCon software. The second connector is referred to as the fieldbus connector as it provides a means to become connected to the fieldbus link. The form factor of this connection is dependent on which fieldbus protocol is being utilized. For the Control & Communication Link (CCLink) option, the first connector is 10 pin IDC male header which provides a RS232 link for communication with the Compro software. The second connector is the 5 pin Combicon male connector which is the fieldbus link.
The protocol is dependent upon the equipped COM gateway. The hardware cannot be programmed for an alternate protocol including master/slave. However, should the COM gateway be replaced with one supporting another protocol, the baseboard would function properly as a communications link to UMAC although the fieldbus connector might be incorrect for the new fieldbus.
Most gateway cards get their power from the UBUS back plane. However, the DeviceNet version (Options 3 & 4) require an external 24Vdc power supply for the fieldbus.
