| Bailey Infi90 Interface to the PI System 7 Introduction OSIsoft's Bailey Infi90 Interface program transfers data between the PI Server and a Bailey Network or a Bailey Infi90 distributed control system. The Interface runs on Windows NT version 4.0 SP, Windows 2000, Windows XP, and Windows 2003 Server computers. Unless otherwise noted, the remainder of this document uses the term "Windows" to refer to all these. An RS-232C serial cable provides the physical connection between the Windows computer running the Infi90 Interface and the Bailey control system. On the Windows side, the serial cable plugs into one of the standard COM ports. On the Bailey end, the serial cable is attached to a Network Computer Interface Unit (CIU) or the Infi90 ICI. Communications across the serial line occurs via a binary protocol. This protocol is defined in the Bailey publication Computer Interface Unit Programmer's Reference Manual (E. This protocol is based on exception reporting. That is, the CIU or ICI sends a value to the Infi90 Interface only when the value has met exception specifications. The communication parameters are 1200, 2400, 4800, 9600 orbits per second, 8 bits, 1 stop bit, and no parity. The Interface supports both the enhanced (CIU02, CIU03, CIU04) and CIU01 versions of the computer interface module as well as the serial version of the ICI01. For the enhanced CIU, the interface supports exception report screening. The ICI01 is compatible with the CIU04. Unless otherwise noted, the remainder of this document refers to the CIU and ICI computer gateways interchangeably. The Interface supports bidirectional data transfer. That is, the Interface supports reading values from the Bailey control system into the PI Server (i.e., inputs) as well as sending a value from the PI Server to the Bailey control system (i.e., outputs. The interface sends an output whenever the PI source point receives anew snapshot value. The Interface supports a failover configuration whereby a Primary copy of the interface collects data and a Secondary copy stands by in case primary data collection fails. Download 0.78 Mb.
