The Yokogawa YGW interface provides communication between PI and Yokogawa CGWU, EGCW3 and ECGW* gateways and the Micro XL DCS. It is an OSI Software standard Universal Interface (Uniint).
Note: All mention of the above four Yokogawa systems will be referred to, hereafter in this manual, as “the gateway”. If, however, information in this manual refers to a specific gateway, the actual gateway name will be used.
Data is transferred between the gateway and the interface via RS-232 Serial TTY communication or TC/PIP socket calls. Data is transferred between the interface and PI via the PI API. The PI API is necessary for the interface to run and is not included with the interface. The minimum requirements for the interface are given in the following table:
Intel Windows NT
Alpha Windows NT
The interface supports input tags (from Yokogawa to PI) and output tags (from PI to Yokogawa). It counts the events to and from these tags, including exception tests, and sends its totals periodically to PI. Data from the gateway is received at cyclic frequencies or by exception in the data. The frequency of the cycles is configured by the user and controlled by the interface. The number of tags that the interface is capable of servicing is unlimited.
Changes that are made to the PI point database are reflected in the interface. This includes the adding, editing and deleting of tags.
All error information and some summary information are output to a log file. The amount of summary information that is output is configurable by the user and is minimal by default. For information about configuring information messages, see the “/db”, “/lg” and “/cl” headings of the Interface Startup File section on page 15.
A summary of the features of the interface is shown in the following table:
