RMSC Read (Bailey Point Type 19)


The conversion is the same as the other analog point types. (RMSC is function code 68.) The status of the analog value can be accessed through the following extended attributes:

4-byte Analog Read (Bailey Point Type 21)


It is handled like other analog point types except that the precision is higher (about 7 significant digits) and the range is larger (-3.4E38 to 3.4E38). The status of the analog value can be accessed through the following extended attributes:

4-byte Analog Report (Bailey Point Type 22)


This is one of the point types for sending data from the PI system to Infi90. 4-byte analog reports are processed in the same way as the 3-byte analog report (type 12) except that the 4-byte analog points have greater range and higher precision. They are in the range of -3.4E38 to 3.4E38.

DAANG (Bailey Point Type 29)


The data acquisition analog block has many attributes that may be of interest to the user. By default, the interface extracts the analog output value of the block into the PI value for PI tags with location 5 set to 29. To get the other attributes, use the extended descriptor keyword /BLY=x,y,etc. followed by the attributes code as described below:

String (Bailey Point Type 30)


For the Windows version of the interface talking to a PI 3 server, the user has the option of putting the string data to string tags or into the Event Logger. If the PI tag is of point type String, then the string data from Bailey will be put into the string tag directly, else the string data will be put into the PI Event logger. If the PI tag is configured as string type, the Bailey string is put into the PI tag without the prefix of time stamp, tag name and quality flag like the data going into the Event Logger. If the Bailey string has bad quality, the digital string “bad input” will be written to the PI string tag.
Since Bailey will transmit exception reports (on a rate) for the ASCII data even if it doesn’t change, the interface provides a rudimentary filtering function. The interface will send the data to the Event Logger or PI string tags only if the ASCII string or status of the related PI tag have changed.

MSDD (Bailey Point Type 51)


The multi-state device driver (Bailey function code 129) has many attributes that could be of interest to the user. By default, the interface extracts only the output field into the PI value for PI tags with location 5 set to 51. To get the other attributes, use the extended descriptor keyword /BLY=x,y,etc. followed by the attributes code as described below:
