OPC90 Server
• INICI03 sites containing INICT03A firmware revision ‘F’ must upgrade to
revision ‘G’ or later or downgrade to revision ‘E’.
• INICI13 is comprised of the INICT13A and INNIS01 modules. The default
factory settings for the INICT13A SW4 are incorrect. The INICT13A SW4
Poles 6, 7, 8 must be open (1) when using SCSI with this module.
Throughput of the supported devices is difficult to calculate empirically since the
data is received and sent by exception and varies according to the data type and
what has changed significantly at any given time. The exception reporting rate
per general data type for RS232 and SCSI interfaces is presented in the
following table:
Data Type RS232 @ 19.2k
values / second
SCSI
values / second
Analog 260 / 161* 1080 / 1059*
Digital 310 / 260* 1230 / 1206*
Control Loop 106 / 91* 618 / 606*
Average 225 / 170* 976 / 957*
* Rate when the device block “Use DCS Timestamp” option is
enabled.
Note that a few of the above mentioned devices do not support exception
reporting. Specifically the NSPM01, IMSPM01, IMCPM01 and IMCPM02. Data
collection from these devices is basically limited to the OPC90 Server blocks that
poll to get the block values. The names of these blocks are POLL, BLK and
SPEC. The remaining interfaces support the following OPC90 Server blocks and
associated Bailey exception report block types:
OPC90 Server Block Type Bailey Block Name F.C. Number
AIL Analog Output / Loop – AOL 30, 70, 158
BLK Bailey Block Configuration any function code
DAANG Data Acquisition Analog – DAANG 177
DADIG Data Acquisition Digital – DADIG 211
DD Device Driver – DD 123
DIL Digital Output / Loop – DOL 45
HAI Harmony Analog Input 222

Harmony Analog Output 223
HDI
Harmony Digital Input 224
HDO Harmony Digital Output 225
