1. The following are comments w.r.t FAT procedure a. PDIL approved FAT procedure procedure mentions demonstration of PLC scan time. Since actual I/O allocation for various tag and instrument type is yet to be completed. Hence DCS /TAS PLC/ Safety PLC scan time not checked. Feature is available in Control builder with the option to select the tasks as normal, slow and fast depending upon the scan rate. CPU loading also not checked as all I/O mapping and corresponding scan time and logic is yet to be implemented. b. Comments on FAT procedure mentions - TFM to DCS communicate test. Presently OEM software is not loaded in TFMS server. Mapping of tag between TFMS to DCS not done as CIU (FCU of Emerson) shall be installed at site. Also graphic for Tank farm yet to be developed, Hence TFM to DCS communication not checked. c.
Continuity from TB to Isolator/relay to Input/ out card to controller to work station mapping (Control builder table) for Analog Input/ Output, Digital input/ Output checked. Since actual I/O allocation for various tag and instrument type is yet to be completed for each channel, hence Dynamic Checks on Application Software not checked.
d. Since P&I graphic and I/O database configuration is yet to be done , hence the following checks not demonstrated Simulation, graphics functionality functionalit y Description/Range/Units/Alar Descriptio n/Range/Units/Alarm m Limits of various instruments Digital symbol shall colour change in accordance with their simulated state Logic check, PID tuning parameters.
ESD applications are to be programmed using SIL3 complaint libraries.
e. System alarms and events checked on Engineering / Operator station - Process Process alarm & process event not verified.
2. Various features of TAS software demonstrated. ABB to built-in Project specific loading operation philosophy applicable for LPG loading along with weigh bridge sequence. 3. Terminal Server dual host communication redundancy checked and found O.K.. Terminal server serial port redundancy not checked. 4. Typical communication interface of Accuload III. Net Batch controller via non project specific terminal server to TAS software was checked and found O.K. Integration of batch controller with project specific Terminal server not checked 5. Gas detector in FGS panel and Jetty Panel – Presently wiring is for two wire through IS barrier. Since all gas detector are three wire i.e. 4-20 mA + 24 V source, hence necessary 24 V DC source along with TB arrangement to be made in the corresponding marshaling cabinet.
6. Networking panel – Proper dressing to be done. Horizontal cable duct to be provided for laying Serial communication cable to Terminal server. Also Vertical cable ducts to be provided for laying Ethernet and serial communication cable. 7. ABB to furnish Internal acceptance test report by the testing department personnel. Including all TC with serial no. for controllers, I/O cards 8. LIU to be mounted in SPLC-SC-01 panel. 9. Hardwire wired alarm annunciator panel and power distribution cabinet not offered for inspection.
