1 General Specifications GS 32P03B25-01EN Model RS4F1170 Safety Control Function (for SSC57 ) GENERAL Safety Control Function is a software package that works on a Safety Control Station (SCS). (*1) The Safety Control Function is to monitor a plant and ensure its safe operation. This software package performs preset safety operations whenever safety control is required. RS4F1170 Safety Control Function (for SSC57 ) is applied to SSC57 Safety Control Unit (for Vnet/IP-Upstream, FIO, Rack Mountable Type). The test functions can be performed by using RS4F1170. Vnet/IP-Upstream is a control network integrating ProSafe-RS and FAST/TOOLS. For more details, refer to the GS ProSafe-RS Safety Instrumented System Overview (for Vnet/IP-Upstream) (GS 32P01B30-01EN). *1: The SCS is composed of a safety control unit and safety node units. FUNCTIONAL SPECIFICATIONS The following describes the configuration and functions of the package are described as follows: Configuration of RS4F1170 Safety Control Function The functions of the package can be divided into two groups: one is an application logic execution functions group and the other is an external connection functions group.

The RS4F1170 supports the data buffering function and the gas flow calculation function, that both are needed for the systems used for upstream applications. (*1) These functions are interference-free. The following functions compose of the main part of the package that monitors the plant and ensures its safe operation, and performs preset safety operations once an abnormality occus. Application logic execution function Process data I/O function Communication data I/O function (Subsystem communication function) Inter-SCS safety communication function SCS link transmission function Self-diagnosis function *1: The RS4F1170 s gas flow calculation function is in accordance with the AGA (American Gas Association) specification; however, RS4F1170 does not support custody transfer application. For the gas flow calculation for custody transfer, use the STARDOM network-based control system.

9 9 Modbus Communication Function The SCS communicates with external equipment such as sequencers via the Modbus protocol. The SCS acts as the Modbus master which enables to read and write external equipment data. The external equipment also acts as the Modbus master which enables to read and write the SCS data. Connecting with the Modbus communication module is interference-free. ALR121 serial communication module supports ProSafe-SLS communication function which extends the Modbus communication function. For more details, refer to the GS ALR111/ALR121 Serial Communication Module (GS 32P06K50-01EN) or ALE111 Ethernet Communication Module (GS 32P06K51-01EN). Modbus communication function SCS acts as a Modbus master SCS acts as a Modbus slave Communication module Serial communication module X X Ethernet communication module X X X: Supported DNP3 Slave Function SCS can communicate with DNP3 master with DNP3 protocol via an Ethernet communication module (ALE111). The external equipment acts as the DNP3 master and can read and write the SCS data. Refer to the GS ALE111 Ethernet Communication Module (GS 32P06K51-01EN) for more details. The DNP3 slave function is interference-free. Sequence of Events Recorder (SOER) Function The SOER function is composed of event collection sub-function, event storage sub-function, and time synchronization sub-functions. The HMI can display event information when an SOE viewer package is resided in the HMI computer of FAST/TOOLS. Event collection and storage sub-function Event information is collected and stored in a digital input module or a CPU module of an SCS. Time stamp resolution of events collected by a digital input module is 1 ms. Other events are collected by a CPU module by the SCS s scan period as the time stamp resolution. Objective event information The SCSs collects the following event information when defined by the user definition. Information to be collected Digital input Digital output Analog input Application logic variable Trigger for event collection and location for collection Changes in the data value input into the digital input module trigger to collect events. The SOE collection can be enabled or disabled by the channel. (*1) (*3) Changes in the data value output to the digital output module trigger CPU to collect events. The SOE collection can be enabled or disabled by the channel. (*2) (*3) The analog input function block determines the level of the data value to collect events. (*4) Each of the SOE event collection function blocks for BOOL-type, INTEGER-type, and REAL-type collects events. (*4) *1: When the digital input module is dual-redundant, the module with control authority collects events. *2: When the status of output channel is abnormal (the data status is BAD), no events are collected. *3: Channel comments (a string composed of a maximum of 32 single-byte characters or 16 double-byte characters) needs to be defined. *4: A sequential event identifier (a string composed of maximum of 32 single-byte characters or 16 double-byte characters) needs to be defined for the input terminal ID of a function block. Analog output events are to be collected by a function block for SOE event collection for constants. Storage of Event Information Event information is stored in an event information file in an SCS. Such event information can be seen from multiple SOE viewers. Two kinds of event information files are provided an event log file and a trip signal file. The event log file contains collected event data. The trip signal file contains events before and after a trip signal specified by a user. Table Event Information File Specification Event log file (*1) Trip signal file (*2)(*3) Number of events Max events Max events (500 before signal generation and 1000 after signal generation) Number of files Max. 1 Max. 2 *1: A diagnosis information message is sent to the user at occurrence of every events. *2: Upon completion of collecting trip signal file, a diagnosis information message is sent to a user. *3: In case the number of events does not reach 1000 in 30 minutes after the trip signal is generated, a trip signal file creation is terminated and a diagnosis information message is sent to a user. GS 32P03B25-01EN Apr. 26,

10 10 Diagnosis Information Collection Function An SCS sends a diagnosis information message when an abnormal condition is detected, and the message is stored in the memory of the SCS as the diagnostic information. The message contains the time, location, type, and other information of the abnormality. The SCS can store up to 5000 pieces of information. PRM-supported HART On-demand Communication On-demand communication with a HART device is implemented by Plant Resource Manager (PRM) which sends a HART command, and then receives a response from the HART device via the SCS. Analog input/output modules with HART function (SAI143-H and SAI533-H) serve as communication relays. Test Function The test function supports performance tests of the user-made applications. Two test modes are available: target test employs the actual systems in operation and logic simulation test uses the logic simulator.
