HIMA X-SB 01985210207 24VDC System bus module

Product Description The X-SB 01 system bus module is intended for use in the programmable electronic systems (PES) HIMax. The module can only be inserted into base plate's slots 1 and 2. If the base plate only contains one module, the HIMax system operates with only one system bus (mono operation). If the base plate contains two modules, the HIMax system operates with two redundant system busses (redundant operation).   HIMA recommends using redundant operation (default) to exploit the HIMax system availability.

The module has the following functions: 

To establish connections between the modules. 

To establish connections to other base plates. 

Manage the rack ID and SRS of the modules.

Further, the module provides an interface to the programming and debugging tool (PADT). The module has been certified by the TÜV for safety-related applications up to SIL 3 (IEC 61508, IEC 61511 and IEC 62061), Cat. 4 (EN 954-1) and PL e (EN ISO 13849-1). Refer to the HIMax Safety Manual (HI 801 003 E) for more information on the standards used to test and certify the module and the HIMax system.

Safety Function 

 The module transfer the data via a safety-related protocol.

Reaction in the Event of a Fault If a failure occurs on a system bus, the bus connection is ensured via the redundant system bus, provided that both system busses have been previously configured.

Scope of Delivery The module must be installed on a suitable connector board to be able to operate. The connector boards for the system bus module are integrated into the base plate and are contained within the scope of delivery, see Chapter 3.6.

Type Label The type label specifies the following important details:   Product name Mark of conformity Bar code (2D or 1D code) Part number (Part-No.) Hardware revision index (HW Rev.) Software revision index (SW Rev.) Operating voltage (Power) Ex specifications (if applicable) Production year (Prod-Year:)

Structure 

The module consists of: Safety-related processor system Service and system bus interfaces

The module is equipped with LEDs to indicate the status, see Chapter 3.4.4. 

Block Diagram The following block diagram illustrates the structure of the module.

Safety-Related Processor System 

The safety-related 1oo2 processor system controls and monitors one system bus of the 

HIMax system. The X-SB 01 module in slot 1 controls and monitors the system bus A and 

the module in slot 2 controls and monitors the system bus B. 

Operating system and error code history are stored in a non-volatile memory which can be 

read in SILworX via the diagnosis.

Interfaces 

The connector board associated with the module is equipped with the following interfaces: 

One service interface (PADT) 

Two system bus interfaces (UP, DOWN) 

One diagnostic interface (DIAG), for future applications 

Service Interface PADT 

The service interface allows the user to connect to the PADT. The service interface can be 

used to load both the user program into the processor module and the operating system 

into the individual modules. 

Interfaces 

The connector board associated with the module is equipped with the following interfaces: 

One service interface (PADT) 

Two system bus interfaces (UP, DOWN) 

One diagnostic interface (DIAG), for future applications 

Service Interface PADT 

The service interface allows the user to connect to the PADT. The service interface can be 

used to load both the user program into the processor module and the operating system 

into the individual modules. 

The service interface does not support auto crossover. A crossover cable must be used for 

point-to-point connections. 

System Bus Interface UP, DOWN 

The system bus interfaces are used to connect to additional base plates in the HIMax 

system and are configured with the SILworX programming tool. To connect the interfaces, 

use cables complying with Ethernet megabit standard (at least CAT 5e cable).

System Bus Interface UP, DOWN The system bus interfaces are used to connect to additional base plates in the HIMax system and are configured with the SILworX programming tool. To connect the interfaces, use cables complying with Ethernet megabit standard (at least CAT 5e cable).

The LEDs indicate the operating state of the module. The LEDs on the module are divided into six groups: Module status indicators (Run, Error, Stop, Init) Redundancy indicators (Ess, Red) Rack connection indicators (Up, Down) Slot indicators (Slot 3…18) Diagnostic indicators (Diag) Communication indicators (Ethernet) When the supply voltage is switched on, a LED test is performed and all LEDs briefly flash simultaneously.

Redundancy Indicators The LEDs are located below the module status indicators.

Rack Connection Indicators The rack connection and slot LEDs are labeled Sys Bus.

Slot Indicators The slot indicator LEDs are located after the Slot label.

Diagnostic Indicators Diagnostic indicators reserved for future applications!

Ethernet Indicators The communication LEDs are labeled Ethernet.

Connector Boards The connector boards connect the system modules to the Ethernet interfaces. Two connector boards are secured to the base plate: one left connector board (L) for slot 1 and one right connector board (R) for slot 2. The connector boards contain information on the number of modules (10, 15 or 18) that can be inserted into the base plate and the corresponding slot IDs.

Pin Assignment The interface name is printed on the connector boards.
