1 Overview

Features and Functions

The SIMATICr 505 PROFIBUS-DP Remote Base Controller (RBC), PPX:505–6870, allows a Series 505t I/O base to function as a slave node on a DP I/O channel that complies with the PROFIBUS standard (DIN 19245, Part 3). The SIMATIC 500 PROFIBUS-DP Remote Base Controller (RBC), PPX:500–6870, allows a Series 500t I/O base to function as a slave node on a DP I/O channel that complies with the PROFIBUS standard.

The 505 and 500 PROFIBUS-DP RBCs offer the following features:

• The RBC is compatible with Siemens S5t and S7t, as well as Series 505, masters.

• The 505 RBC can be used in all currently-available Series 505 bases (4-, 8-, 11-, and 16-slot models).

• The 500 RBC can be used in all Series 500 bases (6-, 12-, and 14-slot models, or original 8- and 16-slot models with PPX:500–5840 adapter).

• The RBC supports communication speeds from 9.6 Kbaud (maximum cable distance per segment: 1200 m) up to 12 Mbaud (maximum cable distance per segment: 100 m).

• The LED display shows error codes or current station address.

• A serial port is available for remote programming of the CPU when the

RBC is used on a Series 505/500 system.

RBC Specifications

• The RBC has a field-upgradeable operating system that is stored in flash memory.

• The base where the RBC resides can contain only modules that look like discrete or analog I/O; Special Function modules like Peerlink or NIMs are not supported.

• CPU commands received from the serial port are restricted to those that cannot alter the PROFIBUS-DP I/O configuration.

• A “GSD” file is provided with the RBC to allow configuration by the COM PROFIBUS configuration utility.

Figure 1 illustrates how the 505 and 500 PROFIBUS-DP RBCs fit into the I/O architecture of a Series 505 system.

The physical and environmental specifications for the 505 PROFIBUS-DP RBC are listed in the SIMATIC 545/555/575 System Manual.

3 RBC Ports

The 505 and 500 PROFIBUS-DP RBCs have two communication ports, an RS-232 port and a PROFIBUS-DP I/O channel port.

RS-232 Port

When used with a Series 505 CPU, the RS-232 port is an interface to programming devices that use software like TISOFT or other configuration tools. To connect your RBC to a programming device/modem, use a standard 9-pin RS-232 serial cable that conforms at a minimum to the pinouts shown in Figure 4. A standard cable that conforms to the minimum requirements is available through Siemens; specify part number 2601094–8001.

PROFIBUS-DP Port

The PROFIBUS-DP port is used to connect the RBC to the PROFIBUS-DP I/O channel. The SIMATIC 545/555/575 System Manual describes how to connect a 12 Mbaud RS-485 cable to the PROFIBUS-DP port. Figure 6 shows the pinout for the PROFIBUS-DP port for the PROFIBUS-DP RBC.

NOTE: Pins 2 and 7 are “No Connect” for the RBC. For some PROFIBUS products, these pins are used to provide 24 VDC for powering a programming or configuration tool. Such tools are not powered by the RBC; however, it is acceptable for an externally-powered PROFIBUS programming or configuration tool to drive pins 2 and 7 to 24 VDC.

Pin 5 (BIAS SUPPLY +5V) and Pin 6 (BIAS SUPPLY GND) on the PROFIBUS-DP connector are designed to support the PROFIBUS-DP I/O channel only. These pins have a limited output power capability of approximately 0.45 W, which greatly exceeds the typical PROFIBUS-DP load; however, overloading these pins may cause internal component damage.

If the pins are overloaded, the PROFIBUS-DP port can be rendered non-functional, requiring the unit to be returned to the factory for repair.

Do not overload the pins on the PROFIBUS-DP connector.

4 Output State Selection on the RBC

Selecting Output State (Off/Freeze) on the 505 RBC

When I/O channel communication to a Series 505 base is lost, the state of the outputs is determined by the selection made on the 505 RBC jumper E1 (Off/Freeze). Figure 7 shows the location of the jumpers on the 505 RBC.

NOTE: You must make an E1 jumper selection on the 505 RBC. The RBC Status Display reports an error if no jumper selection is made.

The jumpers on the 505 RBC headers E2 and E3 are for factory use only. Header E4 is shipped without a jumper. Do not alter the default settings unless instructed to do so by a Siemens Technical Support technician.

Output State Selection on the RBC (continued)

Determining Discrete Output State

Determining Analog Output State

For discrete output modules, the state of the outputs is determined solely by the position of the Off/Freeze jumper E1 on the 505 RBC or the Off/Freeze switch on the 500 RBC.

For analog/word output modules, the state of the outputs is influenced not only by the position of the Off/Freeze switch but by the output module’s (Zero/Hold Last Value) selection, if the module has that option. See Table 1.

Table 1 Analog/Word Output States

RBC Off/Freeze Selection

Off Zero Zero* Off Hold Last Value Last Value

Off – no selection – Last Value Freeze Zero Last Value Freeze Hold Last Value Last Value Freeze – no selection – Last Value

*See the user manual of your analog/word output module for further details.

Analog/Word Module

Zero/Hold Selection

Analog/Word Output State

Notice, in Table 1, that the Freeze option on the RBC overrides the Zero selection on the analog/word output module; likewise, when Hold Last Value is selected on the analog/word output module, that selection overrides the Off option on the RBC jumper.

NOTE: If the RBC hardware watchdog timer is activated (by an RBC

failure), the state of the outputs is determined by the output module, with no reference to the RBC’s Off/Freeze setting. Discrete outputs go off (to a value of zero). Analog/word outputs obey their own Zero/Hold Last Value selection. If no Zero/Hold Last Value selection is available on the module, the analog/word outputs hold their last value.

Baud Rate for the RS-232 Port

Switches 1 through 3 on the dipswitch control the baud rate of the RS-232/423 port. Table 2 lists the baud rates available.

Invalid selections cause the RBC to report an error on the Status Display and cause the RS-232/423 port to default to 9600 baud.

The RS-232/423 baud rate switch settings are read only on power-up or after pressing the reset button.

NOTE: The RS-232 port is disabled by default. To enable the port, change the default parameter of the module in COM PROFIBUS. (See Table 5.)

9600 1 1 0 2400 1 0 0 1200 0 1 0

300 0 0 0 INVALID 0 1 1 INVALID 1 0 1

Assigning the RBC Station Address

Switches 4 through 10 on the dipswitch are used to assign a station address to the RBC for identification in the PROFIBUS-DP I/O channel. Each station in the PROFIBUS-DP I/O channel must be uniquely numbered. The station address is assigned as a binary number, with SW10 as the Least Significant Bit (LSB). Table 3 shows how to set the dipswitch to a station address between 0 and 125 (the valid range of station addresses).

The station address switch settings are read only on power-up or after pressing the reset button.

Pressing the RESET button when the system is operating causes the RBC to be logged off the system and may change the output states of the output modules in the base. Inadvertently logging the RBC off the system or changing output states can cause unpredictable process operation.

Unpredictable process operation can result in death or serious injury to personnel, and/or damage to equipment.

Do not push the reset button unless you intend to log the RBC off the system.

Dipswitch Options (continued)

Reset Pushbutton

Resetting the RBC

The RESET pushbutton on the front of the RBC is deliberately recessed to prevent accidental activation. When you press this button, a global reset is immediately performed on the RBC. After completing reset, the RBC assumes the RS-232 baud rate stipulated by the setting of switches 1 through 3 on the dipswitch, and the station address indicated by switches 4 through 10.

WARNING

Pressing the RESET button when the system is operating causes the RBC to be logged off the system. When the RBC is logged off, inputs and outputs associated with the base are affected. See the documentation for your system master to find out how the master handles I/O when the RBC logs off. If you do not take the condition of your inputs and outputs into account, logging the RBC off the system can cause unpredictable process operation.

Unpredictable process operation can cause death or serious injury to personnel, and/or damage to equipment.

Do not reset your RBC unless you understand and are prepared for the consequences.

The following actions take place when an RBC is reset.

• The CPU logs the RBC off the system and sets the image register points which represent the inputs from this RBC’s base to zero. The image register is zeroed out until the RBC completes reset and resumes communication with the CPU. If this occurs while the system is operating, depending on your RLL program, turning these inputs off could affect other base outputs.

• From the assertion of reset until the RBC completes the reset and resumes communication with the CPU, the state of the outputs on this RBC’s base is determined by the output module, with no reference to the RBC’s Off/Freeze setting. Discrete outputs go off (to a value of zero). Analog/word outputs obey their own Zero/Hold Last Value selection. If no Zero/Hold Last Value selection is available on the module, the analog/word outputs hold their last value.

• If the station address you assign to the RBC (by setting the dipswitch) inadvertently duplicates an address already in use by another slave on the I/O channel, then when the RBC completes its reset and attempts to communicate, identifying itself with the new station address, the other slave may be logged off the system. Intermittent operation could occur as long as the two slaves are set to the same station address.

SIMATIC 505/500 PROFIBUS-DP RBC User Manual

Page 21

When the CPU logs an RBC off the system, it sets a corresponding bit in one of the status words that are available to your RLL program. Your RLL program can use these bits to detect the loss of the RBC and control the outputs of other bases as appropriate for your application. For details about status words and more information about programming, refer to the SIMATIC 545/555/575 Programming Reference User Manual.

Dipswitch Options (continued)

Status Display Mode

Switch 11 on the dipswitch controls the display mode of the RBC Status Display to show either station address or module status.

• When switch 11 is set to 1, the station address of the RBC is displayed as a three-digit number, one digit at a time. The display goes blank for a short period of time between each digit and for a long period after the last digit. For example, if the RBC station address is 18, it will be displayed according to this pattern:

0 (short pause) → 1 (short pause) → 8 (long pause) 0 (short pause) → 1 (short pause) → 8 (long pause) . . .

The three-digit pattern repeats until the mode is changed.

• When switch 11 is set to 0, the status of the RBC is displayed, according to the codes shown in Table 4.

NOTE: When switch 11 is set to display the RBC status, a decimal point on the status display indicates that the 50X Ignore Mismatch Mode parameter is enabled. The point appears before the status code, as shown below.

If the 50X Ignore Mismatch Mode is disabled (the default value that conforms to the DP standard), the RBC status display does not show a decimal point. For more information about this parameter , see page 20.

The Status Display mode switch is read periodically during operation. The switch may be changed at any time.

6 Parameters Set by Software

Setting User Parameters for the PROFIBUS-DP RBC

The PROFIBUS-DP RBC has parameters that are specified using the COM PROFIBUS configuration utility software. Refer to the SIMATIC 505

TISOFT2 User Manual and the SIMATIC S5 ET 200 Distributed I/O System Manual for information about using COM PROFIBUS.

Table 5 describes the parameters used to set up the 505/500 PROFIBUS-DP RBC in COM PROFIBUS. You set these parameters by selecting the “Parameterize” dialog box in COM PROFIBUS.

Discrete I/O Interval

Word I/O Update Factor

50X Ignore Mismatch Mode

50X RS-232 Comm Port

The Discrete I/O Interval parameter defines the rate at which the PROFIBUS-DP RBC updates I/O modules. This parameter specifies the minimum time between updates of the discrete I/O modules.

The Word I/O Update Factor controls how often the word I/O modules are updated. The Word I/O Factor is the number of discrete I/O updates performed per word update; for example, if the factor is 2, the word I/O modules are updated on every second discrete I/O update.

The 50X Ignore Mismatch Mode parameter allows you to select the way I/O configuration mismatches are handled. With the default setting, “Disable,” the PROFIBUS-DP RBC handles I/O configuration mismatches according to DP Standard mode, meaning that the configuration sent by the CPU to the RBC must match the actual base configuration exactly, or else no I/O updates are performed. If you enable 50X Ignore Mismatch Mode, the RBC performs updates with all modules whose configuration matches, omitting only those modules whose configuration does not match. This mode of operation does not conform to the DP Standard.

The default for RS-232 port communications is communications disabled. When 50X RS-232 Comm Port is enabled, the RBC is not operating in 100% compliance with the PROFIBUS-DP Standard due to the additional network traffic caused by task code transfers.

7 Diagnostic Data Reported by the RBC

PROFIBUS-DP Diagnostic Bytes

Byte 1: Station_Status_1

The standard for PROFIBUS-DP I/O, DIN 19245, Part 3, stipulates the format that each DP slave shall use to report specific diagnostics to the DP master. The diagnostics used by the 505/500 PROFIBUS-DP RBCs are described below.

NOTE: Byte 1 through Byte 15, as described in this text, correspond to Octet 1 through Octet 15 in the PROFIBUS standard. For PROFIBUS-DP I/O, Bit 7 is the most significant bit (MSB), 0 is the least significant bit (LSB). This may or may not correspond to the bit numbering scheme used in your master system. For example, Series 505/500 controllers identify the MSB of a byte as Bit 1, and the LSB of a byte as Bit 8.

A DP diagnostic consists of two parts. The first part (Bytes 1 through 6) is standardized for all DP slaves. The second, or extended, part (Bytes 7 through 15 in the case of the RBC) is slave-specific. In the description that follows, it is assumed that the diagnostic has been successfully read from an RBC that has been configured and activated: that is, that Bytes 5 and 6 equal 0xBC and 0xD0, respectively.

MSB LSB

01234567

8 Upgrading the Operating System

Overview

The operating system of the 505/500 PROFIBUS-DP RBC is contained in user-programmable non-volatile memory. An RBC with a previous release of the operating system can be reprogrammed with the latest release. You need a PC and a standard cable in order to reprogram the RBC.

Contact the Technical Services Group for the appropriate upgrade files if you need to upgrade your RBC.

The operating system firmware for the RBC is supplied in a file called DPRBC.DLD. You use the RBCDL.EXE program to download operating system firmware from a binary file on the PC to the flash memory of the RBC.

SIMATIC 505/500 PROFIBUS-DP RBC User Manual

Page 31

Download Instructions

To download the new operating system firmware and locally program your PROFIBUS-DP RBC, follow the steps below:

1. Ensure that your process is in a safe state before you begin to download the new operating system firmware; I/O communication is temporarily interrupted by the downloading procedure.

2. Connect your computer to the RBC with a standard 9-pin RS-232/423 null modem serial cable. This cable is available through your Siemens Energy & Automation, Inc., distributor: ask for SIMATIC 545/555 Programming Cable, part number 2601094–8001.

3. Connect one end of the cable to the appropriate 9-pin RS-232/423 serial port on your computer, and connect the other end to the RS-232 port on the RBC. For the 500 RBC, use the same cable with a 9-to-25-pin male adapter.

If your computer does not have a 9-pin port, use a 25-to-9-pin converter.

NOTE: If your AUTOEXEC.BAT or CONFIG.SYS files are programmed to load a driver, such as a mouse driver, to the port that you wish to use, communications with the RBC will not be successful. Be sure that neither your AUTOEXEC.BA T nor your CONFIG.SYS file is programmed to load a driver to the port.

4. Verify that the RBCDL.EXE file and the DPRBC.DLD file are in the current MS-DOS directory. Make sure that the base that contains the PROFIBUS-DP RBC is turned on.

5. At the MS-DOS prompt, type in the download command, specifying the PC port number (namely, 1 or 2) that is appropriate for your PC configuration, and then press Enter.

For example, if your port number is 2, type the following text:

RBCDL DPRBC.DLD 2

and then press

SIMATIC 505/500 PROFIBUS-DP RBC User Manual

Enter .

Page 32

Upgrading the Operating System (continued)

6. T wo information prompts appear. Answer Y to continue the download, or

N to abort the download.

7. Immediately after you answer the second prompt with

Y, depress the

RBC reset pushbutton. This resets the RBC and begins the transfer to the new operating system that you are downloading.

WARNING

Pressing the reset button when the system is operating causes the RBC to be logged off the system and may change the output states of the output modules in the base. Inadvertently logging the RBC off the system or changing output states can cause unpredictable process operation.

Unpredictable process operation can cause death or serious injury to personnel, and/or damage to equipment.

Do not reset your RBC unless you are prepared for the consequence of disrupting I/O communication.

NOTE: The download of the operating system firmware takes approximately 2 minutes to complete. The RBC LED blinks, and Percent Complete displays on the PC.

When the download is complete, the RBC automatically reboots itself and is ready to communicate.
