WARNING

Introduction

1.2 Outline description

Edwards take no responsibility for damage or injury caused by improper use of the equipment.

This equipment provides remote control of an Edwards pump. You must refer to the safety information in the pump instruction manual.

This unit should not be relied upon for safety related functions.

The GXS and CXS Profibus Module provides a Profibus DP V0 slave interface for Ed wards GXS and CXS pumps. The module communicates with the pump using the RS232 interface. Commands received from the Profibus network are relayed to the pump. Data from the pump is stored in the module and transmitted over the Profibus network when requested. The pumps provide the DC power for the module. The front panel of the module has four LEDs which indicate the status of the module and the Profibus network. The Profibus slave address is set using rotary switches. The back panel of the module has a 9-way 'D' connector for the Profibus network, a 9-way 'D' connector for the RS232 link to the pump and a power connector.

D397-53-880 Issue C

WARNING

Installation

3.3 Fitting the module to a CXS pump

To fit the module to the CXS pump, contact Edwards.

3.4 Electrical connections

When installing the module ensure that the cables are laid out and secured in a manner that will not create a trip hazard.

The Profibus module should not be connected to a pump when the pump or tool are "On Process". The Profibus Module uses the pump's rear (system) PDT port (a 5-way XLR socket) for communication w ith the pump.

It is not possible to connect any other devices to the same PDT port when that port is used by the Profibus Module, for example a PDT.

If the pump has several accessories at tached, guidance should be so ught from Edward s to ensure the pump is ab le to provide enough power.

Use the cable provided in the kit to connect the 9-way D-type free socket and the DC power connector to the Profibus module. Connect the 5-way XLR plug to the pump rear (system) PDT port.

Figure 5 - Profibus module rear connections

3.5 Profibus network connection

Standard Profibus network cables and connectors compliant to EN50170 should be used to connect the Edwards Profibus Module to your system.

Bus-termination is not supplied with the module, but must be used as for a normal Profibus DP system. Bus termination must be used at both end s of th e Prof ibus tr unk and not anywhere else. If the module is placed at one end of the trunk a connector containing the standard termination resistors should be used. The appropriate 5 V and 0 V signals are supplied on the standard pins for this purpose.

4 Operation

4.1 Profibus system information

The Profibus module is for connection to a Profibus DP network and operates as a V0 slave only. The Profibus master requires a GSD file for each slave. The GSD file for this slave is contained on the CD supplied

with the unit and has the file name "EDW0C5F.GSD", which is registered with the Profibus Association. When configuring your system the "ID" number will be 0C5F and the unit's description will be “Edwards_GXS/

CXS_Pump”.

Note: The GSD file should not be altered.

4.2 Quick start set up instructions

1. Install the module and connect the cables as described in Section 3.

2. Set the address switches on the Profibus module. See Section 4.4.

3. Apply power (or power cycle the Profibus Module, for example by disconnecting then reconnecting the power connector).

Operation

4. Load the GSD file into your Profibus system configurator.

5. Select "Edwards_GXS/CXS_Pump" as a slave and set the address to match the address switches.

6. Select Module 11 to provide on and off control of the pump and select Module 992 to monitor pump alert state. Add other Profibus software modules as required.

4.5 Baud-rate

All 10 standard DP baud-rates are supported. These are: 9.6kBd; 19.2kBd; 45.45kBd; 93.75kBd; 187.5kBd; 500kBd;

1.5MBd; 3MBd; 6MBd; 12MBd. The unit has no facility for adjusting baud-rate as detection is automatic, and it will therefore respond to the baud-rate chosen by the master.

4.6 Software format

The Slave software is based upon a modular configurab le architecture so the us er has considerable cont rol of the contents of the Data exchange messages.

The software modules (defined in the GSD files) relate to the controller serial communications objects. When the unit is linked onto the Profibus it will be parameterised and then configured before entering data exchange.

The configuration choices ar e in the GSD file and it s comments describe th e data content of the input and output bytes. These choices will often be made using a third party configurator such as SyCon that presents a user-friendlier interface.

16-bit values are transmitted with the MSB first and the LSB last.

4.6.1 Parameterisation

Only the Profibus mandatory 7 byte s of parameteris ation data are use d by the pump Profibus slave. None of these values can be adjusted by the user.

4.6.2 Configuration

During configuration the user can define what modules are required and in which order the data is transferred. The unit adds the input and output data bytes to the message maps in the order that they are de fined in the configuration message.

Example: Module = Mod_A 3 bytes in (Ai1, Ai2, Ai3), 1 byte out (Ao1) Module = Mod_B 2 bytes in (Bi1, Bi2), 2 bytes out (Bo1, Bo2)

A) Configure Mod_A, Mod_B gives Output map: -

Byte1 Byte2 Byte3

Ao1 Bo1 B02

Operation

Input map:-

Byte1 Byte2 Byte3 Byte4 Byte5

Ai1 Ai2 Ai3 Bi1 Bi2

B) Configure Mod_B, Mod_A gives Output map:-

Byte1 Byte2 Byte3

Bo1 Bo2 Ao1

Input map:-

Byte1 Byte2 Byte3 Byte4 Byte5

Bi1 Bi2 Ai1 Ai2 Ai3

Data is always referred to the Master so output is Control data from Master to Slave and Input data is feedback from Slave to Master. There are many software modules a nd many bytes of da ta. Care must be tak en in correctly selecting and aligning the data into your system.

Modules should have no more than one entry in the configuration list. For reliable operation do not exceed the maximum number of configuration items.

Description

A configuration error will be signalled if the number of modules co nfigured exceeds the maximum number allowed by the Profibus module.

Loss of serial comms may take up to 20 seconds to be signalled. If this occurs the Slave will signal the Master with a ‘Data High’ flag in the Frame Control b yte but will co ntinue to be in Data Exchange w ith the data val ues all set to zero. The extended diagnostics message will be available to the Master.

If RS232 communications are restored the Slave will again signal the Master with a ‘Data High’ flag in the Frame Control byte and will return to ‘good’ Data Exchange values. Again the extended diagnostics message will be available to the Master.

4.6.4 Data exchange values

The Edwards GXS/CXS pump GSD file has been designed to control many different pump types within the GXS and CXS pump family ranges.

Due to the many possible hardware variations some of the GSD file modules will not be applicable or suitable for a particular pump.

Rather than attempting to define the exact pump configuration before data-exchange (a process that would take several minutes) and signal a configuration error for an inappropriate Profibus configur ation select ion, the module will accept any configuration and enter data-exchange very quickly. However at the start of data-exchange this means almost no data will actually be av ailable to the Profibus unit and thus not to the Profibus user. Instead a "CONDITION BYTE" is appended to most of the configurable modules. The condition byte indicates whether the data in that module is both present and valid. The condition byte uses bits as status flags. Flags a re used for 'Valid Object No.' and 'Valid Reading'. A va lid object number indicates the pump has messages for that object number. A valid reading indicates that the object number does not have its ‘No Reading’ flag set. These flags will show condition as invalid (flag bit value of 0) until known to be valid. Thus data exchange will start with the Condition byte status flags set to invalid. The user should ignore all other (preceding) data within that s oftwar e module until both status flag s indicate data is valid.

The condition byte also provides Alarm and Warning bit flags. See below.

Bit No. Function Meaning of 0 Meaning of 1 7 Reserved 6 Reserved 5 Alarm No Alarm Alarm 4 Warning No Warning Warning 3 Reserved 2 Reserved 1 Valid Reading Invalid Valid Reading 0 Valid Object No. Invalid Valid Object

Thus a good condition byte will have the value 03 (hex). Data is not valid (should be ignored) u nless both valid flags are set.

The Warning and Alarm flags may be inhibited i n the pump setup. In this case a Warning or Alarm will not be indicated over Profibus.

The update rate (latency) varies significantly for different parameters, typically between a second and a minute. In addition a pump takes up to 15 seconds from power-up before it starts to communicate with peripherals.

Operation

Byte 2 is condition byte (see Section 4.6.4).

4.7.2 Module 991 - Pump Serial Number

Output Bytes: None Input Bytes: Bytes 1-16 are ASCII characters for Pump serial number Byte 17 is condition byte (see Section 4.6.4).

4.7.3 Module 110 - Remote/Local State

Drypumps have more than one control device that in principle can control the pump. The Drypump will only let one control device have control at a time. This is indicated by this module. At power-up no control device has control. To start a pump, or turn ON any item like a valve, a control device (e.g. Profibus, PDT) must take control. That control device must release control before another control device can turn ON any item. However in some cases a control device can turn OFF an item without having control. The Profibus module only takes control of the pump when it receives a run command from the tool using Module 11 and no other control device has control.

Output Bytes: None Input Bytes: Bytes 1 & 2 form a 16-bit unsigned number which is the object number of the unit which has control of

the pumping system. Example values (decimal): 0=No Control; 61=Drypump Front Panel; 101=PDM1; 102=PDM2; 103=PDT Front; 104=PDT Rear; 110=Profibus in Control; 221=Micro-TIM.

Byte 3 is condition byte (see Section 4.6.4).

4.7.4 Module 992 - Alert Status

This module is a summary of all the warnings and alarms from the pump (except those inhibited by the Drypump internal setting). It does not just sign al alarms and warnings from configured Profibus modules but signals all rece ived alarms and warnings including from functions that cannot be configured through Profibus.

Page 26

D397-53-880 Issue C

Operation

The four input bytes are bit flags. If a flag value is 0 that function has no alert. If the exact cause of a warning is unclear it is recommended the user investigate the pump locally using a PDT.

Output Bytes: None Input Bytes: Byte 1 Bit 7 = Alarm - EMS system Byte 1 Bit 6 = Alarm - Drypump Drive

Byte 1 Bit 5 = Alarm - Mechanical Booster Drive Byte 1 Bit 4 = Alarm - Proximity Booster Drive Byte 1 Bit 3 = Alarm - Drypump Temperature Byte 1 Bit 2 = Alarm - Mechanic al Bo oster Temperature Byte 1 Bit 1 = Alarm - Proximity Booster Temperature Byte 1 Bit 0 = Alarm - Exhaust Temperature Byte 2 Bit 7 = Alarm - Exhaust Pressure Byte 2 Bit 6 = Alarm - Gas Byte 2 Bit 5 = Alarm - Gate Valve Byte 2 Bit 4 = Alarm - Water Flow Byte 2 Bit 3 = Alarm - Service Due Byte 2 Bit 2 = Alarm - System Controller - System Byte 2 Bit 1 = Alarm - System Controller - Device Byte 2 Bit 0 = Alarm - other (any Alarm not in categories above). Byte 3 Bit 7 = Warning - EMS system Byte 3 Bit 6 = Warning - Drypump Drive Byte 3 Bit 5 = Warning - Mechanical Booster Drive Byte 3 Bit 4 = Warning - Proximity Booster Drive Byte 3 Bit 3 = Warning - Drypump Temperature Byte 3 Bit 2 = Warning - Mechanical Booster Temperature Byte 3 Bit 1 = Warning - Proximity Booster Temperature Byte 3 Bit 0 = Warning - Exhaust Temperature Byte 4 Bit 7 = Warning - Exhaust Pressure Byte 4 Bit 6 = Warning - Gas Byte 4 Bit 5 = Warning - Gate Valve Byte 4 Bit 4 = Warning - Water Flow Byte 4 Bit 3 = Warning - Service Due Byte 4 Bit 2 = Warning - System Controller - System Byte 4 Bit 1 = Warning - System Controller - Device Byte 4 Bit 0 = Warning - other (any Warning not in categories above). For example input bytes 00 80 00 E0 would ind icate an Exhaust pressure alarm + Warnings for Exhau st pressure, gas and gate valve.

To start the pump after the pump has stopped due to an alarm, the tool controller must send a Stop command followed by a Start command. See Section 4.7.5.

4.7.5 Module 11 - Pump Control

This is the main control software module. It is used to start and stop ALL connected pump s in sequence. The general start sequence is DP(s) then MB(s) then PB(s). The shutdown sequence is the reverse.

Output Byte: Single byte is Pump Control.

Values: 1=On 2=Fast Shutdown, 3=Auto Shutdown(slow), Other values - ignored.

Note: The value is only sent from the Profibus module to the pump on change of demand state (to prevent rapid

cycling if the pump had an alarm state). Thus if the demand state is on, but the pump has been stopped by something other than the Profibus module, it will be necessary to demand an Off and then an On to restart the pump.
