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

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

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

The Drypump Profibus Module p rovides a Profibus DP V0 slave interface for Edwards drypumps with a PDT (Pump Display Terminal) port. This does not include older pumps with a PDM (Pump Display Module) port. 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. Most drypumps provide the DC power for the module. The front panel of the module has four L EDs which indicate the status of the module and the Profibus network. he Profibus slave address is set using ro tary switches. The ba ck 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 drypump and a power connector.

WARNING

Installation

3.3 Electrical connections

Figure 6 - DIN rail mounting the module

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 Drypump when the pump or tool are "On Process". The Profibus module uses a Drypump's PDT port (normally a 5-way XLR socket) for communication with the Drypump.

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.

Some PDT connectors are not able to supply enough power to operate the Profibus modu le . However for mos t pump types an alternative power source will be available. See Table 4 below.

D397-52-880 Issue D

3.3.1 Connection to a PDT Port only

If connecting to a PDT port capable of powering the Profibus module then either use the cable provided in the kit (5m long) or cable length may be increased using 5-way XLR extension cables. See Section 7.2.

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 Drypump PDT port.

3.3.2 Connection to a PDT Port and a LON Port

Where connections to both a PDT socket and a LON socket is required the LON/PDT power/RS-232 splitter cable mu st be used. See Section 7.2. This is to be used with the cable provided in this kit. The 5-way XLR plug of the long cable should be connected to the 5-way XLR socket of the short splitter cable to make one cable assemb ly. The XLR plugs can then be connected to the pump and the 9-way D-type and power connector connected to the Profibus module. Cable length may be increased using 5-way XLR extension cables. See Section 7.2.

Figure 7 - Profibus module rear connections

Installation

3.4 Profibus network connection

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

Operation

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 "EDW0BC2.GSD", which is registered with the Profibus association. When configuring your system the "ID" number will be 0BC2 and the unit's description will be “Edwards Drypump”.

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).

Note: If the address is set to a value greater than 125 (decimal) or 0, the RED error LED will flash at 1 Hz and the

module will go online. If this occurs either, change the address and cycle the power or remove power and change the address.

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.

D397-52-880 Issue D

Operation

4.6.1 Parameterisation

Only the Profibus mandatory 7 bytes of parameterisat ion data are used by the Dryp ump 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

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 outp ut is control data from Mas ter to Slave a nd input da ta is feed ba ck 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 byte but will continue to be in data exchange with the data values 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.

Operation

4.6.4 Data exchange values

The Edwards Drypump GSD file has been designed to control all types of Edwards Drypumps with a PDT port. This includes:

 Many different pump families (for example iH, iGX, iXH).  Different pump types (standard Drypumps, mechanical boosters and proximity boosters).  Variations of which accessories are fitted (for example gas modules, exhaust and water sensors).

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 available 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 st atus flags. Flags are use d for 'Valid Object No.' and 'Valid Reading'. A valid 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 software module until both status flags 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

D397-52-880 Issue D

Operation

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 in the Drypump setup. In this case a Warning or Alarm will not be indicated over Profib us.

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

Operation

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 and 2 form a 16-bit unsigne d 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.

The four input bytes are bit flags. If a flag value is 0 that function has no alert. If the exact caus e 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 - Mechanical booster 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 indicate an exhaust pressure alarm + warn ings for exhaust

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 shut down sequence is the reverse.
