1.1 Scope

This manual provides Operation instructions for serial interface communications to the Edwards Turbo Instrument Controller product range, part numbers:

Description Item Number TIC Instrument Controller D397-00-000

TIC Instrument Controller 6-Gauge D397-01-000 TIC Instrument Controller 6-Gauge Capacitance Manometer D397-02-000 TIC Turbo Controller 100 W D397-11-000 TIC Turbo Controller 200 W D397-12-000 TIC Turbo & Instrument Controller 100 W D397-21-000 TIC Turbo & Instrument Controller 200 W D397-22-000

Before using these instructions, ensure that you have a good understanding about the operation of the controller.

Introduction

1.2 Message basics

The communications to the TIC work on a master/slave principle. The TIC is the slave and will only transmit a message in response to one sent to it. The master, a PC for example, must always start the conversation.

A conversation consists of a message to the TIC and its response b ack. Having sent a message to the TIC, wait for the reply before continuing.

There are two basic types of message sent to the TIC:

 Command sending information to the TIC (!).  Query requesting information from the TIC (?).

All messages end with a carriage return. In multi-drop mode, the ? and ! are preceded by the addressing information. Characters not enclosed by start (!?) and end (cr) characters will be ignored. Incomplete messages will be ignored if

a new start character is received.

1.2.1 Commands

Commands send information to the TIC. These can be literal commands such as 'turn pump on' or setups to be stored by the TIC. Setups hold information about how the TIC should behave such as the conditions under which the vent valve should open.

1.2.2 Queries

Queries request information from the TIC. These can be direct queries of the value of a parameter such as pump speed, or reading the setup value currently in the TIC.

D397-30-880 Issue H

Introduction

1.2.3 Responses

Responses from the TIC contain either the data requested (=) or the status of the command (*). Note that for commands such as Upload/Download, the action will continue after the response has been received. Also detailed checking is performed by the objects themselves so a good response only guara ntees that the message was accepted by the serial communications, correct behaviour must be checked by querying the appropriate attribute. For example write a setup, read it back and check the updates are as requ ested.

1.2.4 Setup

Some objects have more than one setup, for these objects the config type is sent and returned as the first paramete r in the data field.

1.3 DX, nEXT and nXDS pumps

The TIC will pass messages to the DX, nEXT or nXDS pump and return the replies. It limits some of the commands that can be sent directly as the TIC must take account of setups and inputs connected to it. For example, if SYSI is set into the fail condition; the turbo pump must not run so on/off commands directly to the DX, nEXT or nXDS are always ignored, use the TIC turbo object instead.

Under a fault condition the DX and nEXT move through their state machines slightly differently. The TIC adjusts the information from the nEXT so the TIC’s states move like the DX for both pum p types. On fault the TIC shows both pumps as fault braking until a stop command is issued. At this point the fault is cleared from the pump object 904 and the front panel.

When not using the TIC the main visible difference is that the DX clears its fault bits and fault LED when a stop command is issued. The nEXT does not clear them until both a stop and then a start command are issued.

1.4 Communications timings

Because of the complexity of the product precise message timings are not defined, however, the following are provided for guidance:

 Basic messages less than 100 mSecs  Messages to DX, nEXT or nXDS (dependent on DX or nEXT behaviour) less than 200 mSecs  Suggested timeout in master 500 mSecs  Upload Turbo (DX/nEXT) less than 2 secs  Download Turbo (DX/nEXT) less than 4 secs

1.5 Object IDs

This sub-section summarises the protocol, based on the use of object IDs, to identify sources and destinations in messages.

Objects can be physical items such as gauges and pumps, or virtual items such as software modules and data records. Each object is allocated a unique identification number, although two instances of a particular item will both have the same ID. In a message, the Object ID consists of 1 - 5 ASCII digits representing a number between 1 - 65535, as shown below:

Data fields contain command codes, parameter values or response codes, and will vary in length and format according to the message type. If there is more than one item in the data field, each item is separated by a semi colon(;).

D397-30-880 Issue H

A returned response code consists of 1 or 2 characters representing a number between 0_99. A code of '0' always means 'OK'. Other codes can be used to indicate various error conditions:

Where several items are linked together using multiple RS232 lines radiating from a hub, a 'multi-drop' identifier is prefixed to each message. It is composed of a '#', followed by a 2 character Destination ID, a colon, and a 2 character Source ID:

This covers operations specific to the PC serial link covering control, monit orin g a n d se tup of all sections of the TIC and the attached pumps.

Objects in the DX, nEXT or nXDS pump can be read via the TIC at their normal object ID and the TIC will pass the messages on and return the reply, refer to DX, nEXT or nXDS requirements Section 1.3. Wait for the reply before sending in another message even if the new message is for the TIC or 'other' pump.
