4 INSTALLATION

The generation and installation of the motei module follows VLT standards as described in [2].

4.1 General Requirements

The motei module requires the availability of Hardware and Software detailed in [2], CCS or CCS-lite and the following modules as of VLT Common Software Release OCT98:

· seq version 2.25 or higher

· panel version 4.12 or higher

· uif version 3.9 or higher

· samp version 1.48 or higher

· mcm version 2.7 or higher

4.2 Database configuration

In both LCU & WS environments (not on CCS-lite), the database shall contain MCM motor branches. As described in [2], chapter 4, section 4, a motor branch is instanciated from the base class motMOTOR, or from any specialized sub-class, such as motDVA0X, motDVAMA, motDVAMI, motDXXMA, motDXXMI & motSVSMS, derived from the main class motMOTOR, by overloading.

Dedicated to the Engineering Interface, 6 motors have been instanciated resp. from each sub-class. These branches are collected in the file moteiDATABASE.db(5) (see 5.3.1) that may be included in the environment configuration file $VLTDATA/ENVIRONMENTS/<mcmEnv>/dbl/DATABASE.db.

On WS/CCS environment, the motor branches are located under :Appl_data:MOTEI

On LCU environment under :MOTEI

The motors are aliased according to their class names : DVA0X, DVAMA, DVAMI, DXXMA, DXXMI & SVSMS.

The tables default to the maximum number of entries and preset the HW initialization sequence to one single action END, implying that the motor may be initialized without motion therefore enabling the normal motions for tuning.

The following table describes the 6 motors as of their HW configuration, all axis are linear, the board parameters are preset to their default values:

MOTOR	Motor	Encoder	Servo Amplifier	Motion Controller
DVAMI	DC	Incremental	VME4SA	MAC4-INC
DVAMA	DC	Absolute	VME4SA	MAC4-SSI
DVA0X	DC	none	VME4SA	none
DXXMI	DC	Incremental	stand-alone	MAC4-INC
DXXMA	DC	Absolute	stand-alone	MAC4-SSI
SVSMS	Stepper	Incremental	stand-alone1	MAC4-STP

1 VME4ST or compatible

Below is an example of the file $VLTDATA/ENVIRONMENTS/<mcmEnv>/dbl/DATABASE.db :

The database will contain the 6 template motors instanciated in moteiDATABASE.db and one motor aliased MI.

4.3 LCU Configuration

It is recommended to use the tool vccConfigLcu(1) to set-up the modules and processes required in the LCU-side of MCM:

1. System Modules:

a. lcudrv, lculog, lqs

b. drivers: ampl, mcon

c. optional drivers : acro (for signals), tim

d. lcc, cai

e. scan (optional)

2. User Modules:

a. mcm

b. ntp (optional)

3. Processes:

a. lccServer, msgServer, rdbServer

b. motServer

See [3] or the corresponding man-pages for instructions to use the vccConfigLcu tool.

The figure shown below is an example of a LCU configuration for the MCM Engineering Interface:
