# Chapter 2
Installing and Configuring the DAS

This chapter provides the information you need to install the BASEstar Classic DAS for Modicon programmable controllers and to configure your system.

# 2.1 Installation Requirements

Review the following hardware and software requirements to ensure that your system is prepared for the DAS installation.

Note Back up the disks on your system before installing this software. This will provide a method to restore your system in the event of an installation problem. The procedure for backing up disks is described in the OpenVMS System Management Utilities Reference Manual.

## 2.1.1 Hardware

The DAS for Modicon programmable controllers requires the same hardware as BASEstar Classic device connection management software. For specific information on device connect management hardware requirements, refer to the BASEstar Classic Installation Guide. Additional hardware needed for the DAS for Modicon programmable controllers includes:

If you intend to use the Modbus communication protocol you must have:

- J478 modem for Modicon 584 programmable controllers
- Cables from the host port or LAT port (see the cable wiring diagram in Appendix A)

If you intend to use the Modbus Plus communication protocol you must have:

- SQ85 Network Card (OpenVMS/VAX systems)
- SA85 Network Card (OpenVMS/Alpha systems)
- Modicon 984 series programmable controllers that end in the number 5 (for example 984/385)

If you intend to use Modbus over TCP/IP communications you must have:

- 140 NOE 211 00 (twisted pair) Modicon Quantum Ethernet TCP/IP Module
- 140 NOE 251 00 (fiber optic) Modicon Quantum Ethernet TCP/IP Module

Quantum programmable controllers are configured as Modicon 984 programmable controllers.

## 2.1.2 Software

Before installing the DAS for Modicon programmable controllers, the following software must already be installed:

- OpenVMS Version 5.5-2 or higher (VAX)
- OpenVMS Version 6.1 or higher (Alpha)
- BASEstar Classic for OpenVMS, Version 3.4

For information on installing the above software, refer to the BASEstar Classic Installation Guide.

Note Before using this product on a system, you must first register a License Product Authorization Key (License PAK) using the License Management Facility (LMF). For more information about the License Management Utility, refer to the License Management Utility Manual for OpenVMS.

## 2.1.3 Additional Software

In addition to the above software, if Modbus-Plus is being used the following software must also be installed:

- Modbus-Plus driver for OpenVMS/VAX (SQ85 Network Card)
- Modbus-Plus driver for OpenVMS/Alpha (SA85 Network Card)

In addition to the above software, if Modbus over TCP/IP is being used the following software must also be installed:

- TCP/IP services for OpenVMS

## 2.1.4 Disk Space

Table 2-1 lists the disk space required to install the DAS for Modicon programmable controllers. The space requirements are approximations; actual sizes may vary depending on your system environment and configuration.

Table 2-1 Disk Space Requirements
Peak/Net Usage | Approximate Space Requirements (Blocks)
--- | ---
Peak usage (during installation) | 700 (VAX)
| 1100 (Alpha)
Net usage (after installation) | 550 (VAX)
| 1000 (Alpha)
