Chapter 2
Installing and Configuring the DAS

This chapter provides the information you need to install the 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 for Modicon programmable controllers installation.

2.1.1 Hardware

The hardware requirements for the DAS for Modicon programmable controllers are the same as those for the BASEstar Open software. For specific hardware requirements, refer to the BASEstar Open for OpenVMS Installation Guide .

Additional hardware required for configuring the DAS for Modicon programmable controllers using Modbus includes:

Figure 2-1 shows the required hardware for each model of programmable controller.

Figure 2-1 Modbus Communications


The cable to the J478 Modbus modem must be terminated with a 25 pin male RS232-C connector with pinouts as shown in Figure 2-2.

Figure 2-2 Modbus RS-232 Pinouts


Additional hardware required for configuring the DAS for Modicon programmable controllers using Modbus Plus includes:

The SQ85 or Q984 card fits only into a VAX Q-BUS backplane.

The SA85 card fits only into an Alpha ISA backplane.

Figure 2-3 shows the hardware required to use Modbus Plus.

2.1.2 Software

The following software must be installed prior to installing DAS for Modicon programmable controllers:

For more information on installing BASEstar Open software, refer to the BASEstar Open for OpenVMS 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:

The Modbus Plus driver for OpenVMS/VAX is obtained from Schneider Automation, Inc. The Modbus Plus driver for OpenVMS/Alpha is obtained from IPACT (Integrated Process Automation and Control Technologies).

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

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
Usage Approximate Space Requirements (Blocks)
Peak (during installation) 950 (Alpha)
  3000 (VAX)
Net (after installation) 450 (Alpha)
  1500 (VAX)
