This chapter provides the information you need to install the
DAS for Siemens H1 Protocol and to configure your system.
2.1 Installation Requirements
The DAS for Siemens H1 Protocol can be installed by a system manager who has access to an account with the SYSPRV privilege. However, modifications to the hardware configuration of the host must be done by trained Digital service personnel.
The installation takes 1 to 5 minutes depending on distribution media and system configuration, and is carried out using the standard OpenVMS utility VMSINSTAL. You only need to respond to simple YES or NO questions during the installation.
Review the following hardware and software requirements to ensure that your system is prepared for the DAS installation.
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. |
The DAS for Siemens H1 Protocol communicates with Siemens programmable controllers using the H1 protocol over Ethernet. The DAS for Siemens H1 Protocol requires the same hardware as BASEstar Classic device connection management. For more information on hardware requirements, see the BASEstar Classic Installation Guide. The same Ethernet controller may be shared between DECnet Plus and the DAS for Siemens H1 Protocol.
Siemens model S135 programmable controllers are multiprocessor programmable controllers. They allow multiple CPUs to coexist in the same programmable controller. There is one MUX/Coordinator card which coordinates data traffic between the CPUs and to the Ethernet communication card. When performing control operations such as upload or download, it is necessary to connect a special RS-232 cable between the Ethernet communications card and the CPUs or between the Ethernet communications card and the Coordinator.
If the RS-232 cable is connected to the Coordinator card, then control operations may be performed to any one of the CPUs.
It is recommended that the DIP switch on the Coordinator card is set so that the leftmost CPU is addressed as CPU number 1. Also, the toggle switch of the Coordinator should be set to RUN or TEST mode. |
If the RS-232 cable is connected directly to the CPU card, then all
control operations are restricted to that CPU only.
2.1.2 Software Requirements
Before installing the DAS for Siemens H1 Protocol, the following software must already be installed:
For information on installing the above software, see the BASEstar Classic Installation Guide and DECnet Plus for OpenVMS Installation and Configuration.
The minimum required version of DECnet Plus is different for the various versions of OpenVMS. Refer to DECnet Plus for OpenVMS Installation and Configuration for the minimum required version of OpenVMS required for the version of DECnet Plus being installed.
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. |
Table 2-1 lists the disk space required to install the DAS for Siemens H1 Protocol. The space requirements are approximations; actual sizes may vary depending on your system environment, configuration, and software options selected.
| Peak/Net Usage | Approximate Space Requirements |
|---|---|
| Peak usage (during installation) | 500 blocks (VAX) |
| 600 blocks (Alpha) | |
| Net usage (after installation) | 300 blocks (VAX) |
| 400 blocks (Alpha) |
