■ Intended readers
This manual is intended for system administrators, operators, and programmers. The manual assumes that system administrators will perform system installation, design, and configuration; that operators will perform the day-to-day operations on a configured system; and that programmers will create user programs.
Readers of this manual must have:
-
A basic knowledge of the applicable hardware
-
A basic knowledge of the applicable operating system
-
A basic knowledge of a program for setting up system switchover configurations
-
A basic knowledge of C-language syntax for coding user programs
If you use OpenTP1 or HiRDB to set up your system switchover configuration, we recommend that you first read the relevant OpenTP1 or HiRDB manuals.

In syntax explanations, a vertical bar separates multiple items, and has the meaning of OR. For example: A|B|C means A, or B, or C. |
{ } |
In syntax explanations, curly brackets indicate that only one of the enclosed items is to be selected. For example: {A|B|C} means only one of A, or B, or C. |
[ ] |
In syntax explanations, square brackets indicate that the enclosed item or items are optional. For example: [A] means that you can specify A or nothing. [B|C] means that you can specify B, or C, or nothing. |
... |
In coding, an ellipsis (...) indicates that one or more lines of coding are not shown for purposes of brevity. In syntax explanations, an ellipsis indicates that the immediately preceding item can be repeated as many times as necessary. For example: A, B, B, ... means that, after you specify A, B, you can specify B as many times as necessary. |
■ Conventions: Version numbers
The version numbers of Hitachi program products are usually written as two sets of two digits each, separated by a hyphen. For example:
-
Version 1.00 (or 1.0) is written as 01-00.
-
Version 2.05 is written as 02-05.
-
Version 2.50 (or 2.5) is written as 02-50.
-
Version 12.25 is written as 12-25.
The version number might be shown on the spine of a manual as Ver. 2.00, but the same version number would be written in the program as 02-00.
