4.0 PROGRAMMING
This section describes how the data is organized in the module and
provides examples of how the module is accessed by application
programs.
For DCS 5000 and AutoMax version 2.1 and earlier, you must assign
variable names to registers by writing a configuration task. For
AutoMax version 3.0 and later, you define registers using the
ReSourcet AutoMax Programming Executive. After these variables
are defined, you can generate the configuration file automatically,
which eliminates the requirement to write a configuration task for the
rack. If you are using AutoMax version 2.1 or earlier, refer to
Appendix F for a sample voltage input configuration task. If you are
using AutoMax version 3.0 or later, refer to the AutoMax
Programming Executive Instruction Manual (JĆ3750) for more
information. Note that AutoMate systems require no special
configuration procedure to use the Voltage Input module.
For additional programming information refer to the AutoMate 30/40
Software Instruction Manual (JĆ3150), the DCS 5000/AutoMax
Configuration Task Instruction Manual (JĆ3649), or the AutoMax
Programming Executive Manual (JĆ3750).
4.1 Register Organization
The Voltage Input module uses 32 registers to store and organize its
data. The same registers are used whether the module is in a local
rack or a remote rack. See Table 4.1 for a list of the registers. Note
that writing to a readĆonly" register will result in an I/O error. Table
4.2 contains a list of register default values. When the module is used
in a DCS 5000/AutoMax system and a Stop All command is received,
the module will be placed in a powerĆup state, which will reset all 32
registers to their default values.
