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 RTD 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 RTD 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 RTD 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. Table 4.2
contains a list of the registers' 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 power up state which will
reset all 32 registers to their default values.
