Ladder Programming Examples
Earlier chapters explained how the configuration word defines the
way a channel operates. This chapter shows the programming
required to enter the configuration word into the processor memory.
It also provides you with segments of ladder logic specific to unique
situations that might apply to your programming requirements. The
example segments include:
• initial programming of the configuration word.
• dynamic programming of the configuration word.
• verifying channel configuration changes.
• interfacing the RTD module to a PID instruction.
• using proportional counts scaling (example).
• monitoring channel status bits.
• invoking autocalibration.
Device Configuration The Application Setup diagram is used for clarification of the ensuing
ladder logic examples and is not intended to represent an RTD
application.
IMPORTANT
Chapter 8 shows a typical application for the RTD module.
