It lists the types and variations of reflex blocks that can be created using the Advantys configuration software and explains how two blocks may be combined in a nested reflex action What's in this This chapter contains the following topics Chapter? Topic P What Is a reflex Action 10 An Overview of Reflex Action Types 15 Configuring a Reflex Block 24 The Virtual module 28 The Action module How Action Modules Respond to Fallback Conditions 34 Nesting Two Reflex Blocks 36 Reflex Action Start-up States 890USE18300 September 2003 Introduction What s a reflex action Summary Reflex actions are small routines that perform dedicated logical functions directly on the Advantys island bus. They allow output modules on the island to act on data and drive field actuators directly, without requiring the intervention of the fieldbus master a typical reflex action comprises one or two function blocks that perform Boolean AND or exclusive-OR operations comparisons of an analog input value to user-specitied threshold values up-or down-counter operations timer operations the triggering of a latch to hold a digital value high or low o the triggering of a latch to hold an analog value at a specific value The island bus optimizes reflex response time by assigning the highest transmission priority to its reflex actions. Reflex actions take some of the processing workload off the fieldbus master, and they offer a faster, more efficient use of system bandwidth How reflex Reflex actions are designed to control outputs independently of the fieldbus master Actions Behave controller. They may continue to turn outputs on and off even when power is removed from the fieldbus master. Use prudent design practices when you use reflex actions in your application WARNING UNEXPECTED OUTPUT OPERATION △ For outputs that are configured to respond to reflex actions, the output state represented in the island's network interface module(niM) may not represent the actual states of the outputs Turn off field power before you service any equipment connected to the island e For digital outputs, view the echo register for the module in the process image to see the actual output state e For analog outputs, there is no echo register in the process image To view an actual analog output value, connect the analog output channel to an analog input channel Failure to follow this precaution can result in death, serious injury, or equipment damage. 10 890USE18300 September 2003
