1. 0 100 Frequency Maximum Count Value 16 777 215 Appendix A Module Specifications 57 Module Installation Adding Your Module to a Project Appendix B Programming Your Module This chapter explains how program your module in the ControlLogix system It also describes how to the module s input configuration are incorporated into your ladder logic program Topics discussed include e importing the module s configuration profile reviewing accessing and altering configuration options configuring the modules input type and filter settings configuring alarms and limits Incorporating your module into the system is similar to adding any type of I O module You will use your RSLogix 5000 programming software The module is not currently in the pick list of this software so you will use the Generic 1756 Module option as your starting point This feature allows you to inport the configuration database into your project and use ladder logic to set the attributes of each tag These settings control features such as the modules input type channel input range data format filter frequency etc You will need to download the sample project from our website and then import this into your program Then you may access the controller tags to configure the module Ladder logic samples are also provided with this sample project The module has a unique set of tag definitions which are used to configure specific features Chap2. The module communicates with the ControlLogix processor and receives 5 Vdc and 24 Vdc power from the system power supply through the parallel backplane interface You may install as many counter modules in the system as the power supply can support Channels 0 through 7 can receive AC or DC input signals Input types must be configured in channel pairs Each channel reports both count data and rate data in independent registers Extended status information is also available for each channel Chapter 1 Module Overview 3 System Operation At power up the module checks internal circuits memory and basic functions During this time the SYS LED remains on If the module does not find any faults it turns off the SYS LED After completing power up checks the module wait for a connection to an owner controller then valid channel configuration data from your ladder logic program After channel configuration data is transferred and one or more channels are enabled the module continuously converts the inputs to floating point data for use in your ladder program Each time the module reads an input channel the module tests that data for a fault 1 6 signal mismatch or out of range condition If it detects an error condition the module sets a unique bit in the status tags Module Operation The module s input circuitry consists of eight single ended inputs routed into an FPGA The FPGA reads the input signals and converts them to
3. Configuration Changes in an Input Module with Multiple Owners Important Only input modules can have multiple owners If multiple owners are connected to the same input module they must maintain identical configuration for that module In the example below Controller A and Controller B have both been configured to be the owner of the input module When the controllers begin downloading configuration data both try to establish a connection with the input module Whichever controller s data arrives first establishes a connection When the second controller s data arrives the module compares it to its current configuration data the data received and accepted from the first controller If the configuration data sent by the second controller matches the configuration data sent by the first controller the connection is also accepted If any parameter of the second configuration data is different from the first the module rejects the connection and the user is informed by an error in the software The advantage of multiple owners over a Listen only connection is that now either of the controllers can lose the connection to the module and the module will continue to operate and multicast data to the system because of the connection maintained by the other owner controller Note The previous discussion of multiple owners assues the configuration tag configrevnumber is set to 1 Operation differs is the tag is set to 0 R
