2-14 Planning to Use Your ControlNet PLC-5 Processor Understanding Multicast Inputs This feature enables input devices to send the same data to multiple processors simultaneously. Advantages of multicast inputs include: • Network optimization - reduces network usage since data is sent only once simultaneously to all connections. This reduction may allow more complex scheduled connection configurations or improved unscheduled connection performance.
Planning to Use Your ControlNet PLC-5 Processor 2-15 Using Multicast Outputs To use multicast outputs, you must first configure each Multicast Output connection in RSNetworx 3.0: 1. In the Details Tab of Connection Properties dialog, change the Scanner to Target Network Connection to Multicast. You cannot modify this field for any device that does not support multicast outputs. 2. The Scanner to Target Multicast ID of the Details Tab indicates to which multicast output group the connection belongs.
2-16 Planning to Use Your ControlNet PLC-5 Processor Understanding ControlNet I/O Mapping All scheduled data transfers must be mapped on a ControlNet network. You specify where I/O data is to be read from or written to—i.e., mapped. You do this and establish the relationship between processors, I/O adapters, and data-table file addresses by creating and maintaining an I/O map table. An I/O map-table entry is required for each scheduled data transfer.

Planning to Use Your ControlNet PLC-5 Processor 2-19 Discrete I/O Data-Transfer Mapping Regardless of the type of I/O—e.g., 1747, 1771, 1794—all ControlNet discrete I/O data is stored within the processor according to the corresponding I/O map-table entry. Discrete I/O data can be stored in either the I/O image table or the DIF/DOF. Any status information transferred along with the I/O data is stored in a separate status file that you specify during configuration.
2-20 Planning to Use Your ControlNet PLC-5 Processor 1771 Modules ControlNet 1771 discrete I/O data-transfer mapping requires one map-table entry per node. ControlNet 1771 non-discrete I/O data-transfer mapping requires one map-table entry per module. The ControlNet scheduled I/O data-transfer mechanism makes it possible to eliminate block-transfer programming to communicate with the 1771 modules. For a complete list of these modules, refer to RSNetWorx for ControlNet documentation.
Planning to Use Your ControlNet PLC-5 Processor 2-21 Other ControlNet Processors ControlNet scheduled peer-to-peer communications between ControlNet processors require one map-table entry per message. You can set up ControlNet peer-to-peer communications between any two processors on a ControlNet network. The ControlNet transfer mechanism makes it possible to map the scheduled peer-to-peer messages listed in the following table. Table 2.

4-6 1771 ControlNet Transfers in PIIs and STIs When a 1771 Read or 1771 Write CIO instruction is encountered in a PII or STI, the processor resumes execution of lower priority ladder programs (main logic programs) until the CIO is completed. If you want the PII or STI to run to completion before returning to your main logic program, place the CIO instruction inside of a UID/UIE pair in your PII or STI program file.
4-7 In the previous example, an IDI is initiated that updates the destination file from the private buffer before the next normal input-image update. The Data File Offset (232) is the offset into the buffer where the data is stored. The Length (10) identifies the number of words in the transfer—it can be an immediate value ranging from 1 to 64 or a logical address that specifies the number of words to be transferred. The Destination (N11:232) is the destination of the words to be transferred.
4-8 An IDO is initiated that updates the private memory output buffer from the source file before the next normal output-image update. The Data File Offset (175) is the offset into the buffer where the data is stored. The Length (24) identifies the number of words in the transfer or a logical address that specifies the number of words to be transferred. The Source (N12:175) is the source of the words to be transferred.
4-9 Using Selectable Timed Interrupts with a Program on a ControlNet Network You must be careful when using Selectable Timed Interrupts (STIs) with a program on a ControlNet network. A Selectable Timed Interrupt (STI) periodically interrupts primary program execution in order to run a subprogram to completion.
