Page 11: Produce And Consume A Tag
Chapter 1 Produce and Consume a Tag A Logix 5000™ controller lets you produce (broadcast) and consume Introduction (receive) system-shared tags. Term Definition Produced tag A tag that a controller makes available for use by other controllers. Multiple controllers can simultaneously consume (receive) the data. A produced tag sends its data to one or more consumed tags (consumers) without using logic. -

Page 23: Rpi Limitations And Negotiated Default
Produce and Consume a Tag Chapter 1 Example: Reconstruct a floating point value. The two MOV instructions reverse the order of the integers as the integers move to a new location. Because the destination of the COP instruction is a floating-point address, it takes two consecutive integers, for a total of 32 bits, and converts them to a single floating- point value. - Page 24 Chapter 1 Produce and Consume a Tag Tip: The controller’s backplane and Ethernet ports can support different RPIs. If multiple consumers need to connect to the controller at different RPIs, you can configure them to connect through the backplane or the Ethernet port. Connection requirements of a produced or consumed tag page 12 more information.

Page 25: Set Rpi Limits, Default For Producer Tag
Produce and Consume a Tag Chapter 1 Important: RPI limits and default values are not supported for safety tags and AXIS tags. AXIS produced tags are produced at a rate equal to the Coarse Update Period of the associated motion group. Safety produced tags are produced at a rate specified by the Safety Task Period. - Page 26 Chapter 1 Produce and Consume a Tag 2.

Produce and Consume a Tag Chapter 1 Unicast connections are point-to-point connections between a producing Unicast connection controller and consuming controller; no multiple connections. Unicast option connections do not require a minimum or maximum RPI range or default RPI value. The Allow Unicast Consumer Connections check box at the bottom of the Advanced Options dialog box is selected by default to allow multiple unicast consumers to consume from the produced tag. - Page 28 Chapter 1 Produce and Consume a Tag The Consuming controller must be set up to allow its consumed tags to Set up the accept an RPI provided by the producer.

Page 32: Produced And Consumed Rpi Scenarios
Chapter 1 Produce and Consume a Tag The following scenarios explain how producing and consuming tags Produced and exchange RPI for controllers. consumed RPI scenarios The RPI is within range of the producing controller’s RPI Limits. Scenario 1 There is no default RPI that is set up for the producing controller. Version 17 and earlier: The consuming controller is brought online with an RPI configured at 3 ms. -
Page 33: Scenario 2
Produce and Consume a Tag Chapter 1 The RPI is outside the range of the producing controller’s RPI Limits. Scenario 2 There is no default RPI that is set up for the producing controller. Version 17 and earlier: The RPI requested by the consumed tag is not within the range of the producer. -
Page 34: Scenario 3
Chapter 1 Produce and Consume a Tag The RPI is outside the range of the producing controller’s RPI Limits. A Scenario 3 default RPI is set up for the producing controller. But, the network path contains a bridge that blocks the negotiated RPI to prevent an interruption to other controllers on the network. -
Page 35: Scenario 4
Produce and Consume a Tag Chapter 1 The RPI is outside the range of the producing controller’s RPI Limits. A Scenario 4 default RPI is set up for the producing controller. The consumer is set up to accept the RPI provided by the producer. Version 17 and earlier: The RPI requested by the consumed tag is not within the range of the producer. - Page 36 Chapter 1 Produce and Consume a Tag Similar to other controllers, the 1769-L2x and 1769-L3x controllers will verify that the RPI of incoming connections are within the produced tag settings. If the consuming tag’s RPI falls outside the configured range, a producing controller will reject the incoming RPI and then provide an RPI (default) to the consuming controller.

Page 39: Introduction
Chapter 2 Produce a Large Array The Logix5000 controller can send as many as 500 bytes of data over a Introduction single scheduled connection. This corresponds to 125 DINT or REAL elements of an array. To transfer an array of more than 125 DINTs or REALs, use a produced/consumed tag of 125 elements to create a packet of data. -
Page 40: Produce A Large Array
Chapter 2 Produce a Large Array In addition, the array must contain an extra 122 elements. In other words, it must be 122 elements greater than the greatest number of elements that you want to transfer. • These elements serve as a buffer. •... - Page 41 Produce a Large Array Chapter 2 6. Enter this logic. When the offset value in array_ack[0] is not equal to the current offset value but array_ack[1] equals -999, the consumer has begun to receive a new packet, so the rung moves -999 into the last element of the packet. The consumer waits until it receives the value -999 before it copies the packet to the array.
- Page 42 Chapter 2 Produce a Large Array When the offset value in array_ack[0] is equal to the current offset value, the consumer has copied the packet to the array; so the rung checks for more data to transfer. If the offset value plus 123 is less than the size of the array, there is more data to transfer;...
- Page 43 Produce a Large Array Chapter 2 7. In the Controller Tags folder of the controller project that consumes the array, create these tags. Tag Name Type array_ack DINT[2] array_packet DINT[125] 8. Convert array_packet to a consumed tag. Specify Controller Name of the controller that is sending the packet.
- Page 44 Chapter 2 Produce a Large Array When the offset value in array_packet[123] is different than the offset value in array_ack[0], the controller has begun to receive a new packet of data; so the rung checks for the value of -999 in the last element of the packet. If the last element of the packet equals -999, the controller has received an entire packet of new data and begins the copy operation.
- Page 45 Produce a Large Array Chapter 2 • Messages are unscheduled and are executed only during the ‘system overhead’ portion of the Logix5550 execution. Therefore, messages can take a fairly long time to complete the data transfer. • You can improve the transfer time by increasing the system overhead time slice, but this diminishes the performance of the continuous task.
