Chapter 2 Planning to Use Your ControlNet PLC 5 Processor Unscheduled Data Transfer Operations on a ControlNet Network The ControlNet network allows you to use unscheduled messaging when deterministic delivery is not required.
Chapter 2 Planning to Use Your ControlNet PLC 5 Processor Table 2.B ControlNet Unscheduled Data Transfer Operations Operation Description Features Non discrete Perform ladder initiated unscheduled non discrete I/O data transfers on a ControlNet network by using ControlNet I/O Transfer (CIO) instructions.
Chapter 2 Planning to Use Your ControlNet PLC 5 Processor Operation ① Description Features Because connections are opened and closed as needed, more can exist in a program as long as no more than this number are active at one time. Using I/O Forcing Operations ControlNet I/O forcing occurs in the same way as remote I/O forcing in the PLC-5/20 and -5/40 processors. The processor performs the forcing and transmits the forced data to the output- and input-image tables.

Chapter 2 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.
Chapter 2 Planning to Use Your ControlNet PLC 5 Processor Remote I/O The following table shows the default number of input and output words reserved by the 6200 PLC-5 Programming Software for the different sizes and addressing modes of non-ControlNet remote I/O if you first configure non-ControlNet remote I/O on your processor: Addressing Mode 2 Slot 1 Slot 1/2 Slot 4 Slots 2 4 8 Number of Words Reserved 8 Slots 12 Slots 16 Slots 4 6 8 8 12 16 16 24 32 The 6200 PLC-5 Programming Software reserves non-C
Chapter 2 Planning to Use Your ControlNet PLC 5 Processor Mapping ControlNet Data Transfer The ControlNet I/O map table can contain up to 64 entries. Each maptable entry corresponds to one transfer—either input or output—of data between the ControlNet processor and an I/O rack, an I/O module, or another ControlNet processor. Table 2.
Chapter 2 Planning to Use Your ControlNet PLC 5 Processor Map Table Entry Field Description Input File and Size This is the offset in the input file where the data is to be stored and the number of words to be received from the input device. For discrete I/O data transfer, the offset is into the input image table; for non discrete I/O data transfer or peer to peer communication with another ControlNet processor, the offset is into the Data Input File entered on the ControlNet configuration screen.

Chapter 2 Planning to Use Your ControlNet PLC 5 Processor The types of modules that may be accommodated by the processor’s scheduled non-discrete I/O data-transfer mechanism are typically those modules that require a one-time configuration and then continuously read or write. To communicate with the modules listed in Table 2.G as well as with other 1771 analog modules, you can also include explicit CIO instructions in your ladder-logic program. See pages 4-4 and C-1 for more information.
Chapter 2 Planning to Use Your ControlNet PLC 5 Processor To communicate between any ControlNet PLC-5 processors on the ControlNet network, you can include explicit MSG instructions in your ladder-logic program.

Appendix C ControlNet Instruction Set Immediate Data I/O Instructions Instruction Description IDI IMMEDIATE DATA INPUT Data file offset Length 232 If the input conditions are true, an immediate data input is initiated that updates the destination file from the private buffers before the next normal input image update. The Data file offset (232) is where the data is stored.
Appendix D ControlNet I/O Map Entry Status Words and Error Messages I/O Map Entry Status Words The ControlNet status file is an integer data-table file that you specify and configure with the I/O map for scheduled-I/O usage. It containing status information about all of the ControlNet network’s scheduled I/O connections. Each I/O map-table entry has a status-file offset field pointing to three status words associated with the connection.
Appendix D ControlNet I/O Map Entry Status Words and Error Messages Error Messages The following is a list of ControlNet error codes, messages, possible causes, and possible corrective actions: Decimal Code Hex.
Appendix D ControlNet I/O Map Entry Status Words and Error Messages Decimal Code Hex.
