Chapter 1 What is the 1756-SYNCH module? This chapter describes the ControlLogix SynchLink module. It also describes what you must know and do before using the SynchLink module. Table 1.
1-2 What is the 1756-SYNCH module? Why Synchronize Time Between Chassis? In synchronizing time between chassis, the SynchLink module allows you to: • share motion data from chassis to chassis because a consistent time reference is available among chassis for interpolation of velocity and position data. • timestamp I/O in multiple chassis and have a common time reference with which to compare the timestamps.
What is the 1756-SYNCH module? Connecting a SynchLink Module to a SynchLink System 1-3 ControlLogix SynchLink modules mount in a ControlLogix chassis and connects to other SynchLink node through a fiber optic cable system. For more information on the available fiber optic cables, see Table 1.2. Table 1.2 Fiber Optic Cables Available with the 1756-SYNCH Module Catalog number: Cable length 1403-CF001 1m (3.28ft) 1403-CF003 3m (9.84ft) 1403-CF005 5m (16.4ft) 1403-CF010 10m (32.

Physical Features of the ControlLogix SynchLink Module Figure 1.1 Module side view Module front view LINK COMM LINK SYNC OK Backplane Connector- Interface to the ControlLogix system backplane Status Indicators 42744 Transmit Fiber Port Receive Fiber Port Table 1.4 lists descriptions of the physical features shown in Figure 1.1. Table 1.
What is the 1756-SYNCH module? Using Module Identification and Status Information 1-5 Each ControlLogix SynchLink module maintains specific identification information that separates it from all other modules. This information assists you in tracking all the components of your system. For example, you can track module identification information to be aware of exactly what modules are located in any ControlLogix rack at any time. While retrieving module identity, you can also retrieve the module’s status.
1-6 What is the 1756-SYNCH module? Preventing Electrostatic Discharge This module is sensitive to electrostatic discharge. ATTENTION This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment: • Touch a grounded object to discharge potential static. • Wear an approved grounding wriststrap. • Do not touch connectors or pins on component boards.
Chapter 2 Time Synchronization in the ControlLogix System This chapter describes how the ControlLogix SynchLink module fits in the ControlLogix system. Table 2.
2-2 Time Synchronization in the ControlLogix System Using the Coordinated System Time (CST) The Coordinated System Time (CST) is the clocking mechanism used to achieve time synchronization in a ControlLogix chassis. The ControlLogix Coordinated System Time (CST) clock is a 64-bit clock on the backplane of the ControlLogix chassis. It has a 1μS resolution and is used as the main time reference for all modules plugged into a chassis backplane.
Time Synchronization in the ControlLogix System 2-3 Multiple Rockwell Automation products can be synchronized with SynchLink. In addition to the SynchLink module, the PowerFlex 700S and the 1756-DMxxx series products (both used for drive control) also use SynchLink to achieve drive to drive synchronization.
2-4 Time Synchronization in the ControlLogix System System Synchronization When a SynchLink system is initialized, the individual SynchLink nodes power-up at separate times and the individual SynchLink node clocks begin to count at arbitrary points in time. When this occurs, the system is not yet synchronized. As the master node clock counts, it reaches a point where it rolls over and goes back to zero.
Time Synchronization in the ControlLogix System How Do the CST Clock and SynchLink Node Clock Work Together? 2-5 As stated earlier, the ControlLogix Coordinated System Time clock (CST) is a 64-bit clock on the ControlLogix backplane. It is used as the main time reference for all modules plugged into a ControlLogix chassis. The SynchLink node clock is used to establish the time reference on the SynchLink fiber. Figure 2.
2-6 Time Synchronization in the ControlLogix System SynchLink communications are a unidirectional data transfer from one SynchLink node to another. Each configuration starts with a single Master Node. The SynchLink network can be configured in the following ways. What are the SynchLink Configurations? • Star Configuration • Daisy Chain Configuration • Ring Configuration Do not mix the configurations (i.e. begin in the star configuration and change to the daisy chain configuration).
Time Synchronization in the ControlLogix System 2-7 Daisy Chain Configuration In the daisy chain configuration, the SynchLink network starts at the Master Node and ends at an End Node. You can include Center Nodes (shown in Figure ) in the configuration as needed. Figure 2.6 Master Node SynchLink Center Node Center Node End Node ControlNet 42746 IMPORTANT In the daisy chain configuration, you can use a maximum of 10 nodes, including the master and end nodes.
2-8 Time Synchronization in the ControlLogix System Ring Configuration The ring configuration is a permutation of the daisy chain configuration. In the ring chain configuration, the SynchLink network starts and ends at the Master Node. You can include Center Nodes (shown in Figure ) in the configuration as needed. Master Node SynchLink Center Node Center Node Center Node ControlNet 42748 IMPORTANT In the ring chain configuration, you can use a maximum of 10 nodes.
Chapter 3 SynchLink Module Features This chapter describes the ControlLogix SynchLink module features. Table 3.
3-2 SynchLink Module Features Module Features That Cannot Be Configured These general module features (e.g. Removal and Insertion Under Power) are supported on the module regardless of configuration and application.
SynchLink Module Features 3-3 Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation. Module Fault Reporting ControlLogix SynchLink modules provide both hardware and software indication when a module fault has occurred. Each module’s LED fault indicator and RSLogix 5000 will graphically display this fault and include a fault message describing the nature of the fault.
3-4 SynchLink Module Features Status Indicator (LED) Information The ControlLogix SynchLink module has status indicators (LED) on the front of the module that allow you to check the module health and operational status. With the LED indicators, you can check: • SynchLink and ControlLogix backplane status • Module health status For examples of LED indicators, see page 6-1.
SynchLink Module Features 3-5 Use Last Configuration When Connection to Owner-Controller Closes - For Module’s Using Firmware Revision 2.18 or Greater With firmware revision 2.18 or greater, the 1756-SYNCH module can continue to operate, using its last configuration, when the module’s connection to the owner-controller closes. Table 3.2 If the 1756-SYNCH module is used in this scenario: • The 1756-SYNCH module is located in a chassis with two ControlLogix controllers.
3-6 SynchLink Module Features transferred between them). The SynchLink module can receive and transmit data and, therefore, uses a Receive Port Communications Format and Transmit Port Communications Format. SynchLink messages are structured as six 32-bit words; the words are divided into three types as described in Table 3.3: Table 3.3 Word Type: Description: Direct Data delivered in a single message. A SynchLink message can contain a maximum of four direct data words; each word is 32 bits in length.
SynchLink Module Features 3-7 Multiple Port Communications Formats in Single Module You must set a communications format for receiving data (Receive Port Communications Format) and transmitting data (Transmit Port Communications Format) in each SynchLink module. The following requirements apply to communication format choices: • If a SynchLink module does not receive data (e.g.
3-8 SynchLink Module Features Module-Defined Data Tags When you create a module, RSLogix 5000 creates module-defined data types and tags. These tags allow you to access the Configuration, Input and Output Data of the module via the controller’s ladder logic. The types of tags created vary, depending on which communications format you choose when creating a module.
SynchLink Module Features 3-9 The SynchLink module updates its receive and transmit buffers once every 500μS. Because direct data can be passed through from node to node once every 50μS, up to 10 nodes can be updated with direct data in a single 500μS SynchLink scan. Pass-through functionality only applies to direct data in a daisy chain configuration, though; axis data and buffered data cannot be passed through.
3-10 SynchLink Module Features Table 3.
SynchLink Module Features 3-11 Electronic Keying Instead of plastic mechanical backplane keys, electronic keying allows the ControlLogix system to control what modules belong in the various slots of a configured system. During module configuration, you must choose one of the following keying options for your 1756-SYNCH module: • Exact Match • Compatible Match • Disable Keying When the controller attempts to connect to and configure a 1756-SYNCH module (e.g.
3-12 SynchLink Module Features Table 3.6 describes the keying options available with your 1756-SYNCH module. Table 3.6 Keying option: Definiton: Exact Match All of the parameters listed above must match or the inserted module will reject a connection to the controller. Compatible Match The Compatible Match mode allows a 1756-SYNCH module to determine whether it can emulate the module defined in the configuration sent from the controller.
SynchLink Module Features 3-13 The Electronic Keying feature is configured on the following screen. Electronic Keying Requested Packet Interval The Requested Packet Interval (RPI) is a configurable parameter that defines when the module multicasts its data onto the local chassis backplane. In the SynchLink module, though, the RPI’s role is dictated by the data the SynchLink transfers. Axis Data The RPI does not have an effect on produced or consumed axis data.
3-14 SynchLink Module Features Buffered, Direct and Diagnostic Data - RPI Effect on Input Data (to the controller) The RPI is one of two mechanisms available through the 1756-SYNCH module to update the module’s input data onto the backplane. Input data is transferred from the SynchLink module to its owner-controller at the rate defined in the RPI.
SynchLink Module Features 3-15 SynchLink Transmitted Axes Most applications using the ControlLogix SynchLink module use it for Remote Axis Control. You can use the SynchLink module to produce axes from a master chassis and broadcast the data to other chassis. The module can produce and consume two axes (i.e. Axis 0 & Axis 1). Slave chassis consume the broadcast axis data and redistribute it to their local motion planners (i.e. the Logix controller in their local chassis).
3-16 SynchLink Module Features Transmitted Direct Words The SynchLink module can transmit data from the following direct word sources: • Output Direct Words (0-3) • Received Direct Words (0-3) • Multiplier In initial configuration, you can choose the Transmitted Direct Words, but you must use ladder logic to move data to those locations in data type tags. For more information on the data tags, see Appendix E. Direct Words Direct words are data delivered in a single message.
SynchLink Module Features 3-17 The multiplier can only transmit the same word it received (i.e. this feature does not allow your module to receive direct word 0 and transmit it as direct word 1). The multiplier output is limited to 16 bits; any value generated by the multipler larger than 65535 is truncated to 16 bits, and a multiplier overflow error (described below) is reported by the Synchlink module.
3-18 SynchLink Module Features CST and SynchLink Mastership The SynchLink module can be configured for multiple mastership and slave roles in respect to the Coordinated System Time and the SynchLink. Table 3.7 describes the ways you can configure your 1756-SYNCH module’s role in CST Mastership. Table 3.7 Possible SynchLink Configurations This configuration: Only the Make SynchLink CST Master box is checked. Means: • This module relays time from the Chassis CST Master to the SynchLink.
SynchLink Module Features 3-19 Table 3.7 Possible SynchLink Configurations This configuration: Means: Dependence on SynchLink is Not Required • The module is a Time Slave on SynchLink. • The module is the CST Time Master of the local chassis. • You MUST have selected another module on the fiber optic cable to be the SynchLink CST Master. • If your 1756-SYNCH module uses firmware revision 2.

Appendix E Software Configuration Tags IMPORTANT Although this appendix presents the option of changing a module’s configuration through the Tag Editor of RSLogix 5000, we suggest that you use the module’s properties tabs to change configuration when possible. When you create a module, module-defined data types and tags are created in the RSLogix 5000 programming software. These Tags allow you to access the Input and Output Data of the module via the controller’s ladder logic.
E-2 Software Configuration Tags Accessing the Tags When you access tags, you have two options. You can: • monitor tags - option allows you to view tags and change their values • edit tags - option allows you to add or delete tags but not change values A. Right-click on Controller Tags. B. Select Monitor Tags. You can view tags here. Click on the data type (input or output) you want to see. Information is listed for each input and output data type.
Software Configuration Tags Configuration Data Tags E-3 Table E.1 lists the configuration data tags available on your 1756-SYNCH module. These tags control the configurations described in Table 3.7 on page 3-18. Table E.1 Configuration Data Tags Name Type: Definition: Local:x:C.ChassisCSTMst BOOL If this bit is set to 1, the module becomes the CST master for its chassis. Local:x:C.SLCSTMst BOOL If this bit is set to 1, the module becomes the CST master for the entire SynchLink. Local:x:C.
E-4 Software Configuration Tags Table E.2 Input Data Tags Name Type: Definition: BOOL 0 = Valid CST data received from upstream module or CST data not required (x = module’s chassis slot location): Local.x.I.SynchLinkCSTFault 1 = This module configured to relay CST from SynchLink to Chassis and valid CST data not received from upstream module Local.x.I.
Software Configuration Tags E-5 Table E.2 Input Data Tags Name Type: Definition: BOOL 0 = The module’s transmit port is transmitting Axis0 data or is not configured to transmit such data. (x = module’s chassis slot location): Local.x.I.TxAxis1Fault 1 = The module is configured to transmit Axis0 data but is experiencing a fault on that port. Local.x.I.DirectData[0] through Local.x.I.DirectData[3] DINT These 4 fields vary according to the data contained in the direct words the module receives.
E-6 Software Configuration Tags Notes: Publication 1756-UM521C-EN-P - July 2004
Glossary Buffered data Data exchanged between SynchLink nodes. The data is appropriately segmented at the transmitting module and reassembled at the receiving module. Buffered data cannot be automatically forwarded to the next node in the daisy chain configuration. Center node A node in the SynchLink Daisy Chain or Ring configuration that receives data and transmits data. Communications format Format that defines the type of information transferred between an I/O module and its owner controller.
Glossary 2 Daisy chain configuration SynchLink configuration that begins with a master node and ends at an end node. Center nodes may be used between the master and end in this configuration. Direct data Data delivered in a single message. A SynchLink message can allocate a maximum of four words. Direct data can be automatically forwarded to the next node in the daisy chain configuration. Disable keying Option that turns off all electronic keying to the module.
Glossary 3 Inhibit A ControlLogix process that allows you to configure a SynchLink module but prevent it from communicating with the owner controller. In this case, the controller does not establish a connection. Hub Distribution unit in the star configuration that consists of a single base block and up to 4 splitter blocks. Unidirectional data passes through the hub. Listen-only connection An I/O connection that allows a controller to monitor I/O module data without owning the module.
Glossary 4 Remote axis data Motion data used by the motion planner in the controller. The 1756-SYNCH module can consume an Axis tag from a controller and pass it over SynchLink. A controller in another chassis can then consume axis tags passed over SynchLink from the 1756-SYNCH module in that chassis. Removal and insertion under power (RIUP) A ControlLogix feature that allows a user to install or remove a module while power is applied.
Glossary 5 Synchronize A process where multiple devices operate at the same time or maintain a matching time reference. Time master A device (e.g. SynchLink module) that is configured to establish the time reference for a ControlLogix chassis or SynchLink system. Time relay A device that is configured to pass a time reference between a chassis backplane and a SynchLink fiber. Time slave A device (e.g.
