FS-RA-CLX_SlotServer_Instruction_Manual_(T17011) 1. Page 4 of 34 Introduction 1.1. About this product The SlotServer Instruction Manual provides the information necessary to configure the SlotServer, allowing an Allen Bradley ControlLogix platform to pass data between a ControlLogix CPU and other third party communications protocols supported by the SlotServer. The SlotServer uses implicit communications between the CPU and the SlotServer and is consequently treated as an I/O Server in RSLogix.

CPU interface Description The SlotServer Data Images (Data Arrays) share data with the ControlLogix CPU tags using the backplane for communication and the FieldServer Logix driver. To map the Logix Driver, the Driver needs to be configured in the SlotServer Configuration. The information that follows details the configuration parameters that can be used for this driver.

Page 15 of 34 Programming the ControlLogix CPU for a small SlotServer Interface The discussion that follows describes the basic steps to set up and test the system for transferring data between CPU tags and the SlotServer using the I/O image method. The quick Start example uses LonWorks as the example 3rd Party Protocol. A hardcoded template is filled with Lon variables is created.

Choose the 1756-MODULE Choose the 1756-MODULE Be sure to choose the correct Slot number in the rack where your SlotServer reside Click Next and choose a RPI of 100 ms. This is the rate at which the I/O image data will be transferred FieldServer Technologies 1991 Tarob Court Milpitas, California 95035 USA Web:www.

Use the Input Image Data as Source. You can create the Destination Tag by right clicking on Destination and choosing New Tag. FieldServer Technologies 1991 Tarob Court Milpitas, California 95035 USA Web:www.
FS-RA-CLX_SlotServer_Instruction_Manual_(T17011) Page 18 of 34 Create a Controller Tag of Type REAL, dimension of 80 for the Destination • • Add an EQU (Compare if equal) ladder element to check when the first Data Array has been received. The block number is at offset 2 of the input image. Finally, add another CPS ladder element to copy the LonWorks Data from the InData_Copy Tag to a new Controller Tag, called Lon_In_01. Also create the Tag by right clicking on Destination and choosing New Tag.
FS-RA-CLX_SlotServer_Instruction_Manual_(T17011) Page 19 of 34 Below is the final ladder program to access data from LonWorks Function Block In[0] Very Important Note! It is very important to first make a synchronous copy of the input image data before using it. If this is not done, the input data cannot be guaranteed to be from a specific SlotServer Data Array.

Page 20 of 34 Step 4: Write Ladder Program to Send Output Data to Data Arrays This step demonstrates how to write data to the Data Array Out[0] • • • Create a Controller Tag called Lon_Out_01 of type REAL[80]. Add a new rung to the Ladder program and add a MOV element to move a block number value of 1 into Lon_Out_01[2]. Finally add a CPS (Synchronous Copy File) element to copy the full Lon_Out_01 tag into the Output Image Tag.
FS-RA-CLX_SlotServer_Instruction_Manual_(T17011) 8. Page 21 of 34 Programming the ControlLogix CPU for larger SlotServer Interfaces The previous example is for accessing only one Data Array. The following steps describe how to access multiple Data Arrays. 8.1. Multiple Input Data Arrays In this example, we access Input Data Arrays In[1] up to In[24]. We simply add to the existing ladder program as shown in the Quickstart example.
FS-RA-CLX_SlotServer_Instruction_Manual_(T17011) Page 22 of 34 It is possible to add up to 65535 blocks. The update rate decreases as the number of blocks goes up. For 25 blocks we have an update rate of 25*RPI = 25*0.1 = 2.5 seconds. You can restrict the upcount to a certain value, e.g.2 by changing the Preset value of the CTU element. Very Important Note! It is very important to only update all the data of the Output Image Tag once using a Synchronous File Copy element.

Description of Data Transfer Process The data connection from the SlotServer to the Logix CPU consists of 496 bytes of input and 496 bytes of output data. Of the 2 Map Descriptors specified, the one with the WRBC function writes data to the Logix CPU filling its input data, and the one with the RDBC function accepts the Logix CPU’s output data.

FS-RA-CLX_SlotServer_Instruction_Manual_(T17011) Page 26 of 34 Appendix A.4. Dealing with ControlLogix RPI Settings When setting up the SlotServer for ControlLogix, it is necessary to select the Request Packet Interval (RPI). The RPI is the rate at which data is transferred to and from the SlotServer IO buffers. The following factors need to be considered when deciding on an RPI: 1. Minimum RPI setting for the SlotServer is 100ms. 2.

Follow the prompts on the screen to configure the Chassis being used, and the cards in each Chassis (Rack). Go Online with RSNetWorx, and then press “save”. This will transfer the RSNetWorx Configuration to the Keeper.
FS-RA-CLX_SlotServer_Instruction_Manual_(T17011) Appendix A.5.5. Page 29 of 34 Testing The SlotServer should now be visible to the CPU. Go Online with RSLogix and check the Input buffer of the SlotServer for data. A good check is to examine offset 2 of the input tag for a non-Zero value. If the SlotServer is multiplexing (DA_Count >1), then this value will be cycling through the Buffer numbers, otherwise if DA_Count=1, then offset 2 will be fixed at 1.

Rules for Naming Logix driver Data Arrays Unlike most other FieldServer drivers, the Logix driver attaches significance to the name of the Data Array used in the Logix Driver Map Descriptor. This is done to allow the user to easily declare a series of Data Arrays to be multiplexed through the input and output buffers of the SlotServer.
