Chapter 3 Configuration & Interfacing Discrete Input Bit Specifier (Par #519) – This parameter determines which bit of the parameter specified by the Discrete Input Map will be affected by the discrete input. Jumper J4, 115V AC/24V DC select – This jumper allows the selection of the input voltage required to operate the discrete input. Refer to Table 3–B. Discrete Input Operator (Par # 520) – Determines how the discrete input will affect the bit specified by the Discrete Input Bit Specifier.
Chapter 3 Configuration & Interfacing Figure 3-3. Constant Parameter Example MCA Board Input 504 550 Constant #1 550 1000 Multiply #1 Block By placing the constant #1 parameter number (Par #550) into the input parameter (Par #504) the data value of 1000 in constant parameter (P #550) is used as the input to the Multiply 1 block.
Chapter 3 Configuration & Interfacing Multiply Block #1 General Description – This block (Fig. 3–5) receives an input (parameter 504) and multiplies it by a gain value (parameter 505). The output can be linked to other Drive parameters or used by the MCA board with other function blocks. The overflow control parameter (parameter 517) determines the fault type and action taken when an overflow condition occurs. Figure 3-5.
Chapter 3 Configuration & Interfacing Overflow Control (Par # 517) – This parameter determines what action the Drive will take when a Block Output value overflow condition occurs. Refer to Table 3–E for details. Table 3-E.

Chapter 3 Configuration & Interfacing Add Block General Description – The Add block (Figure 3–7) sums up to three external values (parameters 508, 510, 512) and one offset value (parameter 514) to obtain a result. Each external input has a scale factor (parameters 509, 511, 513) that is independently programmable. The output (Par 318) can be linked to other Drive parameters or used by other MCA function blocks.
Chapter 3 Configuration & Interfacing Parameter Description: Block Output (Par # 318) – This is a fast source parameter which contains the result of the addition. The data can be used on the Adapter or passed to the Drive by using a Drive configuration link. Block Input #1 (Par # 508) – A parameter that specifies where this block gets one of the input values used in the addition process. Input data can come from other functions on this Adapter or from the Drive by using CA Indirect parameters.
Chapter 3 Configuration & Interfacing Low Pass Filter This block is a first order low pass filter which can be used to filter inputs. The equation for this filter is shown below. This block receives an input (parameter 515) and multiplies it by a filter gain value (parameter 516). The output can be linked to other Drive parameters or used by other MCA function blocks. The equation for this filter is: Ynew= Yold + (Input – Yold) * Gain. Figure 3-8.
Chapter 3 Configuration & Interfacing RIO Communications Each channel of the MCA board can be configured for Allen-Bradley Remote I/O (RIO) communications. Configuration as a RIO device allows the Drive to look like a remote I/O chassis to a PLC. The MCA board has several features, some of which are not available with the Node Adapter board. This adapter can replace the Node Adapter board in applications where these additional communications features are required.
Chapter 3 Configuration & Interfacing Discrete PLC Controller I/O Data Transfer Data required by the Drive on a continuously updated basis is transferred using the I/O image table of the PLC Controller. The data transfer rate can be determined using the standard conventions for I/O rack updates of discrete I/O. Refer to the PLC Controller manual for details. Refer to Figures 3–9 thru 3–11. These figures indicate how data is transferred between the Drive and PLC controller for the rack size selected.
Chapter 3 Configuration & Interfacing Figure 3-11. RIO Half Rack Configuration Configured as 1/2 Lower Rack Group 0 Group 1 Group 2 Group 3 Configured as 1/2 Upper Rack Group 4 Reserved for Block Transfer Group 5 Group 6 Group 7 Each group appears to have a 16 bit input and output module installed. Figure 3-12.
Chapter 3 Configuration & Interfacing Discrete PLC Controller I/O Example Figure 3–13 illustrates an application where the MCA Board has been setup for a full rack (numbered rack 2) and the 16 bit words for group 1 and 2 are being used by the PLC Controller program for data transfer with the Drive. In this example, the Drive has been configured so that the data coming into source parameter 307 is sent to Logic Cmd 1 (parameter 150).
Chapter 3 Configuration & Interfacing Figure 3-13.
Chapter 3 Configuration & Interfacing Figure 3-14.
Chapter 3 Configuration & Interfacing Bit numbering in the PLC Controller is performed in Octal, as opposed to Decimal numbering in the Drive parameter 150, so it is necessary to relate the output image table bits to the controlled bits in parameter 150. Figure 3–15 shows the correlation between the output image table bits and the Drive parameter 150 bits.
Chapter 3 Configuration & Interfacing If the normal run speed reference is selected, the PLC Controller must send a 16 bit word to External Vel Ref (parm 154) in the Drive. Because the speed reference is a complete 16 bit word, the PLC Controller must send the data as a complete word rather than as individual bits as was the case for logic command bits. In this example, word 1 of integer file N10 is used to store the speed reference for the Drive.
Chapter 3 Configuration & Interfacing Message Structure Figure 3–16 illustrates the message structure required by the block transfer (BTW or BTR) function in the PLC Controller. The message is segmented into 16 bit words. The first four words, commonly called the message header, must be present. The data portion of the message is only required for those functions that contain or require data. The following paragraphs provide a description of each word: Figure 3-16.

Chapter 3 Configuration & Interfacing Word 4, High byte – This byte contains the block transfer status byte (see Table 3–L) which is a code number returned from the MCA board as a response to the block transfer function. This byte is not used by the PLC Controller when sending data to the Adapter and therefore is set to 0 when performing a block transfer write in the PLC Controller program. Table 3-L.
Chapter 3 Configuration & Interfacing MCA Status Word The status word is returned from the MCA Board to the PLC Controller in addition to the Block Transfer Status Byte (Word 4, high byte). The MCA status word appears as the first slot (or word) in the rack assigned to the Multi-Communications Adapter (Refer to Figure 3–17). This status byte indicates the condition of the MCA itself and is not included as part of the PLC Controller block transfer instruction.
Chapter 3 Configuration & Interfacing Block Transfer Write in Process – Is set when a block transfer write to the Drive is in process. This bit remains set until the message has been received and placed in the Drive’s internal message buffer. IMPORTANT: Do not attempt to initiate another block transfer request while this bit is set. The Drive will not respond to the request. Block Transfer Read Data Available – Is set when the Drive has data available for the PLC to read.
Chapter 3 Configuration & Interfacing Group: – The group number of the first in the group in the rack as specified above. If the Drive is setup as a 3/4 rack, the first group could be 0 or 2. If the Drive has been setup as a full rack, group number is 0. If the Drive is setup as a half rack, the first group number could be 0 or 4. Refer to Figures 3–9 through 3–11 for details. Module: – The module number associated with the block transfer function in the first group. This is always set to 0.
Chapter 3 Configuration & Interfacing RIO Redundant Mode The RIO redundant mode is a special mode that allows the Drive to be connected to the RIO channel of two separate PLC Controllers. A parameter in the Drive specifies which PLC Controller has control of the Drive. Output image table data from the non-controlling PLC is discarded. Figure 3–19 shows a typical redundant mode configuration. The redundant RIO mode is only available when the following three conditions are met: 1.
Chapter 3 Configuration & Interfacing Figure 3-19.
Chapter 3 Configuration & Interfacing DH+ Communications Each channel of the MCA board can be configured for Data Highway + (DH+) communications. Configuration as a DH+ device allows the Drive to look like a station on the DH+ link. Below is a listing of the DH+ features on this Adapter: S The Adapter supports 57.6K, 115K, and 230K baud communication rates. S Supports Parameter read and parameter write messages for blocks of parameters.
Chapter 3 Configuration & Interfacing PLC Typed Read (N11:499–999) – This request reads the status of the previous parameter writes (N10:500–999). If a Typed Read is specified with an PLC address of N11:499, the write status of all parameters from the last TYPED WRITE request (N10: xxx–xxx) will be OR’ed together. If one error has occurred during the last write operation, this address will contain the parameter number where the error occurred.
Chapter 3 Configuration & Interfacing Token Pass With Data This is a special mechanism built into the MCA board that allows the Drive to transfer data between stations on a DH+ link along with the link token. Refer to Figure 3–20. The amount of information passed is limited as follows: S Each station (each channel of an MCA board) can add two parameters values to the list of values transferred with the token.

Chapter 7 Periodic Maintenance Preventative Maintenance WARNING: Servicing energized industrial equipment can be hazardous. Severe injury or death can result from electrical shock, burn, or unintended actuation of controlled equipment. Recommended practice is to disconnect and lock out control equipment from power sources, and allow stored energy in capacitors to dissipate, if present.
Chapter 7 Periodic Maintenance Periodic Inspection – Industrial control equipment should be inspected periodically. Inspection intervals should be based on environmental and operating conditions, and adjusted as indicated by experience. An initial inspection within 3 to 4 months after installation is suggested.
Chapter 7 Periodic Maintenance Tests & Records Final Check Out – After maintenance or repair of industrial controls, always test the control system for proper functioning under controlled conditions that avoid hazards in the event of a control malfunction. “Keep Good Maintenance Records” – This rule will be most helpful in locating possible intermitttent problems by pointing to a particular area of recurring trouble within the overall system.
