Edit the RS485 DF1 parameters using the same techniques as for drive parameters. Figure 4.1 Accessing the Module Parameters using the LCD OIM 4.3 Setting the Node Address If the Data Rate switch on the module is set to PGM, the value of module parameter 3 (DF1 Addr Cfg) determines the node address. Step 1. Set the value of module parameter 3 (DF1 Addr Cfg) to a unique node address. Port 5 Device RECOMM-485 Parameter #: 3 DF1 Addr Cfg 1 0 <> 99 Default = 1 Figure 4.2 RS485 DF1 Node Address Screen on an LCD OIM Step 2. Reset the module. Refer to section 4.7.2, Resetting the Module. 4-2 RS485 DF1 Communications Module

25 4.4 Setting the Data Rate If the Data Rate switch on the module is set to PGM, the value of module parameter 5 (DF1 Rate Cfg) determines the RS485 DF1 data rate. Your application may require a different setting. Step 1. Set the value of module parameter 5 (DF1 Rate Cfg) to the data rate at which your network is operating. Refer to figure 4.3. Port 5 Device RECOMM-485 Parameter #: 5 DF1 Rate Cfg bps Value Baud Rate bps bps bps bps (default) kbps kbps Figure 4.3 Data Rate Screen on an LCD OIM Step 2. Reset the module. Refer to section 4.7.2, Resetting the Module. 4.5 Setting the Error-Checking Method Two types of error-checking methods are used with the DF1 protocol: Cyclic Redundancy Check (CRC) and Block Check Character (BCC). (Refer to the Glossary for a description of each method.) Step 1. Set the value of module parameter 24 (CRC/BCC) to the method used by the network as shown in figure 4.4.

Refer to section 4.7.2, Resetting the Module. Configuring the RS485 DF1 Module 4-3

26 4.6 Setting the I/O Configuration The I/O configuration determines the type of data sent to the drive. This is a two-part process: enabling/disabling the data transmitted between the module and the drive, and identifying the data transmitted between the module and the master (i.e., scanner). Step 1. Enable or disable the data transmitted between the module and the drive by setting the bits in module parameter 12 (DPI I/O Config). A 1 enables the I/O. A 0 disables the I/O. Bit 0 is the right-most bit. In figure 4.5, it is highlighted and equals 1. Port 5 Device RECOMM-485 Parameter #: 12 DPI I/O Config xxxxxxxxxxx Cmd/Ref b00 Bit Description 0 Logic Command/Reference (Default) 1 Datalink A 2 Datalink B 3 Datalink C 4 Datalink D 5-15 Not Used Figure 4.5 I/O Configuration Screen on an LCD OIM Step 2. Step 3. Step 4. If Logic Command/Reference is enabled (default), configure the parameters in the drive to accept the Logic Command and Reference from the module. For example, set Speed Ref A Sel (SP600 drive parameter 90) to Network so that the drive uses the Reference from the module. Also, verify that SP600 drive parameter 89 (Logic Source Sel) is configured to receive the desired logic from the module. If you enabled one or more Datalinks (optional), configure parameters in the drive to determine the source and destination of data in the Datalink(s). Also, ensure that the RS485 DF1 module is the only module using the enabled Datalink(s). Reset the module. Refer to section 4.7.2, Resetting the Module. The module is ready to receive I/O from the master (i.e., scanner). You must now configure the scanner to recognize and transmit I/O to the module. 4-4 RS485 DF1 Communications Module

27 4.7 Setting a Fault Action By default, when communications are disrupted (for example, a cable is disconnected) or the scanner is idle, the drive responds by faulting if it is using I/O from the network. You can configure a different response to communication disruptions using module parameter 10 (Comm Flt Action).! ATTENTION: Module parameter 10 (Comm Flt Action) lets you determine the action of the module and connected drive if communications are disrupted. By default, this parameter faults the drive. You can set the parameter so that the drive continues to run. Precautions should be taken to ensure that the setting of this parameter does not create a risk of injury or equipment damage. Set the value of module parameter 10 (Comm Flt Action) to the desired response as shown in table 4.2. See figure 4.6 for a sample LCD OIM Fault Action screen. Table 4.2 Selections for Drive Response to Communication Fault Value Action Description 0 Fault (default) The drive is faulted and stopped (Default). 1 Stop The drive is stopped, but not faulted. 2 Zero Data The drive is sent 0 for output data after a communications disruption. This does not command a stop. 3 Hold Last The drive continues in its present state. 4 Send Flt Cfg The drive is sent the data that you set in the fault configuration parameters 14 through 23 (Flt Cfg Logic through Flt Cfg D2 In). Port 5 Device RECOMM-485 Parameter #: 10 Comm Flt Action 0 Fault Figure 4.6 Fault Action Screen on an LCD OIM Changes to this parameter take effect immediately. A reset is not required. Configuring the RS485 DF1 Module 4-5

28 4.7.1 Setting the Fault Configuration Parameters If you set module parameter 10 (Comm Flt Action) to Send Flt Cfg, the values in the parameters shown in table 4.3 are sent to the drive after a communications fault occurs. You must set these parameters to values required by your application. Table 4.3 Fault Configuration Parameters Parameter Number Name Description 14 Flt Cfg Logic A 16-bit value sent to the drive for Logic Command. 15 Flt Cfg Ref A 32-bit value (0 to ) Flt Cfg x1 In sent to the drive as a Reference Flt Cfg x2 In or Datalink. Important: If the drive uses a 16-bit Reference or 16-bit Datalinks, the most significant word of the value must be set to zero (0) or a fault will occur. Changes to these parameters take effect immediately. A reset is not required Resetting the Module Changes to switch settings or some module parameters require that you reset the module before the new settings take effect. You can reset the module by cycling power to the drive or by using module parameter 9 (Reset Module).! ATTENTION: If the module is transmitting control I/O to the drive, the drive may fault when you reset the module. Determine how your drive will respond before resetting a connected module. Failure to observe this precaution could result in bodily injury or damage to equipment. 4-6 RS485 DF1 Communications Module
