Considerations When Configuring Remote I/ O Crossing Logical Rack Boundaries Logical Rack 0 Logical Rack 1 Scanner Configuration and Programming 5-67 The following sections contain information that you should understand before you configure your scanner’s G file. G File Considerations • You can only change the RIO configuration by modifying the G file while offline in your program file. Your application program cannot access the G file, nor can you access it while online with your programming device. However, your SLC control program can dynamically inhibit and uninhibit RIO devices via the M0 file. • RIO devices larger than 1 logical rack appear as multiple devices on the RIO link. Refer to the Crossing Logical Rack Boundaries section below. • The address and size of the devices you list in the G file must match the settings of each RIO device. You express remote I/O image boundaries in an even number of groups. For example, the 1747-ASB image can be any size from two logical groups up to 32 logical groups (four logical racks), in 2logical group increments.If the scanner image assigned to an adapter is greater than 8 logical groups (one logical rack), the image crosses logical rack boundaries. If the scanner image assigned to an adapter is less than 8 logical groups, it too can cross a logical rack boundary depending upon the starting logical group number. The significance of crossing logical rack boundaries is discussed in the next section. Examples of Crossing Logical Rack Boundaries Examples 1 and 2 that follow show adapters with logical image sizes that cross logical racks 0 and 1. The image size of the adapter in example 1 consumes all of logical rack 0 (eight logical groups) and half of logical rack 1 (four logical groups). The image size of the adapter in example 2 consumes two groups in logical rack 0 and four groups in logical rack 1.
