1-32 Overview Logical Rack 0 Word 0 Word 1 Word 2 Word 3 Word 4 Word 5 Word 6 Word 7 Publication 1747-6.22 Complementary I/O Application Considerations If you configure a complementary device to use more I/O image space than an associated primary device, then block transfers can only be performed to locations in the complementary device that have associated I/O image space in the primary device. For example, if a primary device is 1/2 logical rack and a complementary device is a full logical rack, block transfers can be performed only in the first 1/2 logical rack of the complementary device. Attempting block transfers in the last half of the complementary device results in a BT error (error 11 - device not configured). 1/2 logical rack configured and usable 1/2 logical rack not configured Logical Rack 8 Word 0 Word1 Word 2 Word 3 Word 4 Word 5 Word 6 Word 7 Complementary 1771 I/O Module Details 1/2 logical rack configured and usable 1/2 logical rack configure but not usable for BT sin Words 4-7 are not configured for the primar device. Use the following modules in either primary or complementary I/O chassis opposite any type of module: • Communication Adapter Module (1771-KA2) • Communication Controller Module (1771-KE) • PLC-2 Family/RS-232-C Interface Module (1771-KG) • Fiber Optics Converter Module (1771-AF) • DH/DH+ Communication Adapter Module (1785-KA) • DH+/RS-232C Communications Interface Module (1785-KE) Use the following modules in either primary or complementary I/O chassis opposite any type of module. However, these modules do not work as standalone modules; each one has an associated master module. Use care when placing the master modules in the I/O chassis: • Analog Input Expander Module (1771-E1, -E2, -E3) • Analog Output Expander Module (1771-E4) • Servo (Encoder Feedback) Expander Module (1771-ES) • Pulse Output Expander Module (1771-OJ)
