• The CERI .
• maintains a set of (4x) data registers mapped to
  the A120 Compact I/O
• scans the rack continually and updates these
  registers
• services the TCP messages at the end of each rack
  scan
• PLC I/O Scanner readswrites this data on
  Modbus/TCP Index 0 or 1

Rack Mapper

• 10,000 words of Holding Registers (4x)
• Accessed as Modbus/TCP Index 0 or 1
• Accepts Modbus/TCP function codes 3, 6, 16, and
  23
• Mapper associates these Holding Registers to
  Inputs and Outputs on the rack.
• Group all of the Inputs together (and Outputs) so
  a single I/O Scanner entry covers the entire CERI
• Mapper automatically expands multiplexed modules
• Internal CERI configuration and status registers
  may also be mapped to the I/O registers
• Each Output word has a default value on watchdog
  failure
• 4-bit and 8-bit modules are mapped as a single
  word (LSB)
• Mapper can reverse I/O bit orders and can pack
  and unpack both nybbles and bytes for proper bit
  number alignment
