How SLC500 Communicates with 1747-SDN

• Two methods used
• I/O Transfer
• 1747 occupies 32 Input Words and 32 Output Words
• 1 word of input, 1 word of output used for module
  status and command
• 62 words available for devices
• Intended for devices transmitting small blocks of
  information
• Proximity and Photoelectric Switches
• Slice I/O
• Valves

4
How SLC 500 Communicates with 1747-SDN

• Block Transfer via M0/M1 Files
• M1 File
• 150 Words Available for Input from Network
  Devices (M11.0-M11.149)
• 74 Diagnostic Words (M11.150-M11.223)
• 32 Words for Inbound Explicit Message Control
  (M11.224-M11.255)

5
How SLC 500 Communicates to 1747-SDN

• Block Transfer via M0/M1 Files
• M0 File
• 150 Words of data used for output to network
  devices (M01.0-M01.149)
• 74 Words Reserved/Unused (M01.150-M01.223)
• 32 Words used for outgoing explicit message
  control (M01.224-M01.255)

6
How MLC 9000 Communicates with 1747-SDN

• MLC 9000 Gateway
• Converts DeviceNet Messages from Scanner into
  Modbus Messages to Bus Control Module
• Uses Polled Messaging for Implicit I/O Connection
• One Loop Control Module takes up 16 Bytes of
  Input and 6 Bytes of Output
• Uses Explicit Messaging to gain access to
  parameters not supported through implicit
  connection
