MLC Connectivity to SLC 500 via DeviceNet
Equipment Needed for Connecting
MLC 9000 BCM Allen-Bradley SLC 500 CPU 5/02 or higher
– 5/02 smallest CPU to support M0/M1 File Transfer Allen-Bradley 1747-SDN DeviceNet Scanner Allen-Bradley RSNetworx or DeviceNet Manager Software RSLogix PLC Programming Software PC Interface(i.e 1770-KFD for programming) DeviceNet Cabling
– Thick Trunk Cable with Mini-Connectors– Thin Drop Cable with Micro or Mini-Connectors– T-Connectors– Terminating connectors(110 Ohms)
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
How SLC 500 Communicates with 1747-SDN
Block Transfer via M0/M1 Files– M1 File
150 Words Available for Input from Network Devices (M1:1.0-M1:1.149)
74 Diagnostic Words (M1:1.150-M1:1.223) 32 Words for Inbound Explicit Message Control
(M1:1.224-M1:1.255)
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 (M0:1.0-M0:1.149)
74 Words Reserved/Unused (M0:1.150-M0:1.223) 32 Words used for outgoing explicit message
control (M0:1.224-M0:1.255)
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
