SLC 5/05 Processor
Hardware Features
The SLC 5/05 processors offer:
• program memory sizes of 16 K, 32 K, or 64 K.
• high-speed performance - 0.90 ms/K typical.
• control of up to 4096 input and output points.
• online programming (includes runtime editing).
• built-in 10/100Base-T Ethernet channel, supporting:
– high-speed computer communication using TCP/IP.
– messaging capabilities with SLC 5/05, PLC-5, and
ControlLogix processors on Ethernet.
– SNMP for standard Ethernet network management.
– BOOTP for optional dynamic IP address assignment.
• built-in RS-232 channel, supporting:
– DF1 full-duplex for point-to-point communication; remotely
via a modem, or direct connection to programming or
operator interface devices. (Use a 1747-CP3, 1761-CBL-AC00,
or 1761-CBL-AP00 cable for direct connection.).
– DF1 radio modem for radio modem (peer-to-peer)
communication.
– DF1 half-duplex master/slave for SCADA type
(point-to-multipoint) communication.
– DH-485 (Use a 1761-NET-AIC with a 1747-CP3 cable to connect to
the DH-485 network.).
– Modbus RTU Master communication with Modbus RTU slave
devices.
– ASCII I/O for connection to other ASCII devices, such as bar code
readers, serial printers, and weigh scales.
• Channel-to-channel passthru (Ethernet to DF1 full-duplex, DF1
half-duplex Master, DF1 radio modem, or DH-485).
• remote I/O and DeviceNet passthru.
• built-in real-time clock/calendar.
• 1 ms Selectable Timed Interrupt (STI).
• 0.50 ms Discrete Input Interrupt (DII).
• advanced math features - trigonometric, PID, exponential,
floating point, and the compute instruction.
• indirect addressing.
• logical ASCII addressing in PLC-5 type messages.
• flash PROM provides firmware upgrades without physically
changing EPROMS through the Ethernet port.
• optional flash EPROM memory module available.
• keyswitch - RUN, REMote, PROGram (clear faults).
• battery-backed RAM.
• additional instructions such as swap and scale with parameters
