SLC 5/04 Processor
Hardware Features
The SLC 5/04 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 DH+ channel, supporting:
– high-speed communication (57.6 Kbaud, 115.2 Kbaud, and
230.4 Kbaud).
– messaging capabilities with SLC 500, PLC-2, PLC-5, and
ControlLogix processors.
• 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-AC00 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 (DH+ to DF1 full-duplex, DF1
half-duplex Master, DF1 radio modem, or DH-485).
• remote I/O passthru.
• 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.
• optional flash EPROM memory module available.
• keyswitch - RUN, REMote, PROGram (clear faults).
• battery-backed RAM.
• additional instructions such as swap and scale with parameters.
