SLC 5/03 Processor
Hardware Features The SLC 5/03 processor offers:
• program memory size of 8 K, 16 K, 32 K.
• control of up to 4096 input and output points.
• online programming (includes runtime editing).
• built-in DH-485 channel.
• 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 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 (Serves as a second DH-485 channel. Use a
1761-NET-AIC interface with a 1747-CP3, 1761-CBL-AC00, or
1761-CBL-AP00 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-485 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.
• 2 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
(SLC 5/03 OS302 processor or later).
• multi-point list (SLC 5/03 OS302 processor or later).
• UL listed to US and Canadian Safety Standards, CE compliant,
C-Tick marked.
