1747-6.2
The SLC 5/03 processor offers the following:
• program memory size of 8K or 16K
• 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 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 with a 1747-CP3 cable to connect to the
DH-485 network.)
– ASCII I/O for connection to other ASCII devices, such as bar
code readers, serial printers, and weigh scales
• remote I/O 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
• 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 higher)
• multi-point list (SLC 5/03 OS302 processor or higher)
• UL listed, CSA approved, CE compliant
