SLC Processors
SLC ProcessorsThe SLC processors offer a wide range of choices in memory, I/O capacity, instruction set, and communication ports to allow you to tailor a control system to your exact application requirements. These products have a strong reliability history covering hundreds of thousands of installations in a broad range of applications.
SLC 5/01 processors let you configure modular controllers of up to 960 I/O and a 1K- or 4K-instruction memory capacity.
SLC 5/02 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs nominally and a 4K-instruction memory. By installing an optional scanner module into one of the 30 I/O module slots, you can add ControlNet I/O, DeviceNet I/O, or Universal Remote I/O to the system. They offer 19 additional instructions, including a message instruction for initiating peer-to peer communication.
SLC 5/03 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs and a memory of 8K, 16K, or 32K words. In addition to the features of the SLC 5/02, they have a second built-in communication port—an RS-232-C port that can be configured for ASCII or DF1 protocol, and can be configured for connection to a 1761-NET-AIC converter to provide access to a DH-485 network. SLC 5/03 processors provide bit-instruction execution times of 0.44 ms and an overall system throughput of up to 10 times faster than competitive processors. Additional capabilities include: floating-point math, online programming and run-time editing, flash memory upgrades, built-in key-switch, and a built-in real-time clock and calendar.
SLC 5/04 and 5/05 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs and a memory of either 16K, 32K, or 64K words. They have all the features of the SLC 5/03 processors, plus a faster communication port and shorter execution times (bit-instruction execution times of 0.37ms). Instead of a DH-485 port, the SLC 5/04 has a built-in DH+ port for communication with other SLC 5/04 and PLC processors, operator interfaces, and programming terminals. Communication via the DH+ network is three times faster than DH-485 communication. SLC 5/05 processors provide a 10/100BASE-T, 10 or 100 Mbps Ethernet port.

| ⋆ Modbus slave protocol is embedded in the RTU-5/03 processors available from an Encompass partner. The Modbus slave protocol is supported on the RS-232 port (channel0). For information on the Encompass program visit: www.rockwellautomation.com/encompass/. ‡ The absolute maximum number of I/O for these processors only reflects the I/O addressing capability. It does not take into account the amount of memory that may be required for a ladder-logic program to monitor and control the I/O. The practical ratio of memory per I/O is totally dependant upon your specific application. § You cannot configure this number of I/O for these processors with local I/O only. To configure this number of I/O for these processors, you must add a 1747-SN Remote I/O Scanner module to configure I/O on a Universal Remote I/O link, add a 1747-SDN DeviceNet Scanner module to configure I/O on a DeviceNet network and/or add a 1747-SCNR ControlNet Scanner module to configure I/O on a ControlNet network. ♣ The 5/05 Series C processors can communicate to 100 Mbps and support increased Ethernet connections: 1747-L551=32 connections; 1747-L552=48 connections; 1747-L553=64 connections. |

| ⋆ With this processor, you can also install a 1747-SN Remote I/O Scanner module to configure I/O on a Universal Remote I/O link and/or add a 1747-SDN DeviceNet Scanner module to configure I/O on a DeviceNet network. You can configure 32 I/O chassis per Universal Remote I/O scanner using complementary I/O. If you don’t use complementary I/O, you can configure 16 I/O chassis per Universal Remote I/O scanner. With the DeviceNet scanner, you can address a maximum of 63 DeviceNet devices over the DeviceNet network. ‡ An SLC 5/01 processor can only receive messages and send reply messages to command messages sent from other nodes on the DH-485 network; it cannot initiate communication. § The SLC 5/03 has an RS-232 port, which can also be configured for a DH-485 network, enabling the SLC-5/03 to connect to two DH-485 networks simultaneously. ♣ The SLC 5/04 and SLC 5/05 have an RS-232 port, which can also be configured for a DH-485 network. ∆ SLC 5/04 processors manufactured prior to April 2002 draw 200 mA @ 24V DC. Check the processor label to verify current draw. |
