⋆ 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.
