Allen-Bradley SLC 500-Series controllers

New features of the Allen-Bradley SLC 500-Series controllers include improved messaging over Common Industrial Protocol (CIP)-based networks and enhanced security capabilities. Instruction updates allow generic CIP commands to be initiated in devices, such as drives, that communicate on Ethernet/IP, ControlNet and DeviceNet networks, simplifying the programming, configuring, monitoring and troubleshooting of explicit messages. A new firmware release includes a secured processor capability through Rockwell Software RSAssetSecurity, which enables the RSLogix 500 programming software to configure a processor so that it will be more secure against unauthorized access. A new Read Program Checksum (RPC) instruction can help determine whether online edits have changed the program or verify that the program in the memory module matches that in the processor’s RAM. And, a dynamic host configuration protocol (DHCP) provides flexible IP address assignment for the SLC 5/05 processor Channel One Ethernet port.
