2500 Series Janus PAC 2020 AUGUST What is

2500 Series® Janus PAC 2020 -AUGUST

What is Janus? • Janus is the Roman god of bridges and transitions. Janus has two faces symbolizing his ability to look to both the past and the future. • Janus Programmable Automation Controllers (PACs) are designed to look to the past – to work seamlessly with existing Siemens/TI 505 and CTI 2500 Series® systems – as well as to look to the future with state-of-the-art programming, communications, and capabilities, including direct access to the Industrial Internet of Things (IIo. T) using MQTT. 2

2500 P-Jxxx “Janus” Processor – released May 8, 2020 • Programmed using Janus Workbench (“JSoft”), which allows use of RLL, FBD, ST, SFC and IL languages in programs – IEC-61131 Standards-based – Currently used for programming 2500 P-ACP 1 – Tag-based programming model – Similarity to Code. Sys, Step 7, and RSLogix means easier learning and better availability of System Integrators for projects • • Up to 10 x execution speed compared to current 2500 Series® CPU • • Web-based visualization of graphics pages designed in JSoft Built-in Remote I/O and Profibus interfaces with support for all existing 2500 Series® and Simatic® 505 discrete and analog modules Web server for diagnostic and statistics 3

2500 P-Jxxx “Janus” Processor • Four Ethernet ports support simultaneous connection to up to 4 different Ethernet networks • Extensive built-in communications capabilities: – High speed Data. Cache connection to existing CTI Cxxx processors – Optimized peer-to-peer communications with other JANUS processors and 2500 PACP 1 /2500 P-ECC 1 coprocessors (Network Data Exchange) – CAMP Client for communicating with all CTI Ethernet products (2572, 505 CP 2572, 2572 -A, 2572 -B, 2500 P-ECC 1, 2500 Series® CPUs) – CAMP Server for HMI/SCADA access – Open Modbus Client and Server – Ethernet/IP Scanner, Adapter, Tag Client, Tag Server – MQTT client for direct access to the IIo. T – OPC-UA server (future) – PROFINET controller and device (future) 4

A Tour of the Janus PAC LED status indicators Display for IP addresses, error messages External SD card for logging and other data files created Remote I/O port for compatibility with existing 2500 -Cxxx applications Four Ethernet ports, with up to four unique IP addresses and subnet masks for Programming, I/O, Communications, SCADA. Any port can do Modbus, PROFINET, Ethernet/IP, CAMP, MQTT, OPC-UA, etc Internal SD card contains operating system, firmware, and user program. Easily moved to a spare processor if needed. Profibus-DP port for compatibility with existing 2500 -Cxxx applications 5

Janus PAC Hardware Highlights • New ARM-based microprocessor + faster memory • Four Ethernet ports for maximum flexibility in operating SCADA and I/O networks – Up to four IP addresses are supported, with each on a different subnet • Internal and external SD cards – Internal card contains entire operating system, firmware, user program, configuration, user data (NOTE: This allows rapid replacement of a failed CPU simply by transferring the old SD card into the replacement unit) – External card for file exchange, firmware update, initial IP address assignment • Built-in Remote I/O and Profibus for compatibility with existing applications • Front accessible battery 6

Janus PAC Programming • Programming is done using Janus Workbench, an integrated development environment, which allows use of SFC, FBD, RLL, ST, IL in programs, and allows configuration of all communications within the same software • Complete backup of all program source files is downloaded to the PLC whenever an update is made (allows recovery of the complete application if the source files are lost) • Janus Workbench programs 2500 P-ACP 1 as well as new Janus PACs 7

Janus PAC Programming Features for Online Editing • Make any program changes needed (from simple to extensive) with Janus Workbench • Compile on PC • Go online with the CPU – Select “do online change” – Online change manager provides a summary of changes compared to the running program and gives user the ability to proceed or abort • If user selects “proceed”, at end of scan, processor syncs “old” database with “new” database and starts next scan using new program 8

Janus PAC Backward Compatibility Features • Support for local I/O, remote I/O and Profibus with configuration done in Janus Workbench – allows Janus to operate in all 2500 Series® and Simatic/TI 505 applications • Support of extensive communications capability on the CPU means that SF modules do not need to be supported • Support of special CTI “Data. Cache” protocol allows direct communication with existing CTI 2500 Series® Processors with updates guaranteed every scan • Existing HMI/SCADA devices can communicate with the PLC using CAMP. Variables can be named with valid “ 505” memory references or tagged with a 505 “pseudonym” like V 100. When the HMI polls for V 100, the CPU will return the value of the tag. • Conversion assistance for Workshop, TISoft, and APT™ Programs to Workbench 9

Janus PAC Security Features • “Secure Boot” process uses encryption keys to verify that the PLC is booting from the trusted CTI executable • Password protection for – – – connecting to the PLC with Janus Workbench for view / edit of individual programs for modifying PLC settings via web server for file management and firmware update functions for access to web visualization • Future security enhancements for encryption of communications 10
