Signal Controller Data The SPM Service shall have the capability of collecting, storing, and analyzing high -resolution (10 Hz) signal controller data from controllers that log this data in the industry -standard format. This list of controllers includes: • Siemens o M50 Linux & M60 ATV • ECOM v3.52+ • NTCIPv4.53+ • Econolite o Cobalt —Any version o ASC3 NEMA—v2.S0+ & OS 1.14.03+ 0 2070 with IC CPU Module — v32.50+ • Intelight Maxtime—v1.7.0+ • McCain ATC Omni eX1.6+ • Peek ATC Greenwave—v03.05.0528+ • Trafficware 980ATC v76.10+ Data Acquisition and Transmission The following is required for data acquisition and transmission: • List of controller IP addresses and port numbers • Outbound access from the SPM data collection server to field controllers via port 161 (UDP) or other designated port.
