ATOP Serial Servers, Protocol Gateways and Substation Networking
IndustrialComms is a UK distributor of ATOP Technologies, the Taiwanese manufacturer of industrial networking and serial communication equipment. With over 30 years in the market and its own manufacturing facility, ATOP builds hardware for power substations, rail and trackside, oil and gas, marine and factory automation networks.
ATOP's substation range is certified to IEC 61850-3 and IEEE 1613, with rack-mount modular switches supporting PTP boundary and transparent clock roles. The NTS86X0 grandmaster clock series is the first to hold both IEC 61850-3 HV and IEEE 1613 certification, delivering sub-microsecond synchronisation for digital substation networks. Rail products are certified to EN 50155 and EN 50121-4, with IP67 and M12 variants for rolling stock and trackside cabinets. ATOP products carry UL, CE, FCC, RoHS, IEC 62443 and TAA compliance.
