Telegram recording in Ethernet-based networks during running production

The PNMA II provides nonreactive access for telegram recording in the PROFINET and other Ethernet-based networks during running production.

PROFINET measuring point PNMA II Features

    • If connecting a PROFINET-INspektor® NT via a PNMA II, only two additional patch cables are needed (no crossover cable required).
    • In case of a power supply failure the PROFINET communication via the PNMA II remains intact.
    • Power supply of additional analytic tools via the UOUT (24VDC) connector
    • PNMX IP 67 for rough production environments


Analysis tools (e.g. PN-INspektor® NT or laptop) can be connected nonreactive to the two monitor jacks to monitor both communication directions simultaneously. For evaluation of the measurement results the telegrams from both communication directions can be overlaid. The PNMA II / PNMX does not discard error telegrams. Instead, it forwards them.
