Alicat devices are compatible with a variety of analog, serial, or industrial communication protocols for easy data collection and analysis. Options include analog (4-20 mA, 0-10 Vdc, 0-5 Vdc, or 1-5 Vdc), ASCII and Modbus RTU over RS-232, ASCII and Modbus RTU over RS-485, PROFIBUS, PROFINET, DeviceNet, EtherNet/IP, Modbus TCP/IP, and EtherCAT.
In this article, we provide answers to common questions about PROFINET.
Find supporting downloads such as the certificates of conformity, manual, and GSD files here. Note that the GSD file for M, L, and P series products is different from the one for CODA (K and KC series) products.
PROFINET is available on most Alicat mass flow and pressure devices, including M, L, and P series instruments, and the CODA K series Coriolis mass flow instruments.
Exceptions (incompatible with PROFINET):
Standard PROFINET devices are powered through a power jack, while PROFINET devices rated to IP66 and IP67 are powered through an M8 connector.
Yes, where those choices are already provided. Gas instruments with PROFINET have their full Gas Select™ list of gas calibrations and Composer™ gas mixing firmware. CODA Coriolis instruments, that do not natively have Gas Select, will not gain Gas Select when PROFINET is added – and it would be of no benefit, in any case, since CODA is accurate for mass flow, independent of the species flowing.
PROFINET uses a full-duplex Ethernet hardware layer for data rates up to 1 Gbit/s—but communication speeds are limited by cable class. Also, bear in mind that data throughput is divided across the full network’s number of nodes.
They are located on the case top of instruments that are rated lower than IP 6/6 or IP 6/7. They are additional to the LEDs that are built into the RJ45 connectors. We provide NET and READY LEDs for debugging PROFINET device status. They indicate basic open, closed, or active circuits for ensuring power-up and connections to a network.
IP 6/6 and IP 6/7 devices do not have indicator lights.
No. PROFINET can only be assembled and installed on new instruments due to distinct hardware and firmware requirements.
Yes, PROFINET instruments are certified compliant by PROFIBUS Nutzerorganisation e. V.
