Modbus TCP nomenclature is the same as for the Modbus over Serial line protocol, as any device which send out a Modbus command, is the 'client' and the response comes from a 'server'. [29] The ADU for Modbus TCP is officially called Modbus TCP/IP ADU by the Modbus organization [30] and is also called Modbus TCP frame by other parties. [3]
EtherCAT (Ethernet for Control Automation Technology) is an Ethernet-based fieldbus system developed by Beckhoff Automation. The protocol is standardized in IEC 61158 and is suitable for both hard and soft real-time computing requirements in automation technology.
Here we find the solutions Ethernet/IP, three versions of PROFINET IO - the classes A, B, and C - and the solutions of P-NET, [28] Vnet/IP [29] TCnet, [30] EtherCAT, Ethernet POWERLINK, Ethernet for Plant Automation (EPA), and also the MODBUS with a new Real-Time Publish-Subscribe MODBUS-RTPS and the legacy profile MODBUS-TCP.
The PowerPC 970 ("G5") was the first 64-bit Mac processor. The PowerPC 970MP was the first dual-core Mac processor and the first to be found in a quad-core configuration. It was also the first Mac processor with partitioning and virtualization capabilities. Apple only used three variants of the G5, and soon moved entirely onto Intel architecture.
Allows three bit rates: 125 kbit/s, 250 kbit/s and 500 kbit/s, the main trunk under different bit rates (trunk) is inversely proportional to the length and bitrate; Flat cable network can be used; Single network can have up to 64 nodes, node address (called MAC ID in DeviceNet) by 0–63.
Mac OS X 10.4.7 and higher versions of Mac OS X 10.4 run 64-bit command-line tools using the POSIX and math libraries on 64-bit Intel-based machines, just as all versions of Mac OS X 10.4 and 10.5 run them on 64-bit PowerPC machines. No other libraries or frameworks work with 64-bit applications in Mac OS X 10.4. [99]
Older machines that are unable to run the 64-bit kernel run the 32-bit kernel, but, as with earlier releases, can still run 64-bit applications; Lion does not support machines with 32-bit processors. Nearly all applications bundled with Mac OS X 10.7 are now also 64-bit, including iTunes. [citation needed] 2012
