6ES5544-3UB11
Siemens Simatic S5 CP554 Communications Module

Often referred to as the Siemens CP544B, the 6ES5544-3UB11 enables data to be transferred between your programmable controller (PLC) and other programmable controllers or computers via a point-to-point coupling.  When launched the 6ES5 544-3UB11 was the top of the range communications processor in the range of coupling modules fo the Simatic S5-115U, S5-135U and S5-155U programmable controllers. It is often used wherever the current coupling modules have reached their limits with respects to transmission speeds and protocol requirements.

The 6ES5 544-3UB11 provides

• 2 Flexible serial device interfaces which can be matched to the coupling partners via plug-in interface submodule.
• Transmission speed upto 76800 baud
• Use of a powerful interface chip for implementation of protocols for data transmission and telecommunications
• Integration of the most important transmission protocols; the parameter are stored in the internal RAM or in the user memory submodule of the CPU.
• Use of introduced transmission protocols of the point-to-point coupling of the CPU 928B
• Better adaption of transmision protocols through extended parameterization facilities
• Onboard PG Interface.
• Uniform parameteization interface for point to point coupling of the CP 544 and CPU 928B using the COM PP parameterization software
• Information functions integrated in the COM PP to enable fast startup of module: error messages are output in plain text
• Complete parameterization and startup also possible via the backplane bus without the COM PP when using the data handling blocks.
