Buffer Memory Modules

The MM3 module makes 2 x 64 Kbyte buffer memories available to exchange data between CPU modules The module contains a clock unit which can be optionally synchronized by keys and by receiving the DCF77 time signal (radio-based clock) This clock can be used as source for all clock function blocks of the CPU modules in the subrack ("system time", max. jitter between the individual modules: 3 ms). The time and the date are used to stamp messages of a configured message system and for diagnostic messages of the operating system

Application

Applications can be found in:

• SIMADYN systems with more that one CPU

• SIMADYN systems which require clock time

Input/Output Modules

Overview Input and output modules provide additional analog and digital inputs/outputs as well as incremental encoder connections.

Function

• The input/output channels of different CPU modules can be used with Exxx type input/output modules by means of the L/C bus.

• ITxx expansion modules supplement the CPU modules by input/output functions. Data is not exchanged through the L/C bus, but through a direct connection to the CPU module (LE bus). This means that it is especially fast (instantaneous) and does not influence data transfer with other modules through the L/C bus. However, only this CPU module can directly use the inputs/outputs of the IT modules.
