88VT02B-E GJR2363900R1000 Telegram Handling Module
The telegram handling module is part of the entire master station bus control (consisting of modules 88 VA01/VA02, 88 VP01/VP02, 88 VT01/VT02). As an "auxiliary module"of the processor, it handles the serial telegrams.
However, each sub function is only performed when called by a specific command from the processor module 88VP01/VP02. The commands come from the command fields of the 48-bit data word of the program memory (see module description"Master station processor module 88 VP01/VP02",GKWE 705180). The commands are transferred in coded form via the general-bus and are decoded on the modue.
In the following, the most important functional sections are specified and their functions within the entire program of the master station bus control are described.
Features
The module can be plugged into each of the two master stations of the PRCONTROL bus system, but is only available once for each station. It is provided with two standard interfaces: one of these is used to link the module to the master station bus to which all modules of the master station (including master station coupling modules 88VK01) are connected. The second one is for the general-bus which only connects the modules 88VA01/VA02, 88VP01/VP02 and 88VT01/VT02 with each other.
Two light-emitting diodes and a test plug are provided at the front of the module. Both light-emitting diodes serve to indicate disturbances that have been detected. At the test plug, the most important transfer signals can be measured using an oscilloscope.
